Abstract
A heat treatment device for the conversion of gaseous test samples into constituents determinable by a detector provides the possibility of obtaining the desired pyrolysis products even during the sampling, then feeding them directly to the detector. The device has a small structural shape, and is able to be carried and used easily and operated independently of an external energy supply. The heat treatment device is connectable to a number of different detectors. A container 1 through which the test gas can flow is provided with a chemical filler 5, 7, 8 capable of an exothermic reaction, and with a starter 4 initiating the reaction.
