No single liquid chromatography (LC) detector delivers ideal results. Often with LC detectors one analyte responds more strongly than another, or may not respond at all. What is most desired is the ability to accurately measure a wide range of analytes with consistent response simultaneously.
Charged Aerosol detection (CAD) is a mass sensitive technique for determining levels of any non-volatile and many semi-volatile analytes after separation by liquid chromatography. This technique provides consistent analyte response independent of chemical characteristics and gives greater sensitivity over a wider dynamic range. An analytes response does not depend on optical properties, like with UV-vis absorbance, or the ability to ionize, as with mass spectrometry (MS). The presence of chromophoric groups, radiolabels, ionizable moieties, or chemical derivatization is needed for detection.

Measuring Nitrous Oxide & Methane from Feedyard Surfaces - the NFT-NSS Chambe...LPE Learning Center
Full proceedings at: http://www.extension.org/72909 Accurate estimation of greenhouse gas emissions, including nitrous oxide and methane, from open beef cattle feedlots is an increasing concern given the current and potential future reporting requirements for GHG emissions. Research measuring emission fluxes of GHGs from open beef cattle feedlots, however, has been very limited. Soil and environmental scientists have long used various chamber based techniques, particularly non-flow-through - non-steady-state (NFT-NSS) chambers for measuring soil fluxes. Adaptation of this technique to feedyards presents a series of challenges, including spatial variability, presence of animals, chamber base installation issues, gas sample collection and storage, concentration analysis range, and flux calculations.

Recent Advances in Handheld X-Ray Fluorescence-Based Alloy PMI/Material TestingOlympus IMS
Recently, a number of improvements related to accuracy, ease of use, speed and durability have been instituted in Handheld (HH) X-ray fluorescence (XRF) instruments. These advances are explained in practical terms, and the impact that each advance will have on the end user. This presentation is intended for those responsible for plant piping system maintenance and safety, and reinforces the practical usage and value of nondestructive HH XRF analysis in positive material identification (PMI) of alloys. Applications of useful low-compositional level elemental results (parts per million in magnitude) in conjunction with API corrosion guidelines will be covered (i.e. API RP 578 and RP 939-C). Additional compositionally-derived preventative maintenance techniques will also be included. Supplementary to the API corrosion guidelines application, an outline of HH XRF technology, its traditional alloy analysis uses, and distinct relevance to metallurgical & maintenance engineers will further illustrate the significance of recent innovations.
A systematic and targeted approach in applying improvements to software, firmware and hardware functionalities of a HH XRF instrument have all blended into a new era for the technique. Throughput and duty-cycle achievements have allowed a greater user impact when utilizing HH XRF during both uptime and downtime maintenance activities. Connectivity improvements to the technology allow remotely generated data to have an immediate use for users. Most notably, this recent set of computational improvements positions HH XRF into an analytical range rivaling aspects of laboratory grade XRF analysis while maintaining portability.

Liquid Sensing: Visible light absorption spectroscopy and colorimetry are two fundamental tools used in chemical analysis. Most of these light-based systems use photodiodes as the light sensor, and require similar high input impedance signal chains. This session examines the different components of a photodiode amplifier signal chain, including a programmable gain transimpedance amplifier, a hardware lock-in amplifier, and a Σ-Δ ADC that can measure a sample and reference channel to greatly reduce any measurement error due to variations in intensity of the light source.
Gas Sensing: Many industrial processes involve toxic compounds, and it is important to know when dangerous concentrations exist. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of toxic gases. This session will describe a portable toxic gas detector using an electrochemical sensor. The system presented here includes a potentiostat circuit to drive the sensor, as well as a transimpedance amplifier to take the very small output current from the sensor and translate it to a voltage that can take advantage of the full-scale input of an ADC.
Process Development for Continuous Flow-Through Polishing Purification for mA...Merck Life Sciences
View the interactive recording here: https://bit.ly/2JYehee
Abstract:
Over the last several years, the biopharmaceutical industry has had a significant focus on connected and continuous processing to improve both process economics and plant utilization. As opposed to the traditional polishing trains comprised of bind-elute chromatography operations, an all flow-through polishing train easily enables connected and continuous processing while simultaneously improving process economics, flexibility, and productivity. Leveraging commercially available and novel prototype chemistries and devices, we investigated how a properly designed flow-through polishing train can be used to meet the stringent demands expected for mAb polishing purification. A streamlined methodology will be described to investigate the performance of individual units as well as synergies between technologies. For both individual technologies and connected processes, results will be discussed on their ability to meet purity and yield targets robustly. Finally, we will show how leveraging the integrated combination of unit operations can result in improved performance over the standard batch, segregated processing paradigm.
In this webinar, you will learn:
• New process design for continuous flow-through polishing and its operational robustness
• Economic benefits (43% savings in COGs) of implementing a robust flow-through polishing toolbox

In the pharmaceutical arena there is great interest in solid core technology, where there is a broad range of sample types as well as requirements throughout the process of developing new chemical entities. The presentation looks at how solid core technology can be readily adapted to cope with the challenges associated with the pharmaceutical sector, looking at various sample matrices and molecular entities, from small molecules to large biomolecules. The presentation gives an insight into how varying the solid core to porous layer allows the user to optimize separation performance by reducing extra band broadening. Data presented demonstrates how this technology is more robust than fully porous systems when analyzing biological extracts, routinely used in DMPK departments, resulting in longer column lifetimes.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

• Process monitoring – feedback for water
treatment may improve the efficiency of the
treatment process – use fewer chemicals to
achieve require effluent emission limits
• Measurement of Se, As for compliance with
Steam Electric Generating Effluent
Guidelines
• Monitoring of treatment of wastewater
by biological based treatment systems
• Measurement of Corrosion Products (e.g. Fe,
Ni, Cr and Mn) to improve operating
efficiency
• Measurement of Elements in Nuclear Power
Plant Applications (e.g. Pb, Cu, Fe)
• Reduce laboratory analysis costs
4. XRF BasedWater
Analyzer Basics
• Xact 920 Utilizes ED-XRF as analytical technique
• Water is spray dried and sampled onto filter tape
• The resulting filter tape deposit is analyzed by XRF
• Builds on two technologies developed and
commercialized by Cooper Environmental
• Ambient Air XRF Analyzer (over 100 in field)
• Quantitative AerosolGenerator (Developed
for Calibration of PM CEMS for the Power
Industry)
• Instrument can measure up to 65 elements
simultaneously
4
5. XRFTheory
• X-ray source is electrically powered NOT a
radionuclide source
• Incoming X-rays eject an inner shell electron
• Electrons from higher shells fill the vacancy
• This process releases energy in the form of
fluorescingX-rays
• Energy is characteristic of each element
• Intensity or brightness is related to the mass of
each element
5
6. Strengths of
XRF
• XRF utilizes inner shell electron transitions so
the response is not dependent on what the
element is chemically bound to
• Can measure a wide range of elements
simultaneously
• XRF is non-destructive – so samples can be
reanalyzed later
• XRF is very stable – calibrations can last for
years
• XRF response is linear over the a wide
concentration range (over 5 orders of
magnitude) – this means no additional
standards required depending on concentration
range
