Nitromethane Analytical Method.
NIOSH 1979 Jan:23 pages
The NIOSH analytical method S220 for determining nitromethane (75525) in air is described. Samples are adsorbed on Chromosorb- 106, desorbed with ethyl-acetate (141786), and analyzed by gas chromatography with an alkali flame ionization detector. The working range of the method is 123 to 501 milligrams per cubic meter, and the coefficient of variance is 0.078; the detection limit was not determined. Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations. Data on recovery, stability and breakthrough rates is included.
