In order to ensure that a sample can be taken continuously from a reaction chamber with a minimum of maintenance work, the sample gas is extracted from the reaction chamber in two identical extraction lines in alternation and at a rate which exceeds the rate required for the analysis and surplus gas which has been extracted by one extraction line is branched from the sample gas and is blown back to the reaction chamber through the other extraction line.

In a method of continuously taking hot sample gas from a reaction chamber and for delivering said sample gas at a predetermined rate to an analyzer wherein said sample gas is conducted in an extracting direction in an extraction line comprising an extraction probe and filter means downstream of said probe, the improvement residing in the gas is extracted from said reaction chamber at a rate in excess of said predetermined rate through two identical extraction lines in alternation, each of which extraction lines contains an extraction probe and filter means downstream of said probe, and surplus gas in one of said extraction lines in excess of said predetermined rate is diverted from said sample gas downstream of said filter means in said one extraction line and is blown back into the reaction chamber through the other extraction line in a direction which is opposite to said extracting direction.
