[Concentration of imidazolines in the air].
Using chamber for adjustable mode and dosing apparatus, the authors studied conditions of imidazolines' condensation from the air into 60% ethanol, to paper filters of "white tape" type, to analytic filters of AFA-HP type, into a shell with ultrathin layer of sorbent (2.7% sulfuric acid in 20% solution of glycerine in water). The best results were provided by experiments using the paper filter of "white tape" type and absorbing objects filled with 60% ethanol and containing spongy plate. Rate of the air pumping equalled 2-3 l/min and 0.5 l/min respectively.
