For a quick analysis of simple mixtures of lower chlorinated hydrocarbons a possible application has been studied of short glass micro-packed columns packed with commercial sorbents for extraction by solid phase. For analyses of lower alcohols, carboxylic acids, and other oxygen-containing substances the columns were packed with the organic porous sorbent, a copolymer of divinylbenzene and 1,4-di(methacryloyloxymethyl)naphthalene. The chosen sorbents were placed into glass capillary columns of 0.4 - 0.7 m length and 0.7 mm i.d. As the sorbent amount in the column is small, the columns are cheap. Whenever necessary, they can be prepared in any laboratory. The analyses of simple mixtures of above-mentioned classes of compounds lasted from 90 to 270 s.
