SORBENT TUBE, XAD-7, 6X70, 60/30, 50/BX

For measuring the air concentration of chemicals including cresol, phenol, pyridine and tetraethyltin.

Description

These tubes are used to measure the average concentration of potentially harmful vapors in the air over a defined sample period. To use, the tube is connected to a small vacuum pump that draws air through the tube at a precise flow rate over a period of time. After the sample is taken, the tube is transported to a laboratory where they can remove the adsorbent material and perform analysis by solvent extraction and gas chromatography (GC) to determine the quantity of chemical collected, from which a time-weighted average (TWA) concentration can be calculated.
