摘要:
The invention relates to a measuring cuvette in which a gas to be analysed by spectrometry is intended to circulate, the cuvette being in the form of a hollow tube (20) provided with a reflective material that forms an optical reflection layer, being characterized by the fact that: - the hollow tube (20) is made from a non-metallic material, - a removable soft optical article (1) is applied against the inner surface of the hollow tube (20), which article comprises a soft flexible support (10), one face of said support being covered with a reflective metallic material (11), said article being inserted into said tube so that said reflective metallic material forms the optical reflection layer.
