The invention relates to a method of and equipment for preparing an analysis sample (2) for a continuous on-line analysis. According to the invention, a sam-ple material (5) is taken by means of a sampling ar-rangement (4) from a material flow (24) that contains solid matter and liquid, whereby the sample material (5) is fed into a chamber (6); a layer of material (10), which contains coarse solid matter, depositing in the lower part of the chamber, and a layer of material (8), which contains liquid and fine solids, being sepa-rated from the sample material in the upper part of the chamber, whereby at least part of the material (8), which contains fine solids, is moved to the lower part (9) of the chamber (6), from where the analysis sample (2) that has a higher solids content than the sample material (5) is removed.

L'invention concerne un procédé et un équipement pour préparer un échantillon d'analyse (2) pour une analyse en ligne continue. Selon l'invention, un échantillon (5) est pris au moyen d'un agencement d'échantillonnage (4) à partir d'un flux de matière (24) qui contient une substance solide et un liquide, l'échantillon (5) étant introduit dans une chambre (6) ; une couche de matière (10), qui contient une substance solide grossière, se déposant dans la partie inférieure de la chambre, et une couche de matière (8), qui contient un liquide et des corps fins, sont séparées de l'échantillon dans la partie supérieure de la chambre, au moins une partie de la matière (8), qui contient des corps fins, étant déplacée vers la partie inférieure (9) de la chambre (6), d'où l'échantillon d'analyse (2) qui a un contenu en solides supérieur à celui de la matière d'échantillon (5) est enlevé.
