Abstract: The present invention discloses a method and a system for monitoring condition of a sample handling system connected to a gas analyzer. The sample handling system comprises a sample line for supplying a gas sample to the gas analyzer, and sample handling devices. The system for monitoring condition, receives measurements from temperature and pressure sensors connected to the sample line and obtains operating characteristics of the sample handling devices based on the measurements and model of the sample handling system; and determines the condition of the sample handling system based on comparison of the operating characteristics of the sample handling device against a plurality of reference values associated with the sample handling device.
