PFAS Testing Solutions from Greyhound Chromatography.
As a global supplier of chromatography consumables and reference standards, Greyhound
Chromatography have brought together in this catalogue, the best products for the analysis of
PFAS compounds from the leading manufacturers in the field.
PFAS (per and polyfluoroalkyl substances) is the collective name for almost 5000 compounds
which have been produced since the 1940s. These compounds are not naturally occurring in
nature so the problems of global pollution are entirely the result of human activity. The utility of
these compounds has resulted in their rapid adoption which has resulted in them being found in
cookware, stain repellents, food packaging, cosmetics, firefighting foams and many
manufacturing processes.
PFAS are known as ‘forever chemicals’ in that they are very persistent in the environment and the
human body, resulting in increasing health risks including damage to immune systems, cancer and
thyroid hormone disruption.
Considerable research has been undertaken to develop products which are specifically suited for
the analysis of PFAS by HPLC, from sample preparation, through to analytical detection.
This brochure brings together many of the leading products used in PFAS analysis, including the
analysis of samples in water, soil, food and beverages as well as serum samples.

What are Reference Standards?
A pharmaceutical reference standard is a highly characterized material
suitable to test the identity, strength, quality and purity of substances
for pharmaceutical use and medicinal products.
The reference standard is the test, combination of tests, or
procedure that is considered the best available method of categorizing
participants in a study of diagnostic test accuracy as having or not
having a target condition.

Is Vaping the right solution for giving up smoking nicotine products?
Is Vaping just a case of smoke and mirrors?
Should we be concerned about health issues caused by vaping?
With the vast increase in Vaping being led by the thought
it can stop a users addiction of smoking, do we really have
all the facts we need to determine if this is the truth?
Although e-cigarettes date back to being invented in the
1920’s, it wasn’t until the mid 2000’s that a Chinese
company, owned by pharmacist Hon Lik, created the first
modern vaping device to be sold on the high street.
Recently there has been a lot of media coverage regarding
e-cigarettes and the affect that they have on human
health, there is almost no proven scientific evidence to
say that vaping is better for people than smoking.
We are all aware that smoking is able to cause many known
illnesses and can commonly lead to death, but new stories
have come to light recently, show that vaping has a huge
detrimental effect in the same way that smoking does.
Laws have been implemented in the US since 2016 regarding
the use of vape devices which states it is illegal to
sell e-cigarettes to minors but advertising to adults is
still permitted. There isn’t as much concern that vaping
will effect children in the UK in the same way, as we
have strict limits on the levels of nicotine that can be
included in e-liquids, whereas the US do not.
Considering e-cigarettes were introduced to the market as
a less harmful alternative to smoking, there has been an
increased concern that people have taken up vaping
although they never smoked to begin with.
Electronic Cigarettes (A vape) are small devices that
use different flavoured nicotine oils, also known as
e-juices, to create smoke in a vapour form.
A vaping device does not include or contain tobacco and
therefore doesn’t allow you to produce carbon monoxide
or tar that can be formed from resins that are active
in cigarettes.
How is vape oil (e-juice) made?
Vape juices are generally made by mixing together
different flavours and nicotine with a solvent which
is usually propylene glycol.
Sometimes people will optionally use vegetable
glycerine. The solvent that is used within the mix is
the main chemical that is included in the vape oil.
Propylene glycol is an organic chemical compound that
is most commonly used within foods as an additive to
improve the flavour, colour or texture of different
products.
Currently in the UK, there is estimated to be 3.6 million people who are vaping. It is becoming
more and more common that people have taken up vaping in place of their addictive cigarette
habit, as they believe that this will be “better” for them in the long run. It has been proven
that if there is repeated high exposure to this vapour then very harmful risks could occur.
Recently there have been many cases related to e-cigarettes and the effects that they can cause.

are a quality product.
Why is Pesticide Testing Important?
Pesticides are an effective tool used by farmers all across the globe to prevent insects, rodents and other pests from
eating or spoiling their crops. Although, because these chemical compounds are deadly to these pests, it has been
important to ensure that pesticides do not have poisonous effects past insects to humans and other aspects of nature.
However, it can be difficult for communities to police pesticides and it is not as effective to test pesticide use after it
has already been applied to a field or farm. For these reasons, there have been a number of international bodies that
have joined together to create testing guidelines to ensure that the pesticides used in the U.S., Australia, Africa and
anywhere else will not result in unwanted repercussions for humans nearby. Pesticide users and manufacturers can
use certified and approved standards to check whether their pesticides meet quality and specification requirements
to work effectively without harmful consequences.
Countries Work Towards a Common Goal
Since the 1960 formation of the Convention on the Organization for Economic Co-operation and Development,
countries including the U.S, U.K., Mexico, Japan, Chile and Germany have created a set of pesticide testing protocols.
The OECD pointed to nearly 100 testing methods for the testing of these chemicals. The international group both
creates guidelines for pesticide uses as well as tests the residue of pesticides in OECD and non-OECD countries to
study their effects and determine further usage plans.
Separate from the OECD, the Collaborative International Pesticide Analytical Council, the Food and Agriculture
Organization of the United Nations, and the World Health Organization also work to regulate safe pesticide use on an
international scale. In a 2005 report published by all three organizations outlining the quality to be used in national
laboratories, they explained the importance of using standards from approved international providers.
Protecting Bees From Pesticides
As far as humans are concerned, bees are one of the most important
insects. Though they aren't the only type of bug that pollinates plants,
they are one of the most common. Bees ensure that plants produce
fruits and vegetables. Without them, whole industries would die and
many would be without a source of food. However, pesticides meant to
rid crops of other harmful insects are having an adverse effect on bee
populations around the world.
PFAS (per- and polyfluoroalkyl
substances), known as “forever
chemicals” are found in everyday
objects. Food Packaging, paints,
cosmetics, wood lacquers, sealants ,
solar panels, fire fighting foams,
artificial grass and many more
seemingly innocent products.
Generally used to prevent corrosion
and make products waterproof and
stain-resistant they are present in our
everyday life. Unfortunately they do
not break down in our environment
and as a consequence are “forever
present”. Greyhound Chromatography provides a wide range of Chromatography related products for testing and analysis of PFAS and many other 'forever chemicals'.
Are all PFAS toxic to humans?
This is a question that remains to be answered.
Research over many years will provide the data
needed to analyse the impact PFAS has on the
environment. Some PFAS, sometimes used in
construction materials are not released into the
air or water table when it rains but they are
released when buildings are demolished and the
debris is sent to landfill.
Some PFAs are of a more immediate concern as they are released into the environment when they
are used or when they come into contact with water. Small residual PFAS molecules wash off
easily and are carried to the soil, air and water very quickly. Many short-chain PFAS dissolve in
water. Gradually, over time, the PFAS sinks to the depths of oceans and rivers, settles in the
sediment and becomes a concern as marine life feeds on plants and other animals that are in the
sediment. Some PFAS such as PFOA act like detergents, they repel water and rise back to the
surface, they are then released into the atmosphere as droplets. Some scientists believe that spray
from the oceans is the biggest source of atmospheric PFAS.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Complete Guide to the
Merlin Microseal™
for Gas Chromatography
2. Introduction
The Merlin MicrosealTM
from Greyhound Chromatography
is a microvalve alternative to the conventional silicone
rubber septa used in gas chromatography (GC). Its unique
design gives it high pressure capability and resistance to
wear which results in long life and excellent
chromatographic performance. The Microseal is available
for all major GC manufacturers’ instruments.
FEATURES
• Eliminates septum coring and crumbling into the
injection port liner
• Reliable performance during extended runs
• O-ring detail seals needle during injection
• Duckbill seals more tightly at higher pressures
• Low insertion force for easy manual injections
How the Microseal Works
A GC injection port septum performs two discrete
functions. It seals the port while the syringe needle is
inserted and also while the needle is not inserted. The
Microseal is distinct from traditional septa in that the
Microseal has two independent sealing mechanisms to
perform these functions. O-rings seal the syringe needle
during sample injection. A duckbill valve seals the
injection port during analysis, but allows the needle to
slide through without damage. In contrast, a conventional
septum is repeatedly pierced by the syringe needle and
eventually leaks or sheds septum particles into the
injection port liner. Because the two seals perform
separate, individual functions and are only slightly
distorted in operation rather than being pierced, the
Microseal can be made from a high-temperature, wear-
resistant fluorocarbon elastomer. In combination with the
cone-tipped needle, this means the Microseal will not
shed pieces into the injection port, even after thousands
of injections.
The cut-away views show the location of the individual
seals and the diagram at the lower right illustrates the
following sequence of Microseal functions.
1. Pressure in the injection port, aided by a stainless
steel spring, squeezes the duckbill closed and
maintains a tight seal on the port. Higher pressures
seal it more tightly.
2. As the syringe needle enters the Microseal, the wiper
rib removes any particles adhering to the needle.
3. The O-rings then make a sliding seal around the
needle.
4. As the needle penetrates further, the tip pushes the
duckbill valve open and slides into the injection port.
The O-rings maintain the seal around the needle.
5. As the needle is withdrawn from the Microseal after
sample injection, the spring pushes the duckbill valve
closed before the needle leaves the O-rings. The port
remains sealed during the injection process.

Types of Microseals
General Purpose, Low Pressure and SPME Microseal
P/N 410 P/N 310 P/N 21-01
Microseals for use with 23 gauge Needle
General Purpose Microseal (P/N MM-410) - This
Microseal is recommended for use in most GC
applications with injection port pressures between
3 and 100 psi (20 - 690 Kpa). The General Purpose
Microseal is the best choice for most GC applications.
Low Pressure Microseal (P/N MM-310) - This is
recommended for injection port pressures between
1 and 45 psi (7 -310 Kpa). Particularly useful for fast
GC/MS applications with 530 micron columns.
SPME Microseal (P/N MM-21-01) - This Microseal was
developed for 23 gauge SPME probes, which have a
square end instead of the cone shaped tip
characteristic of syringe needles. These probes can
cause additional wear and this version provides
extended lifetime for SPME.

3. Injection Port Adapters for 23 gauge Microseals
All 23 gauge Microseals are compatible with the standard adapters shown here.
Agilent Injection Ports
The Microseal fits directly onto the septum
cup of the Agilent Split/Splitless injection
port. It requires a Microseal nut.
Recommendations for Use:
Merlin Microseal is compatible with all
Agilent autosamplers & Split/Splitless ports
(including 5890, 6890, 7890, 8890, and
Intuvo series).
Tighten the Microseal nut finger tight only. Do not overtighten.
Injection port temperature range: 50- 400°C.
Requires a blunt, cone tip, 23 gauge syringe or 23 gauge SPME
probes.
Microseal #410 is recommended for most applications (3-100 psi).
Use Microseal #310 for lower injection port pressures (1-45 psi).
Use Microseal # 21-01 Microseal for SPME.
Thermo Scientific Injection Ports
The Merlin Microseal can be used with
Thermo Trace 1300 series GCs and Thermo
Trace Ultra GCs.
Thermo Trace 1300 series GCs - The
Microseal fits directly in the inlet of the

4. New Microseal Gauge Sizes
The Merlin MicrosealTM
has traditionally been compatible only with 23 gauge syringe needles and SPME probes. However,
Merlin now offers a new selection of Microseals for different gauge sizes.
Microseals for 26 gauge or 23-26 gauge Tapered Needles
GC users may discover several benefits to using 26 gauge syringe needles. Most on-column injections will require the use of a
26 gauge or 23-26 gauge tapered needle. The smaller diameter of 26 gauge syringes can also reduce coring of sample vial
septa. The low insertion force of the Microseal prevents needle bending during injection that is common when using a 26
gauge needle with conventional septa.
P/N 610 - 26 gauge Microseal - This Microseal is compatible with 26 gauge and 23-26 gauge tapered needles and can be used
for injection port pressures between 3 and 100 psi (20 - 690 kPa). It is recommended for most 26 gauge users. This Microseal is
compatible with the standard 23 gauge adapters and nuts for all instrument manufacturers as listed on page 3.
Microseals & Adapters for PAL Arrow SPME Probes
The PAL SPME Arrow probes are large diameter SPME probes with a rugged construction that ensures longer life than
traditional SPME probes. The larger diameter of these probes does require the GC inlet to be modified but allows for faster
analysis and better sensitivity. The Merlin Microseal for PAL Arrow SPME probes reduces the insertion force for injections
and is an excellent long-life alternative to traditional inlet septa. The Arrow Microseal is available for most instruments and
both Arrow sizes (1.1 mm and 1.5 mm).
Note that all GCs require inlet modification and an adapter or nut specifically for Arrow Microseals. Arrow Microseals are
not compatible with the traditional 23 gauge adapter kits.

6. Microseals for SPME applications
The two separate sealing mechanisms of the Merlin Microseal™ make it the preferred choice for Solid Phase MicroExtraction
(SPME). The duckbill seal allows the SPME probe to push through while the O-rings maintain a seal.
SPME probes typically have square or bevelled ends which can core or damage conventional silicone rubber septa. This
results in short septum lifetimes and often causes septum crumbs to fall into the injection port liner, where they can
interfere with the analysis.
As a solution to this problem, the Microseal is recommended by manufacturers and distributors of SPME probes and is
specifically required for bevelled tip probes. The Merlin P/N 21-01 Microseal has been developed specifically to resist wear
when used with SPME probes.
The Microseal requires 23 gauge SPME probes to seal properly during desorption. Do not use 24 gauge probes, they are too
small in diameter to seal in the Microseal.
Microseal Compatible SPME Probes
Bevelled Probes
The orientation of the bevel on the SPME probe with respect to the Microseal is critical so that the beveled probe can push
through the lips of the duckbill without damaging them. Incorrect orientation of the bevel on the probe will cause the tip to
pierce or damage the inside surface of the Microseal. The figure below shows the correct orientation of the bevel with
respect to the Microseal. A suggested procedure is to record the orientation of the Microseal in the port and then to install
the SPME Probe in the autosampler so that the bevel on the probe is aligned properly as shown in the figure.

7. Microseal Installation
1. Follow the standard procedure to prepare the
instrument for a septum change.
2. Remove the injection port nut and the septum.
Remove any pieces of septum that are stuck to the
injection port. Clean or replace the injection port
liner to remove any septum particles which may have
accumulated from silicone rubber septa.
3. If your instrument requires a Microseal adapter,
mount it on the injection port finger-tight.
4. Place the Microseal in the septum cup. Push it down
gently with your finger to seat it in the septum cup.
5. Screw on the Microseal nut finger-tight. Do not
overtighten.
Choosing a Syringe for 23 gauge Microseals
The correct 23 gauge syringe needle diameter and
needle tip shape is all that is required for the Microseal
to function properly. Autosampler compatibility
determines the other syringe parameters such as needle
length, syringe barrel, and plunger configuration.
Microseals also work well with manual injection
including the Merlin Microshot.
Microseal Compatible Syringe Needles:
Microseal Performance
Microseals function well over the entire range of GC
injection port temperatures (50-400C) and within the
specified pressure ranges of 3-100 psi (20-690 Kpa) for
the General Purpose and SPME versions and 1-45 psi (7-
310 Kpa) for the Low Pressure version. The resistance to
wear is valuable in keeping the injection port liner free
of septum particles which can cause sample adsorption
or decomposition. Because the duckbill seal is enhanced
by increase pressure,
Microseals perform very well at higher injection port
pressures. Microseal lifetimes can vary depending on
sample composition, operating conditions and
laboratory environment. Lifetimes range from over
10,000 injections to as few as 1,000. Microseals should
be replaced when the leak rate reaches several mL/min
or when the inlet system will no longer hold column
pressure. Thermal conductivity leak detectors used with
helium or hydrogen carrier gas are extremely sensitive
and may show full scale signal with a few microliters/
minute leak rate. This is useful when searching for
column fitting leaks but are not helpful in measuring
Microseal leaks. Most all gas chromatographs use
pressure controlled inlet systems so retention times
remain stable with minor variations in total inlet flow.
Small Microseal leaks, which add to septum purge flow,
are not as critical as leaks at a column fitting, for
example.
When leaks occur they are typically caused by the
accumulation of material in the duckbill lips. Traces of
samples containing derivitizing reagents or high
concentrations of non-volatile material can leave traces
on the needle tip. The residue can gradually accumulate
in the duckbill lips which can interfere with the ability of
the duckbill to seal. A small amount of glass wool in the
injection port liner can wick away sample from the tip of
the needle to alleviate this problem.
Safety
Read and follow the directions and safety precautions in
the instrument manual for replacing the septum.
1. The injection port and nut may be hot.
2. The injection port may be under pressure.
3. Wear safety glasses as you always do in the
laboratory.
4. Use particular caution with flammable carrier gases
like hydrogen.
The 21-01 Microseal should last for over 1,000 insertions
when used with SPME probes.
In testing, the P/N 410 General Purpose Microseal will
also give reasonable lifetimes with square tipped probes
but is not recommended for use with bevelled probes.
