SAMPLING: 1.
Calibrate each personal sampling pump with a representative sampler in line. 2. Assemble the sampler and connect the sorbent tube (ends broken just before the connection) to the sampling pump with backup section nearest the sampling pump. Keep the sampler in a vertical position during sampling. 3. Sample at an accurately known flow rate between 0.5 and 1 L/min for a total sample size of 10 to 200 L. 4. Remove the sorbent tube from the outlet of the cassette and connect it to the inlet side of the cassette. ”

“ Sampler: 37-mm, 0.8-μm pore size cellulose ester membrane filter supported by a stainless steel screen in a two-piece filter cassette holder plus a 10 cm x 8-mm OD x 6-mm ID, 20/40 Chromosorb 102 tube (front = 100 mg; back = 50 mg) , separated by 3-mm silanized glass wool plug, flame sealed ends with plastic caps. Pressure drop across the tube at 1 L/min must not exceed 2.5 mm Hg. Filters and tubes are commercially available. 2. Personal sampling pump, 0.5 to 1 L/min, with flexible connecting tubing. 3. ”
