Green Analytical Chemistry (GAC) is a concept of designing analytical methods that are friendly to both chemists and environment. It is necessary for the GAC-based methods to retain the same analytical performance (e.g., accuracy, sensitivity) as those by their conventional counterparts. Large solvent consumption is particularly concerning in a food analysis where complicated sample extraction and chromatography are routinely practiced. Supercritical fluid is a state of matter just like gas or liquid, and the characteristics of CO2 supercritical fluid are nonflammability, easy handling, and low toxicity, which are relevant to the operator safety. This webinar will show the characteristics of supercritical fluids CO2, the practicality of analytical techniques using it, and the applicability to GAC.

Analyzing Triacylglycerols (TAGs) is essential to evaluate the quality and functionality of oils and fats. Chromatographic separation by typical methods that include GC and HPLC might be challenging due to a large number of TAGs species. Supercritical Fluid Chromatography (SFC) is one chromatography method that uses supercritical fluid (i.e. supercritical carbon dioxide) as a mobile phase. Here, we introduce the workflow of method scouting of SFC using Method Scouting Solutions and how to establish the optimized analytical method for TAGs species in natural oils and fats.
