Principle of HCBT-01
CO2 has several characteristic absorption peaks in infrared band and there is a slight difference between the absorption peak positions of 13CO2 and 12CO2. By utilizing such slight difference, the HCBT-01 breath test analyzer is able to measure the concentrations of 13CO2 and 12CO2 respectively and then calculate the variation DOB (‰) of the abundance of 13C isotopes in the sample and baseline over the natural abundance of 13C, so as to determine whether the patient has been infected with H.Pylori.
