摘要：
A technique for refractometric determination of microquantitites of hydrogen chloride in the gas phase of an excimer Xe-laser based on the change in the refractive indices of highly concentrated NaOH solutions upon introducing small amounts of HCl in them is suggested. The detection limit is 0.3 mu g, and the minimum concentration determined is 3 x 10(-5) wt.% HCl. The duration of the analysis is 5 - 7 min.
