METHOD AND SYSTEM FOR ANALYZING SOLID MATTER CONTAINING LIQUIDS AND MONITORING OR CONTROLLING PROCESSES CONTAINING SUCH LIQUIDS

摘要

The invention concerns a method and a device for analyzing a sample of industrial liquid containing solid matter. The sample is fractionated according to particle sizes and/or masses of the solid matter so as to produce sample fractions. A sample (30) is conducted to a disintegration channel (31) having depressions (31B). A liquid flow having a non-constant temporal velocity profile is applied through said disintegration channel (31), in order to gradually take solid matter of the sample with the liquid flow from said one or more depressions for providing said sample fractions. In one embodiment, the fractionation proceeds in a field flow fractionation (FFF) channel (33). From a homogenizer tube (35), which is an optional part, the fractionated sample is conducted via a conduit (36) to a measurement device (37) for measuring at least one physical or chemical property of at least one of said sample fractions.
