Title
(EN) MULTIPASS CELL AND ANALYSIS METHOD
(FR) CELLULE MULTIPASSAGES ET PROCEDE D'ANALYSE
Abstract
(EN)
A multipass cell (1) for optical analyses, such as spectrometry, of a fluid; the cell comprises a plurality of mirror means (20) each having an essentially planar light-reflecting mirror face (210); the mirror means are arranged in an essentially circular pattern having a center (P); the planar mirror faces (210) are facing the center of cell (1).
(FR)
Cette cellule multipassages (1), du type spectromètre, destinée à des analyses optiques d'un fluide, comprend une pluralité de miroirs (20) présentant chacun une face (210) réfléchissante et essentiellement plane. Ces miroirs sont disposés en un arrangement essentiellement circulaire présentant un centre (P), les faces (210) planes étant situées en regard du centre de la cellule (1).
