Many times the source of an air problem can be the off-gassing of a product. Whether the product is feed to a secondary process or the use of the product creates certain off-gassing, Prism can assist your staff with the determination of compounds.

AS004-HS — A full spectrum of compounds is determined in the product/material off gas using a combination of Fourier Transform Infrared (FTIR) and Gas Chromatography-Mass Spectrometry (GC-MS). These include organic and inorganic compounds from methane and ammonia to C14 and methylnaphthalene (one of the diesel markers). The analysis depending on the instrumentation employed includes up to 400 compounds like halogenates, alcohols, aldehydes, ketones, primary hydrocarbons, aromatics, and petroleum aromatics as well as inorganics like SO_X, NO_X, CO_X, HCl, HF, HBr, methane, water, ammonia, and fluorinated compounds typically associated with the semiconductor industry. This analysis is primarily designed to identify volatiles off-gassed from solid and semi-solid materials.

Off-gas can be determined as either partial or total off-gas and either at one temperature or multiple temperatures. For IR-active compounds, a 10-second time interval between samplings is available for off-gas time resolved studies. Generally, a discussion with the technical staff at Prism Analytical Technologies is recommended before sampling commences.
