Gas Analysis
Gas Analysis is a much more involved process when compared to Residual Gas Analysis. The objective is to 'quantitatively' analyze a Gas Sample to determine the gas mix rather than provide a 'qualitative' overview. This may be to determine the progress or outcome of a process which is dependant upon gas mix, perhaps to provide some element of control to a process or for QA purposes proving that a product is within tolerances.
Whatever the reason, to determine 'quantities' of material with the required accuracy adds a number of significant steps to the measurement process. Instrument stability and accuracy together with software capability also become more critical.
A determination needs to be made of "What is sample and what was in the system before the sample was introduced?" referred to as background. Consideration needs to be made of the differing response all mass spectrometers will have to different materials. For accurate results, the system will need to be calibrated with known levels for reference during the calculation to turn detected ion currents into measured values (for example - percent or ppm).
The Odyssey provides the stable, accurate measurement capability needed and the VTI range of calibrated leaks can be used to provide the reference calibration needed. Software routines then take care of the necessary steps needed to perform accurate gas analysis on repeatable basis.
