Each tube has a single 600-mg 20/40 mesh section and a glass-fiber filter, the filter faces forward when sampling. SKC 226-183, or equivalent. Use an opaque tube holder or wrap tubes with aluminum foil or other opaque material while sampling. analytical solvent: (95:5) ethanol:water maximum volume: 9 Liters   minimum flow rate: 0.05 L/min for long-term sampling; 3 liters at 0.2 L/min for short-term sampling. current analytical method: Gas Chromatography; GC/FID method reference: OSHA SLTC In-House File method classification: Not Validated note: Separate the two tubes and cap both ends of each tube as soon as possible after sampling. Individually seal the two tubes. Protect tubes from light after sampling. Bulk method: GC/FID All Trademarks are the property of their respective owners.
