This instalment of the LCGC Blog investigates fundamental relationships between the structures of molecules and their interaction with different materials, in the context of online supercritical fluid extraction–supercritical fluid chromatography (SFE–SFC).
We analytical chemists have a lot to gain by applying machine learning to our field—such as by using it to efficiently reach optimal conditions for challenging separations.
The lack of proper method validation has important implications in blood alcohol concentration (BAC) determinations. We examine this issue, addressing the importance of gas chromatography (GC) for BAC determination, why certain validation procedures are important, and why accreditation bodies need to step up their game.

Reviewing your contract laboratory’s QA/QC protocols can reveal much about the accuracy of the data the lab generates. Here is what to look for.
How can you know for sure if the analytical laboratory producing your results is processing reliable data?
