Title: Arrangement for connecting a low-pressure inlet of a gas analyzer

Abstract: Arrangement and method for connecting a low-pressure connection of a gas analyzer with a test gas connection operated at a higher pressure level includes a connection line with a connection for the low-pressure connection and a connection for the test gas connection. A gas flow connection leads into the connection line, and a valve body is configured to be operable in the connection line for controlling a gas flow cross-section thereof for the connection to the low-pressure connection. The valve body is guided within a line section connected with the connection line on the gas flow connection, and the gas flow cross-section is formed between an interior wall thereof and the valve body.
