ANALYZER OF NATURAL GAS COMPOSITION Russian patent published in 2018 - IPC G01N21/65 G01N21/3504 

FIELD: measuring devices.

SUBSTANCE: invention relates to measurement equipment. Natural gas composition analyzer comprises a continuous laser, a focusing lens, a gas cuvette with an input and a side window, a photographic lens, a holographic filter, a spectral device coupled to a CCD array, and a control unit interacting with the CCD array. Additional window is placed in the cuvette, located opposite the window for the output of scattered radiation, in addition, a photographic lens, a holographic notch filter and a second spectral device coupled to its CCD array are additionally installed in the path of the scattered radiation light flux. One of the spectral instruments records radiation in the range 200–2,700 cm^-1, and the second – in the range of 3,400–3,800 cm^-1.

EFFECT: increase of reliability of gas analysis.
