Test results using the NIOSH analytical method S184 for organic tin (7440315) compounds are reported. The technique involves filter extraction with an organic solvent or by direct acid digestion, and analysis by atomic absorption with either atomization or generation of tin-hydride. Analytical chemicals and equipment are described. Data on recovery rates, effects of nitric-acid on tin absorbance and vapor loss is included. The method was unsatisfactory due to poor recoveries from filters, variations in graphite tube characteristics, and erroneously high recoveries during repeated tests.
