Monitoring Methods used by OSHA

Primary Laboratory Sampling/Analytical Method (SLC1):

  • sampling media: Glass Fiber Filter (37 mm)
    analytical solvent: (1:1) Methanol/Water
    maximum volume: 100 Liters
    maximum flow rate: 1.0 L/min
    current analytical method: High Performance Liquid Chromatography; HPLC/UV/VIS
    method reference: 2 (OSHA In-House File)
    method classification: Partially Validated

Conditions:

  • 50% methanol/50% water extraction; Zorbax ODS; 55% methanol 45% water; 0.005 M TBAP; 1 mL/min; UV/VIS 650; Retention time, 7.8 min; DL 0.83 ng/inj; C/P YC 1/82
