Abstract

A determination of content of carbon and sulfur in organic and polymeric nonmetallic materials by method of combustion in an induction furnace of gas analyzer Leco CS-444 followed by detection in an infrared cell of spectrometer was investigated. A deter-mination of content of oxygen and hydrogen in organic and polymeric nonmetallic ma-terials by melting in inert gas were provided on TC-600 and RHEN 602 (Leco) gas an-alyzers followed by detection of oxygen in IR-cell of gas analyzer TC-600 and hydrogen in a conductance-measuring cell of RHEN 602 gas analyzer. In this paper we chose catalysts for complete extraction of these elements from organic and polymeric nonmet-allic materials. Accuracy and correctness of measurement results were confirmed by a good repeatability of the measured on gasanalyzes values of elements mass portion with their calculated values in the studied organic substances of the known molecular formula.
