Pyrethrum analytical method.

Details

• Corporate Authors:
  National Institute for Occupational Safety and Health
• Description:
  The NIOSH analytical method S298 for determining pyrethrum (8003347) in air is described. Samples are collected on a glass filter, extracted with acetonitrile and analyzed by high performance liquid chromatography with an ultraviolet detector at 225 nanometers. The working range of the method is 1.413 to 8.47 milligrams per cubic meter, the coefficient of variance is 0.702, and the detection limit is about 1.0 microgram per milliliter for a 25 microliter injection. Analytical apparatus, reagents and procedures are described, and calculations are provided for determining sample concentrations. Data on particle size distribution, collection efficiency, and recovery and stability rates is included. [Description provided by NIOSH]
