C13 carbon-13 breath analyzer manufacturer Helicobacter pylori detector

Schematic diagram and explanation of 13C detection process（C13 carbon-13 breath analyzer manufacturer Helicobacter pylori detector）：

a) The subjects should be fasted in the morning or for at least two hours.

b) The subject maintained normal exhalation by blowing gas into the airbag until it was full, and immediately tightening the airbag cover. This collected breath was taken for 0 minutes.

c) After taking one bottle of urea 13C granules with 80-100ml of cold drinking water, the subjects sit still.

d) The subjects collected their exhaled breath 30 minutes after taking urea 13C using the above method, and then tightened the airbag cover.

e) The collected exhaled gas bags at 0 and 30 minutes are sent to the infrared analysis component. The infrared detector converts the optical signal into an electrical signal, which is amplified and sent to the microcontroller and computer for data processing. The 13C/12C ratio and its changes in the gas at 0 and 30 minutes are calculated to obtain the change in 13C content.

f) Display the analysis results and print them.

C13 carbon-13 breath analyzer manufacturer Helicobacter pylori detectorBased on the above principle, it is used to qualitatively determine the Hp situation in the human body by detecting the difference in exhaled breath before and after taking the reagent in vitro.

The product mainly has the following technical features:
