Utilization of Carbon Paste Electrodes for Amperometric Detection in HPLC with Gradient Elution

Abstrakt

Method for the determination of benzophenone-1 and benzophenone-3 was developed, using HPLC with amperometric detection on glassy carbon paste electrode. Due to the utilization of gradient elution including high content of methanol, attention was paid to the stability of the electrode material and to the influence of these conditions on the determination parameters.
