Gas Chromatography: Environmental
A poster session focusing on gas chromatography (GC) and the environment was held on Tuesday afternoon of Pittcon 2009 in Chicago.
A poster session focusing on gas chromatography (GC) and the environment was held on Tuesday afternoon of Pittcon 2009 in Chicago.
Recommended by LCGC “GC Connections” columnist John Hinshaw, topics in the session ranged from fuel oxygenates in soil to the determining of mercury in natural waters.
With so much concern about the environment in today’s society, it is no wonder why this was a well-visited poster session for conference attendees.
Gary Burce of Varian, Inc., Walnut Creek, California, presented a poster entitled “Optimized Data Handling for Automatically Calculating the Hydrocarbon Index (HI) of “Produced Waters” from Gas Chromatographic Analysis”Burce’s co-authors on the poster were Graham Shelver, Charles Van Dortmond, and Bob Lott. According to the poster, oil and gas extraction from subsea wells produce large quantities of hydrocarbon contaminated water which are disposed of directly into the oceans. Determination of the Hydrocarbon Index (HI) is required to meet environmental legislation.
Another interesting poster presentation was given by Ali Sarafraz Yazdi of Ferdowsi University of Mashhad, Chemistry Department, Faculty Of Sciences, Mashhad, Khorasan, Iran. The subject of Yazdi’s poster was the “Determination of Mercury (II) in Natural Waters by Phenylation Using Single-Drop Liquid Phase Microextraction - Gas Chromatography”According to the poster, the purpose of the work was to develop a simple, rapid, sensitive and accurate method for the simultaneous derivatization and pre-concentration of mercury (Hg2+) and the determination of the derivative, phenyl-mercury, in natural water samples using gas chromatography-flame ionization detector.
Different poster session will presented through Thursday afternoon at Pittcon.
AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma
October 31st 2024Deriving antibodies from plasma products involves several steps, typically starting from the collection of plasma and ending with the purification of the desired antibodies. These are: plasma collection; plasma pooling; fractionation; antibody purification; concentration and formulation; quality control; and packaging and storage. This process results in a purified antibody product that can be used for therapeutic purposes, diagnostic tests, or research. Each step is critical to ensure the safety, efficacy, and quality of the final product. Applications of AI/GenAI in many of these steps can significantly help in the optimization of purification and yield of the desired antibodies. Some specific use-cases are: selecting and optimizing plasma units for optimized plasma pooling; GenAI solution for enterprise search on internal knowledge portal; analysing and optimizing production batch profitability, inventory, yields; monitoring production batch key performance indicators for outlier identification; monitoring production equipment to predict maintenance events; and reducing quality control laboratory testing turnaround time.
