Sample Gas Filters
The distance between the extraction point of sample gas and the analyser cabinet is normally bridged by tubes or hoses in continuous emission monitoring (CEM) systems. Depending on the method of analysis (FDIR, HFID, hot wet analysis, total hydrocarbons, etc.), these gas lines can be unheated or must be heated to prevent unwanted condensate formation.
Due to the nature of such installations, additional in-line filtration is required.
Bühler offers a wide selection of unheated and heated filters specifically designed for gas sampling applications.
