On Wednesday, January 17, Francois Huby of The Dow Chemical Company will present a talk titled “Comparative Evaluation of ‘Carbon Centric’ Gas Chromatography Detectors for Volatile Organic Compounds Analysis.” The presentation is scheduled to take place at 10:55 a.m. in Room 372 D.
According to Huby, volatile organic compound (VOC) analysis currently is performed using gas chromatography (GC), and the most common detection methods are flame Ionization detection (FID) and mass spectrometry (MS). Both detection methods require calibration using analytical standard solutions at known concentrations of each detected compound. For complex samples, the preparation of standard solutions, calibration of the chromatographic system, and analysis of the chromatographic data can be time consuming and costly. Carbon-centric detectors directly measure the mass of carbon corresponding to each chromatographic peak. Knowledge of the eluted compounds’ chemical nature, possibly obtained by using a spectroscopic detector, enables a direct unbiased estimation of the mass of the compounds eluted from the column. In addition to delivering accurate VOC levels, such detectors also simplify both the calibration of the system and the data reduction step of the analysis. In this presentation, Huby will compare several carbon-centric detectors in terms of performance, ease of use, and cost.

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.
