Innovative Multi-Mode Vapor Thermal Desorption Devices


Keywords: , , , ,

Use of thermal desorption techniques is an established method for environmental and industrial hygiene studies of noxious vapors and their effects on health. Utility of the thermal desorption technique, however, has been hampered by rudimentary sampling equipment. With the improvements in recent years of electronic controls, Seacoast Science has designed, fabricated and lab-tested an innovative vapor sampler to assist in quantifying toxic industrial chemicals (TIC’s) in the workplace. The samplers consist of multi-bank, multi-tube, individually addressable tube, sequential air-sampler modules. Air sampling campaigns are programmed into the modules using the on- board user interface, or uploaded from a computer via USB connection. The design objective was a readily transportable air sampler that allows the users to capture air samples using COTS thermal desorption tubes.
