Term: electrochemical detection in flowing systems https://doi.org/10.1351/goldbook.09170 Definition: Electrochemical techniques (potentiometry, amperometry, voltammetry, coulometry, conductimetry) used for analyte detection in flowing systems. Note: Measurement in flowing systems (e.g. flow injection analysis) should be differentiated from batchwise determination in individual fractions obtained after separation (e.g., high performance liquid chromatography, capillary zone electrophoresis).
