The procedure for determination of gases and vapors with acidic properties (HF, HCl, HNO₃, NO₂, NO, H₃PO₄, SO₃, H₂SO₄, SO₂) using a portable single-column PIA-1000 and a stationary two-column LC-20 chromatographs (Shimadzu) was adapted to the analysis of atmospheric air of Krasnoyarsk city. The conditions for sampling and sample pretreatment of laboratory air sampling were optimized. The mobile-phase composition for increase of the selectivity of the determination of fluorine hydride  mixed formaldehyde and acetate acid’ vapors was proposal. The analysis of atmospheric air of Krasnoyarsk city was made.
