Description:"A method is described for the sampling and analysis of o-tolidine (119937) , based on a method successfully used for benzidine (92875). Air is drawn through a two stage sampler consisting of a high efficiency fiber filter and a silica gel bed which collects o- tolidine and its salts. The filter and sorbent sections of the sampler are transferred to stoppered tubes and the o-tolidine is desorbed. A triethylamine/methyl-alcohol solution is injected into a high pressure liquid chromatograph. Peak readings are obtained and compared with a standard calibration curve. This method can detect 0.15 to 6.5 micrograms of benzidine per sample (3 to 130 micrograms per cubic meter for a 50 liter air sample) using 0.5 milliliters of desorbing solution and a 10 microliter injection into the liquid chromatograph. The authors suggest that the range of detection for o-tolidine should be similar to that for benzidine. The limit of detection for o-tolidine is predicted to be about 0.05 micrograms per sample." - NIOSHTIC-2
