Abstract

An object of the invention is a system for supervising a measuring instrument system and protecting it from the influence of unwanted moisture. It is especially useful during continuous pCO2/CH4 measurements using the full equilibration method, combined analyzers working in a vacuum. Before this invention to detect water that may accidentally enter the analyzer, usually, two electrodes were used and the closed-circuit signalised the entering of liquid water. Our device uses an electric field for detection and signalises not only the presence of water in the liquid phase but also the excess of unfavourable water in the gas phase. Our protection system also does not suddenly turning off the analyzer after detecting water but allows the analyzer to keep on working but in safe conditions.
