Abstract
A measuring vessel in which a gas to be analyzed by spectrometry is intended to flow, the vessel being in the form of a hollow tube provided with a reflective material forming an optical-reflection layer, including: a hollow tube is produced from a non-metallic material, and a removable supple optical article is applied against the internal surface of the hollow tube, the article including a supple flexible support, one face of the support being covered with a reflective metal material, the article being inserted in the tube so that the reflective metal material forms the optical-reflection layer.

A measuring vessel in which a gas to be analyzed by spectrometry is intended to flow, the vessel being in the form of a hollow tube provided with a reflective material forming an optical-reflection layer, wherein the hollow tube is produced from a non-metallic material,
- a removable supple optical article is applied against the internal surface of the hollow tube, said article comprising a supple flexible support, one face of said support being covered with a reflective metal material, said article being inserted in said tube so that said reflective metal material forms the optical-reflection layer.
A method for manufacturing a measuring vessel in which a gas to be analyzed by spectrometry is intended to flow, the vessel being in the form of a hollow tube provided with a reflective material forming an optical-reflection layer, characterized by the fact that the method comprising:
- i) producing the hollow tube from a non-metallic material;
- and
- ii) applying against the internal surface of the hollow tube:
- a removable supple optical article, said article comprising a supple flexible support, one face of said support being covered with a reflective metal material, said article being positioned in said tube so that said reflective metal material of said article forms the optical-reflection layer.
A method for producing an electromagnetic barrier in a measuring vessel in which a gas to be analyzed by spectrometry is intended to flow, the vessel being in the form of a hollow tube provided with a reflective material forming an optical-reflection layer, said tube being produced from a non-metallic material, the method comprising:
- applying against the internal surface of the hollow tube:
- a removable supple optical article, said article comprising a supple flexible support, one face of said support being covered with a reflective metal material, said article being positioned in said tube so that the reflective metal material forms the optical-reflection layer and forms an electromagnetic barrier between the inside of the vessel and the internal surface of said tube.
