Abstract: This paper presents the preparation and application of two new arrangements of silver solid amalgam (AgSA) electrodes for measurements in flow systems  tubular detector based on compact AgSA, and flow-through detector (or reactor) prepared from porous AgSA. Both electrodes were tested for electrochemical determinations of reducible inorganic (Cd2+, Zn2+) and organic (4-nitrophenol, lomustine) compounds under FIA with amperometric detection (Cd2+, Zn2+, 4-nitrophenol) and flow-DPV (lomustine). Furthermore, by combination of the porous reactor with immobilized enzyme and tubular detector the flow amperometric enzymatic biosensor was constructed for determination of glucose in a sample of honey and cholesterol and sarcosine in model samples.
