SIFT-MS
Overview
SIFT-MS (Selected Ion Flow Tube Mass Spectrometery) provides the capability of
the quantitative measurement of VOC's in the gas phase at sub-ppb concentrations
without calibration. Other techniques are limited to a single ionisation process
or reagent, making the
interpretation of results more difficult and subjective. With
a user-specified choice of reagent ions SIFT-MS not only
incorporates ionisation by proton transfer but also charge
transfer, hydride ion transfer and three-body association.
This provides the facility to cross-reference results,
enabling more certain identification of unknown peaks in complex mass spectra.
 
Profile 3
Applications for trace gas measurement are varied and
challenging and growing in number every day. Quantitative
analysis of real samples has always been a problem,
particularly moist samples, such as exhaled breath.
Now, the Profile 3, from Instrument Science, provides
solutions not available elsewhere. Gas phase samples can be
analysed down to single digit ppb levels, without pre-concentration.
The breath from a patient, the atmosphere in a
workplace or the exhaust from an engine can be sampled
directly, providing immediate results. Volatile liquids can also
be analysed via their headspace.
