Sorbent tube sampling is the NIOSH/OSHA/EPA approved method for collecting most hazardous gases and vapors from the air. A sample is collected by opening a tube, connecting it to a sample pump, and pulling air through the tube with the pump. Airborne chemicals are trapped onto the surface of the sorbent. The tube is extracted using solvents or heat. The sample extracted from the tube is analyzed to determine the amount of chemical hazard present. Tubes produced by SKC company excel good-quality with reproducible recoveries and low standard deviation. SKC offers a complete line of tubes for occupational and environmental methods.
