Abstract
A method for preparing a test gas stream for a gas analyzer in which test gas is drawn from a test gas stream by a test gas probe, conducted through a test gas tube to a condensate separator, and then analyzed in the gas analyzer for certain components such as NO.sub.2 and SO.sub.2 for example, with the average flow rate of the test gas stream in the test gas tube being set to a value of at least 1.5 m/s.
