The article presents the optimization method of reception exhaled air condensate (EAC) for LCS-researching. The device for collecting EAC is offered. The methodic is presented which can with using this device quickly receive surveying condensate volumes in the quantity necessary for LCS-researching. It is shown that the prevailing contribution in light dispersion particles in diameter of 2 nm, 15–20 nm and 120–210 nm is traced in the generalised LC-spectrum of healthy people’ surveyed group. Statistics fluctuations testify to an insignificant dispersion of the received values. The variation factor of the LC-spectrum indicators majority fluctuates within 10%. The offered way can be used under conditions of ambulance stations and hospitals, and also at dispancer inspections.
