APPLICATIONS OF HIGH PERFORMANCE LIQUID CHROMATOGRAPHY WITH ELECTROCHEMICAL DETECTION IN CLINICAL CHEMISTRY... 

The value of electrochemical detection following high performance liquid chromatography is compared with that of the more widely used optical methods of detection. Its advantages are illustrated by its application to three areas of clinical chemistry that had previously posed analytical problems. Its sensitivity allowed its use for the measurement of plasma catecholamines. Its selectivity was employed to produce rapid methods for the determination of urinary levels of catecholamine and tryptophan metabolites. Finally, its value for the estimation of urinary oxalic acid is shown. Future developments such as increasing the range of detectable compounds by derivatization are briefly discussed.
