摘要： 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.

摘要： The invention relates to a method for producing paper, board or the like. The method comprises obtaining a thick stock comprising cellulose fibres, forming a fibrous web and drying of drying the fibrous web. A strength agent system, which comprises at least one synthetic or natural polymer, or their mixture, and microfibrillated parenchymal cellulose material originating from non-wood sources, is added to the thick stock. The invention relates also to paper or board produced by the method.
