Abstract (en)

[origin: WO2006097321A1] The invention relates to a method for determining and controlling inorganic and/or organic deposits in a water system, preferably a paper and/or board machine re-circulation system. According to said method, one or more probes are introduced into the water system, then removed from said system after a pre-selected exposure period and prepared for surface analysis. The deposits that have accumulated on the probes are determined by means of microscopy methods and/or gas chromatography methods and/or mass spectrometry methods.
