Trace Gas Analyser
The VeraSpec Trace is our uniquely selective and ultimate sensitivity trace gas analyser. The VeraSpec Trace is a truly innovative research grade instrument that takes the analytical capability of a number of Extrel’s best technologies for trace gas analysis, and makes them available for the first time in a single instrument;
- Atmospheric Pressure Ionization MS (APIMS)
- High sensitivity closed source electron impact ionization (EI)
- Membrane Inlet Mass Spectrometry (MIMS)
Atmospheric Pressure Ionization Mass Spectrometry (APIMS) has developed into a critical tool for pure gas analysis, providing part-per-trillion (ppt) level detection of certain impurities in pure gases.
For other impurities which are inaccessible by APIMS, high sensitivity electron impact ionization (EI) mass spectrometry can be used to supplement the analysis.
In other cases, membrane introduction mass spectrometry (MIMS) with the EI source can provide sub part-per-billion (ppb) detection limits for some components.
VeraSpec Trace has the unique capability to combine these techniques in a single instrument.
Each of the x3 VeraSpec Trace configurations is also available with MS/MS detector for accurate mass identification.
The table above shows the various possible ionization and inlet configuration options that are available, separately and in combination.
The table below is one example of the detection possibilities and details the detection levels for various compounds in bulk gas, measured for the first time on one instrument, the VeraSpec DS (dual source) from the table above.
