The Use of Long Capillary GC Columns for Urinary Phenolic Acids from Catecholamines and Analogues
Glass capillary columns are routinely being coated with a phase mixture based on SE-30 Ultraphase for use in analysis of urinary phenolic acids, using 100 m columns of 0.5 mm bore. These have a resolving power of ~105plates, depending on the compound analyzed. An account is given of the preparation of these columns and of their use in examining urinary constituents (human, rat) and in metabolic work with compounds related to catecholamines. When measuring previously unauthenticated compounds, identities must be confirmed by independent means because some of the numerous urinary constituents may interfere.
