    dilution extractive sampling gas analysis
    en
    Definition analysis of a process gas during which a very small representative portion of a gas stream is extracted and the sample is very accurately diluted with air before transportation to an analyser Reference "COM-EN, based on:Darrell Leetham. Breath Easy. SEPTEMBER 2005 ICR http://www.thermo.fr/eThermo/CMA/PDFs/Various/File_27068.pdf [1.12.2011]"
    Comment There are two basic ways to dilute an extracted sample. One technique for diluting the gas sample takes place within the sample probe itself. In other words the dilution mechanism is part of the probe. This is termed 'in-stack dilution'. The other technique for dilution takes place immediately after the probe right at it’s discharge. This is termed “out of stack dilution”
