FIELD: methods of estimation of content of admixtures in gases by converting them in condensation nucleus followed by growing aerosol particles for estimation of content of admixtures by measurements of concentration of particles.
SUBSTANCE: proposed method includes converting admixture in condensation nucleus followed by coarsening of condensation nucleus for forming aerosol particles and measuring their concentration. Used as coarsening agent for estimation of aromatic compounds in gases is di-iso-butyl cebacate, diethyl cebacate or saturated hydrocarbons from tetradecane to heptadecane.
EFFECT: extended field of application; enhanced sensitivity.
