Monitoring Methods used by OSHA
Primary Laboratory Sampling/Analytical Method (SLC1):
- Tared Polytetrafluoroethylene (PTFE) filter, 2 µm, 37 mm
- maximum volume: 960 Liters
- maximum flow rate: 2.0 L/min
- current analytical method: Gravimetric / Benzene Solubles / High Performance Liquid Chromatography; HPLC/UV/FLU
- method reference: NIOSH Analytical Method (NIOSH 5042 (PDF))
- method classification: Partially Validated
- note: OSHA personnel must obtain tared PTFE filters from the Salt Lake Technical Center. The sample will be weighed and the concentration of the collected material determined. If the concentration is over 0.4 mg/m3, the filter will be extracted with benzene to determine the concentration of the soluble material.
Wipe Sampling Method:
- Glass Fiber Filter
- analytical solvent: Dry
- Limit the amount of bulk submitted to one gram or one mL.
