Failure Report No. S305.
NIOSH 1979 Feb:31 pages
The NIOSH analytical method S305 for determining tetraethyl- pyrophosphate (107493) in air is described. Samples are adsorbed on Chromosorb-102, desorbed with toluene and analyzed by gas chromatography with a flame photometric detector. The working range of the method is 0.025 to 0.102 milligrams per cubic meter, the coefficient of variance is 0.086, and the detection limit is about procedures are described, and calculations are provided for determining sample concentrations. Data on desorption efficiency, collection efficiency, and recovery, stability and breakthrough rates is included. The method was unsatisfactory because the accuracy could not be adequately determined.
