Flash Chromatography
Flash chromatography is a type of preparative liquid chromatography commonly used in the separation of organic compounds.
Flash chromatography is a type of preparative liquid chromatography commonly used in the separation of organic compounds. It utilizes a plastic column filled with some form of solid support, usually silica gel, with the sample to be separated placed on top of this support. The rest of the column is filled with an isocratic or gradient solvent that with the help of pressure, enables the sample to run through the column and become separated.
2009 flash demand by industry.
Flash chromatography has become a popular method of normal phase separation through purification. While flash chromatography is typically a low-pressure technique, scientists are using vacuums or pumps at medium pressures to speed up the separation process. The columns are packed with a silica adsorbent of defined particle size usually between 30–60 μm, although other packings with other particle sizes are also used. Mobile phases with low viscosity require smaller particle sizes.
Demand for flash chromatography comes primarily from the pharmaceutical and biotech industries accounting for nearly three-fourths of the market. The technique is commonly used in the separation of synthetic organic compounds, which are particularly useful in drug discovery. Flash chromatography systems assist laboratories focusing on combinatorial chemistry to streamline their purification steps.

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.
