Industrial evaluation of "Hygitest" detector tubes for ethyl acetate.

Abstract

"Hygitest" detector tubes for ethyl acetate based on a silica gel carrier treated with an indicator reagent--chromium-sulphuric acid were developed. Their quality parameters were compared with the characteristics of the detector tubes for ethyl acetate produced by other companies. An evaluation of the developed detector tubes in industrial atmosphere was carried out. The results obtained are discussed in view of the non-specificity of the detector tubes proposed.
