Analyser Helps Protect Safety of Compressed Air

An advanced multiparameter gas analysis technology (FTIR) from Quantitech (UK) is being employed by Case Chemicals to analyse compressed air for recreational, commercial and military divers. According to Case’s Sam Wray, “This technology provides much higher levels of confidence than traditional techniques, partly because it is highly accurate and also because FTIR can detect almost any gas or vapour.”

The FTIR analyser employed by Case Chemicals was supplied by Quantitech’s Dr Andrew Hobson who pre-configured the analyser (a Gasmet DX4030) to measure a wide range of parameters including CO, CO2, hydrocarbons, NH3, HCl, HF, NO2, N2O, SO2 and a range of halocarbons such as Freon.

Sam Wray says, “In the past, some of our clients have used chemical stain tubes which can have an error of up to 30%, so whilst these are individually cheap, they are highly inaccurate in comparison with FTIR and only test for one gas.”
