Acetaldehyde Analytical Method.
NIOSH 1979 Mar:25 pages
The NIOSH analytical method S345 for determining acetaldehyde (75070) in air is described. Samples are collected in a midget bubbler, derivatized with Girard-T reagent, and analyzed by high pressure liquid chromatography. The working range of the method is 170 to 670 milligrams per cubic meter, the coefficient of variance is 0.053, and the detection limit is less than 0.1 milligram per sample. Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations. Data on collection efficiency, and recovery and stability rates is included.
