    Abstract: An efficient absorption spectroscopy system is provided. The spectroscopy system may be configured to measure solid, liquid or gaseous samples. Vacuum ultra-violet wavelengths may be utilized. Some of the disclosed techniques can be used for detecting the presence of trace concentrations of gaseous species. A preferable gas flow cell is disclosed. Some of the disclosed techniques may be used with a gas chromatography system so as to detect and identify species eluted from the column. Some of the disclosed techniques may be used in conjunction with an electrospray interface and a liquid chromatography system so as to detect and identify gas phase ions of macromolecules produced from solution. Some of the disclosed techniques may be used to characterize chemical reactions. Some of the disclosed techniques may be used in conjunction with an ultra short-path length sample cell to measure liquids.

    Abstract: In one embodiment, an improved gas analysis system having a gas flow cell is provided. In another embodiment an improved gas flow cell is provided. As disclosed herein, dead volumes in a gas flow channel of a gas flow cell may be minimized through the use of one or more additional gas inlets. In one embodiment, an additional gas inlet is located between an analyte gas inlet and a light entrance optical coupling of the gas flow cell. In another embodiment, an additional gas inlet is located between an analyte gas outlet and a light exit optical coupling of the gas flow cell. In addition, enclosed regions may be formed adjacent seals of the gas flow channel of the gas flow cell. The enclosed regions may be evacuated and/or purged so as to minimize the passage of contaminants through the seals into the gas flow channel.
