A capillary electrophoresis method is described for the simultaneous analysis of carnitine and short-chain acylcarnitines in aqueous standard solutions and urine samples. Samples were worked up using silica gel extraction and derivatization with 4'-bromophenacyl trifluoromethanesulfonate. Separation was performed in less

A method for the isolation and chromatography of butyrobetaine from plasma, urine, and liver is described. The recovery of [3H-methyl]butyrobetaine from spiked biological samples was from 76-80%. Spiked samples then were derivatized with 4'-bromophenacyl trifluoromethanesulfonate and the butyrobetaine 4'-bromophenacyl ester
