Abstract

The invention discloses a double-gas-path C13 infrared spectrometer. The double-gas-path C13 infrared spectrometer comprises a sample pool, infrared light sources and detectors. Collecting barrels aresymmetrically arranged in the sample pool, the interior of each collecting barrel is divided into a sample gas collecting area and a bottom gas collecting area through a partition plate, the sample gas collecting areas in the adjacent collecting barrels are communicated with each other, and the bottom gas collecting areas in the adjacent collecting barrels are communicated with each other. The infrared light sources are symmetrically arranged at ends of the collecting barrels. The detectors are symmetrically arranged at the other ends of the collecting barrels. The helicobacter pylori infection is judged by detecting the change of the ratio of the concentration of 3CO2 to the concentration of 12CO2.

Description

technical field [0001] The invention relates to the technical field of infrared spectrometers, in particular to a carbon-thirteen infrared spectrometer with two gas paths. Background technique [0002] A common method for detecting Helicobacter pylori in the human stomach is to administer 13 C-urea capsules, Helicobacter pylori will quickly decompose urea capsules into CO 2 , and excreted by lung exhalation, and taken by carbon-thirteen infrared spectrometer 13 C-urea capsules before and after 13 CO 2 and 12 CO 2 The ratio change of the concentration can be used to judge the infection of Helicobacter pylori. [0003] However, the existing infrared spectrometers need to be taken separately 13 The detection of exhaled gas from the lungs before and after C-urea capsules, so the instrument needs to carry out two detections. 13 C-urea capsules before exhaled gas detection, and then take 13 After the C-urea capsule is exhaled for detection, two detections are carried out ...
