Details

• Corporate Authors:
  National Institute for Occupational Safety and Health
• Description:
  The NIOSH analytical method S294 for determining paraquat (1910425) in air is described. Samples are collected on a polytetrafluoroethylene filter, extracted with water, and analyzed by high performance liquid chromatography with an ultraviolet detector at 254 nanometers. The working range of the method is variance is 0.088, and the detection limit is 2.0 micrograms per milliliter for a 20 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]
