TDT Air Scan® is used to quickly and inexpensively identify what compounds are in the air. It utilizes Prism Analytical Technologies, Inc.'s (PATI) widest spectrum, multi-matrix thermal desorption tube that is designed to trap both polar and non-polar compounds. High Sensitivity Air Scan is especially useful for odor investigations since the odor threshold of many compounds is in the parts-per-trillion range. After sampling, the sorption tube is sent to PATI for the qualitative and quantitative identification of over 350 compounds. Other compounds which may be present can also be identified and semi--quantified. TDT Air Scan® is a combination of instrument technology and methodology developed by PATI that has a wide range of applications from personal monitoring, office buildings and warehouses to industrial complexes and landfills.Detection ranges from compounds like formaldehyde, propane, and the freons to 2-methylnaphthalene and tetradecane. Detection limits are in the 100 parts-per-trillion range. Sample collection requires a personal monitoring pump
