Abstract
A method for gas analysis includes the steps of extracting a gas sample from a gas to be analyzed with respect to one or more of its gas components, measuring the flow of the extracted gas sample, and adding a replacement gas to the gas in the same amount as the extracted sample in order to minimize the impact on the main gas flow of the extraction of the gas sample. The replacement gas can consist of the same gas components constituting the gas sample. A gas analyzer for performing the method is also disclosed.
