Abstract

La présente invention concerne un système (1) d'analyse de particules solides dans un milieu (2), comprenant un moyen d'illumination (3) apte à générer un champ lumineux (30) dans le milieu (2), un moyen de piégeage (4) d'au moins une partie (30') du champ lumineux (30) généré et disposé dans la direction (31) dudit champ lumineux (30), et un moyen principal de détection (5) du champ lumineux (30") diffusé par lesdites particules solides dans ledit milieu (2). Dans ce système, le moyen principal de détection (5) comprend un photodétecteur (52) du champ lumineux (30") diffusé par les particules solides dans le milieu (2) et un compteur (53) de ces particules solides dans ce milieu (2), ce moyen principal de détection (5) étant orienté dans une direction (51) formant un angle (α) sensiblement compris entre 10° et 20° par rapport à la direction (31) du champ lumineux (30) généré. La présente invention concerne également un procédé d'analyse de particules solides dans un milieu (2) mettant en œuvre un tel système (1) d'analyse.
