Abstract: The invention concerns a method and system for analyzing a liquid sample containing solid matter. The method comprises fractionating the sample according to particle sizes and/or masses of the solid matter so as to produce sample fractions, and measuring at least one physical or chemical property of at least one of said sample fractions. According to the invention the sample is conducted to a disintegration channel having one or more depressions, and a liquid flow having a non-constant temporal velocity profile is applied through the disintegration channel, 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. The invention allows for efficient fractionation of samples, which cannot be fractionated using conventional field flow fractionation, for example.

Abstract: Method for detecting transparent exopolymer particles in a water sample. The method comprises step of obtaining a water sample and introducing a fluorochromatic reagent to the water sample. The fluorochromatic reagent is specific to vicinal hydroxide groups of transparent exopolymer particles, whereby the fluorescence signal of the reagent changes when it comes into contact with transparent exopolymer particles, i.e. TEP. Finally the fluorescence signal from the water sample is detected and the TEP level of the sample is determined.
