Selective electrochemical (EC) HPLC Detectors measurements can identify several chemical compounds which might be oxidised or minimized during the existence of electric powered opportunity at pretty low concentrations.
Most HPLC detectors get the job done by converting a physiochemical residence of the analyte into an electrical signal. To paraphrase, a detector ‘sees’ a sample and sends signals at consecutive time details through the sample operate.
