Abstract A procedure for the direct determination of tin in biological samples is described. Based on the formation of the adsorptive complex of tin with 8-hydroxyquinoline (oxine), it is possible to determine subnanomolar levels of tin after a few minutes of stirred accumulation at-0.25V. The detection limits are 0.35nM (40ppt) and 70pM (8.3ppt) for 1- and 5-min accumulation periods, respectively. The standard deviation at 50nM is 1.4%. Possible interferences were investigated. This procedure was applied to determine trace amounts of tin in blood, serum and plants.
