Demeton Analytical Method.
NIOSH 1979 Aug:36 pages
The NIOSH analytical method S280 for determining demeton (8065483) in air is described. Samples are collected on mixed cellulose ester filters and XAD-2 (9060053) sorbent, desorbed with toluene (108883), and analyzed by gas chromatography with a flame photometric detector. The working range of the method is 0.06 to 0.33 milligrams per cubic meter, the coefficient of variance is 0.08, and the detection limit is 0.1 microgram per sample. Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations. Data on recovery, stability and breakthrough rates, and desorption efficiency is included.
