Abstract
A gas analyzing apparatus includes a sample gas line with a sample line valve for providing a sample gas, and a reference gas line with a reference line valve for providing a reference gas. A first gas analyzer is connected to the sample line downstream of the sample line valve, and a second gas analyzer is connected to both the sample and reference gas lines downstream of the valves. The lines are configured such that sample gas and reference gas may be alternately provided to the second gas analyzer either directly or indirectly via the first gas analyzer.
