This new apparatus (International patent Caprai-CNR pending no. PCT/IB2005/001568) for use in the analysis of gas mixtures can be fitted on one or more gas chromatographers working in parallel or at different times, and used to adjust the internal pressure of the gas to the value most convenient for introducing the sample into the analyzer. It can also be used for only one or two points of calibration of a pure gas standard (no preparation of a particular external standard is necessary). No detector overloading of any kind will occur.
Methods and apparatus for feeding samples of gas at controlled pressure into a gas chromatograph (international patent pending PCT/IB2005/001568) and its application to geochemical surveillance of reactive gas from Pozzuoli Solfatra (Naples, Italy).....
