Ten NIOSH (National Institute for Occupational Safety and Health) Analytical Methods - Phosphine

摘要

The NIOSH validated method for the determination of phosphine (12768820) is described. The absorbance of the solution is immediately measured at the wavelength of 625 nanometers. The concentration is determined from a calibration curve. The method is validated for phosphine concentrations of 0.195 to 0.877 milligrams per cubic meter (mg/cu m), with a standard deviation of 0.0119mg/cu m.
