ABSTRACT:
A gaseous stream of steam is analyzed for hydrogen sulfide by keeping the gas stream above its dew point while withdrawing a representative sample, mixing the sample with a gas having a dew point lower than that of the gaseous stream to form a mixture with a dew point below that of the gaseous stream, and analyzing the mixture at a temperature above its dew point for hydrogen sulfide.
