Abstract
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.
Claims7
A process for the determination and control of inorganic and/or organic deposits in an aqueous system, preferably a paper and/or board machine circulatory system, with one or more specimens being introduced into the aqueous system, said specimens being removed from the system after a preselected exposure period and prepared for a surface examination, characterized in that the deposits formed on the specimens are determined with microscopic methods and/or gas-chromatographic and/or mass-spectroscopic methods.
