A method for separation of amino acid methyl or phenyl thiohydantoins by GLC on a short glass capillary column is described. Calculations of required parameters of the capillary column are presented. By the described methods, nineteen of twenty silylated methylthiohydantoins were separated in one ru

A specific, sensitive, and accurate assay for quantitation of verapamil has been developed. The method involves a single extraction step with n-heptane, followed by evaporation at room temperature under nitrogen. 0.1 pi of the extract was injected into a capillary column coated with crosslinked 5% p
