Abstract
Fluorine analysis was examined by burning organofluorine compound in a quartz combustion tube, trapping the silicon tetrafluoride evolved in an absorption tube for carbon-hydrogen analysis, and calculating the amount of fluorine from increase in its weight. When a sample consists of carbon, hydrogen, oxygen, and fluorine, burning of the sample in nitrogen stream, using the apparatus for oxygen analysis, should produce carbon monoxide, hydrogen, and silicon tetrafluoride. Detailed examinations were made on this combustion gas and reagents capable of absorbing silicon tetrafluoride alone at ordinary temperature were examined.
