FIELD: process engineering.
SUBSTANCE: invention relates to techniques designed to determine and control inorganic and organic deposits in aqueous system, preferably, in circulating water systems incorporated with paper or cardboard production machines. Proposed method consists in placing one or more specimens into aqueous system and, preset time interval of exposure expired, removing it therefrom. Then specimens are prepared for surface analysis. Deposits formed on specimens are determined by microscopy, and/or gas/chromatography, and/or mass spectroscopy. Note here that spesimen(s) is (are) placed in additives containers, water spraying locations or an all damp places or those with higher moisture content.
EFFECT: higher validity of tested system state data.
