Nitroethane (Analytical Method No. S219)

摘要

The NIOSH analytical method S219 for determining nitroethane (79243) in air is described. Samples are adsorbed on XAD-2, desorbed with ethyl acetate, and analyzed by gas chromatography with a flame ionization detector. The working range of the method is 147 to 600 milligrams per cubic meter and the coefficient of variance is 0.06; the detection limit was not reported. Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations.
