Silver Analytical Method.
NIOSH 1978 Jun:28 pages
The NIOSH analytical method S182 for determining metal and soluble silver (7440224) compounds in air is described. Samples are collected in a mixed cellulose ester membrane filter and analyzed by emission spectroscopy with a direct current plasma excitation source. The working range of the method is 0.0036 to 0.0181 milligrams per cubic meter, the coefficient of variance is 0.7, and the detection limit is about 0.0002 milligrams per cubic meter for a 180 liter sample. Analytical apparatus, reagents and solutions are described. Calculations are provided for determining sample concentrations. Data on recovery and stability rates is included.
