Abstract

A method of analyzing a gaseous mixture comprising enclosing a volume of the mixture in an enclosure, cooling the enclosure to a temperature below the sublimation temperature of all bodies whose concentration is to be measured, and measuring, in the course of reheating of the enclosure, the amplitude of the abrupt elevations of pressure that accompany the passage from the solid state to the gaseous state of each body.
