摘要：
A process removes FMOC--OH which is an undesirable by-product of the derivatization of amino acids by FMOC. The process uses a silicone rubber membrane extractor cell. The sample containing the FMOC--OH is held in a silicone rubber tubing, while pentane flows past the outside of the tube; the FMOC--OH is thus extracted from the sample into the pentane. The process is integrated into a conventional high performance liquid chromatography system and is readily automated.
