Hydrocarbons and other impurities in calibration and specialty gases


Calibration gas mixtures for analytical purposes and specialty gases for medical applications are routinely tested for impurities during the quality control process. Usually this is done by an array of gas chromatographs equipped with different detectors. These techniques take an average of at least 20 minutes to provide a result. On-line mass spectrometry can significantly speed up this process.


V&F's AirSense mass spectrometer can perform an analysis of impurities in calibration gas mixtures in less than one second. This applies not only to organic compounds, but also to inorganic substances. The Ion Molecular Reaction technology (IMR) convinces with its sensitivity and selectivity. Detection limits for typical impurities in calibration gases are in the lower ppb range. V&F mass spectrometers can be equipped with a variety of interfaces to ensure good integration into the process control environment. In addition, certificates can also be printed.

V&F on-line mass spectrometers provide real-time results. Technologies based on gas chromatography take several minutes for a measurement, and multiple instruments are needed to determine the compounds that an AirSense IMR-MS measures in a single setup. V&F mass spectrometers enable technicians to quickly adapt the instrument to new measurement routines or expand the current measurement setup by adding new compounds of interest. A compact design supports mobility, and changing the measurement location can be done effortlessly within one business day.
