AI Technical Summary
Technical Problem
In existing technologies, the sampling circuit is easily contaminated, leading to inaccurate measurement results from the gas analyzer, and the contamination detection is not systematic, usually only being discovered during the data interpretation process.
Method used
The sampling loop design, which includes valves, allows switching between sample analysis and contaminant analysis operations. It also monitors contamination through purge fluid detection and analyzer computing equipment, and adjusts measurement settings to compensate for contamination.
Benefits of technology
It enables accurate and reliable gas analysis of the sampling loop, reduces inaccurate measurements, and improves data reliability and real-time detection capabilities.

Abstract
Provided herein are gas analysis systems including a sampling circuit and a gas analyzer operable to measure a gas flowing through the sampling circuit. A purge fluid can be directed through the sampling circuit and measured by the gas analyzer to detect contamination in the sampling circuit. An operator and / or a controller can take one or more remedial actions in response to the detected contamination in the sampling circuit to improve reliability, accuracy, and / or longevity of the gas analysis system.
