Abstract
Catecholamines can be detected with high sensitivity in a shortened time period, by introducing a sample containing catecholamines into an adsorption column packed with an adsorbent to adsorb catecholamines to the column, then introducing a reagent for derivatization to effect pre-column labeling and then analyzing the pre-column labeled catecholamines by means of high performance liquid chromatography. Connection of the adsorption column and a separation column of high performance liquid chromatography via a fluid path changeover valve enables to automated analysis of catecholamines.
