| Abstract: | Summary To determine toxic organic compounds (methanol, ethanol, n-propanol, acetone, methyl ethyl ketone, methyl isobutyl ketone)
in air a method was developed for their headspace gas chromatographic analysis with preconcentration in n-butanol (alcohols)
and in n-pentanol (ketones). The distribution coefficients of analytes in the air-absorbent system have been measured: 1051
(MeOH), 5630 (EtOH), 6773 (n-PrOH), 307 (Me2CO), 580 (MeCOEt), 1035 (MeCOBu-i). The minimum detectable level (mg m−3) was determined as low as 0.9 (MeOH), 4.0 (EtOH), 0.9 (n-PrOH), 0.2 (Me2CO), 0.1 (MeCOEt), 0.4 (MeCOBu-i). The method was effectively used for gas effluent air control in the workplace and in the
atmosphere.
