The Mid Victorian Conservative Party, (SFE-HPLC) is technically more challenging. This situation arises from the fundamental incompatibility of a sample preparation procedure that ultimately produces a large volume of gas with a chromatographic technique which uses a liquid mobile phase. Maintenance of a gas-free HPLC mobile phase is g

In this context the US Environmental Protection Agency (EPA) is regarded worldwide as a main producer of official methods. So far, only two EPA methods for SFE have been produced (methods 3561 and 3560, for polycycli
