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.
