Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Polytetrafluoroethylene (FA) Filter (1.0 micron) in series with Tenax GC tube (60/30 mg sections)
    analytical solvent: Methanol
    maximum volume: 200 Liters
    maximum flow rate: 1.0 L/min
    current analytical method: High Performance Liquid Chromatography; HPLC/UV
    method reference: 2 (OSHA In-House File)
    method classification: Not Validated
    note: Immediately after sampling place front section of Tenax GC tube in vial with the Teflon filter. Seal and ship with backup section of Tenax GC tube.

Conditions: (Unknown whether 1 micron or .5 micron filter was used as the sampling media), Methanol extraction: C18 column; 55% methanol 45% water, PIC A; 1.9 mL/min; UV Det: 280, 229; Retention time, 6.5 min; C/P YC

Bulk Method:

  • Limit the amount of bulk submitted to one gram or one mL.
