Tiivistelmä
The aim of this study was to implement and validate Gasmet DX-4000N on-site Fourier transform infrared (FTIR) gas analyser for measuring volatile organic compounds (VOCs). The implementation of the analyser was part of the project ODORA (Abatement of odorous and harmful emission gases).
To assess the detection limits and the accuracy of the analyser, laboratory comparison tests were conducted in prior to field measurements. Comparison tests were performed with a reference FTIR analyser. No significant differences were found in results between the two analysers.
In order to verify the analyser's results, comparisons with another analysing method were performed. During a field measurement, reference samples were collected into adsorption tubes. The tubes were analysed in laboratory and the results were found to be comparable. The adsorption tube results verified that the measured concentrations were extremely low.
On-site Gasmet FTIR gas analyser was found to be easy to use, exact and steady measuring device in field conditions. It was proven to be an ideal tool for measuring multicomponent gas samples even in hot, wet and corrosive gas streams. Even at low concentrations the comparison measurements showed no significant differences.
