MEASURING CUVETTE FOR SPECTROMETRIC MEASURING INSTRUMENT

摘要

The invention relates to a measuring cell suitable for analyzing by spectrometry a gas circulating in the cell, the cell comprising a hollow tube comprising an internal surface and a reflective material forming an optical reflection layer and a removable flexible optical article applied against the surface. internal hollow tube. The hollow tube is made of a non-metallic material and the optical article includes a flexible flexible support. One side of the support is covered with a reflective metallic material and the optical article is inserted into the hollow tube so that the reflective metallic material forms the optical reflection layer. It is thus possible to reduce the effects of external electromagnetic fields without affecting the optical reflection properties.
