A gas sampling apparatus includes a probe tube having a tip positionable in a stream of products of combustion and a sample dryer tube connected in fluid communication with an end of the probe tube opposite the tip. The sample dryer tube is received in a purge gas tube along a lengthwise axis thereof. The purge gas tube and the sample dryer tube define therebetween a space through which a purge gas pump urges a purge gas in a first direction. A sample pump connected in fluid communication with the sample dryer tube urges therethrough in a second direction opposite the first direction a sample of gas obtained from the stream of products of combustion via the probe tube. A purge gas tube heater is positioned adjacent an end of the sample dryer tube which receives the sample of gas therein. The purge gas tube heater maintains the temperature of the sample of gas received in the sample dryer tube above the dew point temperature of water in the sample of gas. A sensor is positioned to detect a constituent of the sample of gas exhausted from the sample dryer tube. The sample dryer tube is formed at least in part of a hydrophilic membrane and the purge gas entering the space contains less water vapor than the sample of gas. Water vapor contained in the sample of gas is conveyed through the hydrophilic membrane part of the sample dryer tube to the purge gas flowing in the space so that the purge gas exhausted from the space contains more water vapor than the purge gas entering the space and the sample of gas exhausted from the sample dryer tube contains less water vapor than the sample of gas entering the sample dryer tube.
