| Abstract: | The influence of gaseous hydrogen chloride on the efficiency and thermal stability of a Ucon LB-550-X stationary phase film has been studied under various working conditions. The efficiency of capillary columns was found to be unchanged or even increased, and the upper working temperature increased by 40–50°C. Nor did the action of hydrogen chloride change the polarity of the columns studied. |
