title: Determination of traces of hemoglobin by square wave stripping voltammetry at a silver microelectrode.
abstract: An electrochemical method was developed for the determination of traces of hemoglobin (Hb) by adsorption square wave voltammetric stripping at a bare silver microelectrode. Under optimum conditions the proposed method provided a linear response over the hemoglobin concentration range 5 to 100 nmol/L. The detection limit was 3 nmol/L. The relative standard deviation was 4.5% for 6 successive determinations at 50 nmol/L Hb. Other chemicals present in the sample did not interfere.
