Breath analysis using cavity ring down spectroscopy in UV region for diagnostics of diabetes

In our work, we demonstrate the current results of acetone measurements in exhaled breath using cavity ring down spectrometry for diagnostics of diabetes and other diseases. Our cavity ring down spectrometer is a portable system that works in UV region with the pulsed Nd:YAG laser at 266 nm. Calibration of the system was performed using generated samples by KinTek automated permeation tube system, both, self-prepared and commercial mixtures with known concentration acetone samples in air. In this experiment, we examined breath samples from healthy volunteers and some persons with diabetes before medical treatment.
