Abstract
The results of the comparative analysis of exhaled air samples from patients with diabetes mellitus second type (target group) and healthy volunteers (control group) with using laser optical-acoustic IR spectroscopy are presented. The measured absorption spectra of exhaled air samples visualization were performed using the principal component analysis. The good spatial separation of the target and control groups in the space of the main components was achieved, which indicates a significant change in the composition and concentration of metabolites in the exhaled air of patients with diabetes. The volatile metabolites that may be characteristic of diabetes are also discussed.
