Development of a dedicated isotope mass spectrometer for the noninvasive diagnostics of humans infected with Helicobacter Pylori

A dedicated isotope mass spectrometer for the noninvasive diagnostics of humans infected with Helicobacter Pylori using the isotope respiratory test is developed. A low-aberration mass analyzer is calculated, an input system that makes it possible to eliminate the memory effects is developed, and a small-size ion detector is constructed. The mass spectrometer is created, and the tests are performed. The measurement accuracy of the $^{13}$С/$^{12}$С and $^{16}$O/$^{18}$O isotope ratios are 1.7 and 2.2$^{0}\!/{}_{00}$, respectively. Preliminary medical tests show that the spectrometer can be employed for the desired diagnostics.
