- Corrosion coupons exposed for longer periods (e.g. 9 months) showed lower corrosion levels than shorter exposures (e.g. 30-60 days), calling into question the ability to accurately pro-rate long exposures.
- "Sister" coupons exposed together in the same location often showed significantly different corrosion results, suggesting lack of repeatability. Higher VOC levels may contribute to disparity between sister coupons.
- For more consistent results, it is recommended to expose coupons for 90 days and use multiple coupons per location, as shorter or longer exposures and single coupons can produce unreliable data.
The document describes a student's lab experiment investigating the effect of temperature on the activity of the enzyme catalase. Catalase breaks down hydrogen peroxide and was tested at four temperatures (3°C, 25°C, 45°C, and 60°C) using chicken liver. The student measured gas pressure over time for each trial and found that the enzyme worked best at 45°C based on the peak average pressure. Limitations included a lack of time, materials, and temperatures tested to draw stronger conclusions.
This document summarizes an experiment that tested the effect of pH on the activity of catalase enzymes extracted from potatoes and chicken liver. The results showed that potato catalase activity was highest at pH 7 and decreased equally as pH increased or decreased. In contrast, liver catalase activity remained high from pH 7-9 but significantly decreased in acidic pH 5 conditions. This suggests enzymes are adapted to function optimally in environments similar to where they naturally occur. Limitations included a small number of trials and narrow pH range tested. Improving the experiment would involve more trials across a wider pH range.

Claus Sulfur Recovery Tail Gas Applying 100 Million Hours of Operational Time...Ives Equipment
The measurement of H2S/SO2 in Claus sulfur recovery unit (SRU) tail gas has been adequately addressed by UV spectroscopy for over 40 years. Reliability of the analytical principle was established in the first generation of analyzers and in the second generation sample handling was improved to the point where automatic control if not universal is at least considered the norm. With a deep understanding of the process and a population of 1,100 second generation analyzers it was possible in the third generation to address failure modes external to the analyzer. Reliability is not limited to the analyzer / sample system; it extends to the process and contains elements of health and safety. Analyzer professionals are compelled to look beyond what we consider our "deliverables", to address abnormal operations and bad piping design. The paper combines extensive feedback from analyzer professionals and a survey of sulfur recovery operators to address the external failure modes. Looking back on 100 million hours of operational time and one year of field testing the third generation analyzer the paper discusses reliability as viewed by the real end use customer; Operations.
The document summarizes tests being done on acrylic samples to understand how their properties change under different conditions. Samples have been submerged in distilled water, mineral oil and LAB, and their weights, dimensions and transmittance measured over time. Transmittance decreased most for samples in mineral oil and slightly for those in water. Further tests will subject dry samples to stress, temperature cycling and exposure to freon to evaluate property changes and outgassing. The full tests aim to minimize systematic errors from acrylic vessels in detectors.
The document summarizes tests being done on acrylic samples to understand how their properties change under different conditions.

Transmittance of samples submerged in different liquids has also been tracked. Further tests planned include drying samples and stress testing both dry and non-dry samples to analyze changes. Additional tests will explore outgassing, temperature cycling, low temperatures and freon compatibility. The goal is to minimize systematic errors from acrylic vessels in detectors.
Tracer Cert technical note no 1 ppb & sub ppb water vapour standards, revised...John Thompson
The document describes a method for creating precise water vapor standards in the parts per billion (ppb) and sub-ppb range using refillable diffusion tubes. Water is pipetted into the tubes, which are then weighed over time as the water vapor diffuses out at a controlled temperature. Regression analysis is used to determine the rate of weight loss, allowing calculation of emission rates and concentrations achievable at different gas flow rates. Precise diffusion tubes can generate water vapor standards in the low ppb range needed for quality control in semiconductor manufacturing.

This article summarizes the results of a study that tested the fade resistance of lithographic inks in real-world outdoor exposures in Florida and Arizona, and how those results compared to accelerated laboratory testing using a xenon arc method. The real-world exposures showed a wide range in fade resistance between different ink colors and formulations. The laboratory xenon arc testing was found to closely mimic the real-world results in terms of ranking ink performance and degradation patterns, while providing results much faster than the outdoor exposures. The study establishes outdoor and laboratory xenon arc testing as effective methods for evaluating ink fade resistance.
This document describes a patented process for producing micro-particle ammonium nitrate (MP-AN) through atomization. MP-AN is produced by spraying an 83% or 85% AN solution doped with a surfactant called NSol 1000. Initial testing showed MP-AN had properties making it suitable for use in commercial explosives, including higher densities and detonation velocities than conventional ANFO. Further iterations improved the spraying process, allowing higher production rates of spherical MP-AN particles with densities up to 1.44 g/cc. Field tests of MP-ANFO containing MP-AN showed detonation velocities over 6,000 m/s and fragmentation equivalent to emulsion explosives when used underground.
Evaluation of transdermal drug delivery systemSagar Savale
This document discusses the evaluation of transdermal drug delivery systems. Key aspects that are evaluated include physicochemical properties, adhesive properties, in vitro studies, in vivo studies, stability studies, and toxicological studies. These evaluations are important to ensure consistency between batches in terms of quality, performance, reproducibility and stability, and to predict factors that may influence drug delivery.
This test method determines the ignition loss of cured reinforced resins by heating samples in a crucible until only ash and carbon remain, then further heating the residue to remove carbon. It provides a measure of resin content for samples with glass fiber reinforcement where the resin completely decomposes during testing. The standard establishes procedures for specimen preparation, conditioning, testing, and reporting. A precision study found the within-laboratory variability (Sr) was 2.57% for laminate and 0.289% for pultruded rod, and between-laboratories reproducibility (SR) was 7.21% and 0.940% respectively.

1) A trial was conducted injecting an enhanced calcium sorbent called Sorbacal® SPS at Great River Energy's Stanton Station to reduce SO2 emissions and meet regional haze compliance targets.
2) The trial successfully achieved over 85% SO2 removal and emission rates below 0.14 lb/MMBtu, meeting the target.
3) Monitoring of the electrostatic precipitator performance showed only minimal impacts from the sorbent injection, indicating good compatibility between the enhanced calcium sorbent and ESP operation.

Is Any Measurement Method Optimal for All Aggregate Sizes and Types? KBI Biopharma
This document discusses challenges in analyzing protein aggregates using analytical methods. It provides examples of unusual aggregation phenomena observed:
1) An "aggregate" peak seen by SEC in a stressed sample was shown to be a partially denatured monomer using SEC-MALLS and sedimentation velocity.
2) Freeze/thaw stress generated transient, metastable oligomers in a protein that were difficult to detect by SEC due to their stickiness. Sedimentation velocity detected a much higher level of aggregates.
3) Different analytical methods can perturb aggregate distributions in different ways by dissociating or creating new aggregates. Method selection depends on the aggregate properties and no single method is optimal in all cases.
The oxygen transmission performance of contact lenses would directly influence feelings and experiences of consumers, and, correspondingly, the sales volume of contact lenses would be affected. The test for oxygen permeation performance of contact lens has become a main concern of the manufacturers.
This document provides instructions for an experiment to determine the concentration of lead in soil samples using atomic absorption spectroscopy. Students will analyze three related soil samples and develop a hypothesis about the expected trend in lead concentrations between the samples. They will then prepare lead standards, digest the soil samples to extract lead, and use an atomic absorption spectrometer to measure the lead concentration in each sample. The results will be analyzed to compare the expected and measured trends in lead levels across the samples.
The document discusses the use of accelerated stability studies conducted at higher temperatures than intended storage conditions to quickly identify degradation processes in drug formulations. It defends this approach by stating that using elevated temperatures increases degradation rates, allowing stable formulations to be developed more quickly through identifying conditions and excipients that slow degradation over long periods at lower temperatures. While this approach does not guarantee detecting all events, it has generally proven reliable.

ABSTRACT: Recent experiences with Purafil Corrosion Classification
Coupons suggest some guidelines on their use and interpretation of
results for measuring the corrosive nature of preservation
environments. The coupons, rated for a 90-day exposure, are known to
be less reliable when exposed for a shorter period. However, a set
of Purafil corrosion coupons was left out for a nine-month period,
showing low levels of corrosion. Subsequent tests with 30- and 90-
day exposure periods showed much higher levels expected for the site.
This brings into question the ability of the current lab analysis to
accurately pro-rate long and possibly short exposures to the standard
90-day analysis level. Test variability was suggested in field tests
comparing a 90-day exposure with a series of concurrent 30- and 60-
day exposures under the same conditions. Repeatability is in
question from the results for "sister" coupons exposed together at
around 30 days.
PURAFIL CORROSION CLASSIFICATION COUPONS. This test is designed to
monitor contamination from inorganic corrosive gas conditions in
museums, libraries and archives. The coupons react with sulfur
dioxide, oxides of nitrogen, and chlorine. They should not react
significantly with volatile organic compounds (VOCs).
In this test, a prepared pure silver coupon is exposed for a
specified period of time, then returned to the lab. At the lab,
electrolytic stripping determines the amount of corrosion compounds
on the coupon. Corrosion results are listed for chlorine compounds
(AgCl), sulfur compounds (Ag2S), and all other compounds under the
category of "unknowns" (Ag-Unk). Corrosion from nitrogen oxides and
from silver oxides are included in the unknowns category. Regardless
of the exposure period, lab results are corrected to a normalized 90-
day exposure.
The Purafil coupon test is based on the gaseous corrosion "coupon
test" developed by the Instrument Society of America (ISA), detailed
in Reference 1. The Purafil test is, however, proprietary and is
designed to test for lower corrosion levels sought by museums,
libraries and archives. Costing roughly $500 for a set of six coupon
tests, it is substantially less expensive than the typical ISA test
at $300 per coupon. One coupon test is often inadequate to
characterize an environment.
2. At an average cost of $85 per coupon, a good shelf life, and the
ability to have individual coupons analyzed, the test is economical
for general survey work in environmental assessment. The test also
has the vested interest of a company committed to the conservation
field. Purafil is interested in the use of the test, freely
discussing its applications and problems.
NORMAL EXPOSURE PERIOD. Users who are interested in results as soon
as possible many expose the coupons for only 30 days. The average
exposure reported by Purafil for museum and archives applications is
about 80 days. In the lab analysis the results are always corrected
(pro-rated) to a standard 90-day exposure.
Purafil recommends an exposure period of 90 days to reduce the chance
of analytical error. They say this should give more accurate results
since the amount of corrosion being stripped will be more significant
and no correction multiplier is used. Some expose the coupons for a
period shorter than 30 days with expectedly unstable results. This
is due to the low amount of corrosion being stripped and the high
correction multiplier to normalize to a 90-day exposure.
NINE-MONTH EXPOSURE. A set of Purafil corrosion coupons was left out
for a nine-month period at the Georgia Department of Archives and
History. Despite clear corrosion and discoloration, lab analysis
showed only moderate to low levels of corrosion when corrected to a
90-day exposure. Purafil notes that many types of corrosion can be
very visible with only moderate levels of contamination. Subsequent
tests for periods closer to 30 days consistently showed much greater
corrosion levels, closer to the levels suspected for the site.
Graph 1 shows the corrosion levels for two areas tested. The first
set of three tests shows a higher total corrosion at 96 days than the
two 9-month exposures in the same area. The second set of six tests
show even shorter exposures give greater corrosion levels.

4. In all these tests the variability seems to be greater in the unknown
silver compounds (Ag-Unk).
This brings into question the ability of the current lab analysis to
pro-rate very long exposures to the standard 90-day analysis. While
coupons are not usually exposed for nine months, there is some
concern over the regular use of 30-day and 60-day exposures, when
used in comparison with the rated 90-day exposures.
30-60-90 DAY EXPOSURES. The initial 9-month comparison led to a
second series of tests comparing 30-, 60- and 90-day exposures.
Since the 9-month test was compared to coupons exposed in the same
space but at different times, this second test was designed to expose
coupons concurrently. In this way any variations of contaminant over
the exposure period would be caught in the concurrent exposures.
With the help of Purafil, field tests were done to compare a 90-day
exposure with three (3) concurrent but sequential 30-day exposures
under the same conditions.

Since each corrosion level is normalized to a 90-day exposure, the
longer exposures should approximate the average of the other periods.
This is not the case. This shows a lack of repeatability for the
absolute numbers in the tests, and suggests the need to refine the
exposure period weighting system.
DUPLICATE "SISTER" COUPONS. Repeatability of the tests has always
been a concern ever since coupons used in the same general area were
observed to have significantly different results. Over the past year
duplicate "sister" coupons have been exposed by Garrison/Lull at
various sites. Sister coupons are from the same coupon batch, and
are handled, exposed and returned identically, never separated by
more than a foot for more than a few minutes. For the tenure of
their exposure they were exposed to essentially the same
contamination.
Graph 4 shows the results of six such tests.

Each set of two coupons was exposed for exactly the same time in exactly the
same location. All but the first and last tests showed alarmingly different
levels of corrosion.
CROSS-INDICATION WITH VOCs. In some cases sister coupons were
exposed in environments where separate tests showed high total VOC
levels. This was the case for the fourth and fifth set of sister
coupons (Graph 4). In the fourth set, the total VOC levels measured
415 ppb, about three to four times a typical level. In the fifth
set, the total VOC levels were 1350 ppb, about ten times typical
levels. This may show a cross-indication on the coupons, suggesting
that the coupons may be reacting with VOCs in some unstable way.
This might contribute to the disparity between the sister coupons.
The first set of sister coupons was exposed with a VOC test that
showed very low levels, 6 ppb. The second set of sister coupons was
exposed in the same historic house with a total VOC monitor measuring
normal levels of total VOCs, 121 ppb. The third set of sister
coupons was exposed without the benefit of a total VOC test. The
last set had a VOC test showing 155 ppb.
In these tests VOC levels were measured with a 3M 3500 Organic Vapor
Monitor exposed for 4 to 7 days. This monitor will pick up most
large VOCs, but will not show exposure to smaller VOCs such as
formaldehyde and acetic acid.
CONCLUSIONS. From these tests several guidelines emerge for
meaningful use of these coupons:
7. 1. Longer exposure periods tend to show lower contamination levels.
2. For more consistent results try to exposed coupons for 90 days,
but avoid exposure periods significantly longer than 90 days.
3. When used for relative comparisons, coupons should be exposed for
the same period of time.
4. For more reliable results use two or three coupons per location.
Cluster the coupons so they are exposed to the same environment.
If there is a wide disparity between "sister" coupons, suspect
other contaminants, such as VOCs. If possible, use a total VOC
monitor concurrent with the coupon test, to see if high VOC
levels may skew the corrosion test results.
