Methods of processing and investigation of the possibilities of classification of mass spectra of exhaled gases

Analysis of exhaled air is one of the important areas of non-invasive medicine. As an example of the use of this method in scientific instrumentation, mathematical processing of mass spectra obtained on a quadrupole mass spectrometer MC7-200 is considered. The methods of data processing described on the basis of linear and quadratic discriminant analysis allow us to divide processed mass spectra of exhaled gases into two groups: mass spectra of exhaled gases of healthy people and mass spectra of exhaled gases of people with possible pathologies.
