In HPLC,analyte Detectors Can Consist of Fluorometers,photometers,and Electrochemical Detectors

In HPLC,analyte detectors can consist of fluorometers,photometers,and electrochemical detectors.An electrochemical detector measures an electroactive analyte by:

A) monitoring the current that is generated by oxidation or reduction reaction under a constant potential voltage and that is proportional to the concentration of analyte.
B) measuring an electrical potential difference between two electrodes.
C) measuring the radiant energy given off when the chemical bonds of an element are dissociated and the element is placed in a ground or atomic state.
D) measuring both an alteration in enzyme level and a redox reaction at a potentiometric ion-specific electrode.
