The instrument features optimised resolution, enhanced ion optics for the highest sensitivity, a quadrupole mass filter and a collision cell for MS/MS analyses. This powerful combination delivers simple exact mass measurement of precursor and fragment ions with maximum sensitivity to yield the highest confidence in structural elucidation and databank search results.The Ultimate in MS and MS/MS Performance
The Micromass Q-Tof API-US provides enhanced resolution and sensitivity with all the benefits of exact mass measurement in MS and MS/MS. These features are also accessible over an enhanced linear dynamic range, enabling rapid and reliable quantification. In combination these features provide the highest quality information on elemental composition, structural characteristics and unsurpassed specificity for identifying and characterising even the lowest abundance compounds in complex matrices.
Why Exact Mass MS & MS/MS?
So, do you really know the mass of your compound? Are you confident that you’ve identified the correct component? As with every analytical tool, the more accurately you make your measurement the more confidence you'll have in your results. Exact mass measurement enables you to determine the elemental composition of compounds with greater confidence. When you detect a drug metabolite at 500.2 m/z in an in vivo sample, are you sure which bio-transformation has taken place? When you detect a peptide at 976.6 m/z, can you be sure which posttranslational modification is present?
With exact mass measurement you can:
- Determine elemental composition
- Distinguish nominally isobaric components
- Improve specificity of detection for MS/MS analyses
- Improve data processing speed and specificity
Why Exact Mass MS/MS?
Exact mass measurement becomes an increasingly powerful tool for determining elemental composition at lower m/z values, and is therefore particularly useful for identification of fragment ions in MS/MS. With the increased accuracy of exact mass measurement, peptide sequencing and the elucidation of small molecule structures is significantly enhanced. Data processing tools for automated interpretation rely heavily on the specificity of exact mass measurements.
With exact mass MS/MS you can:
- Eliminate false positive protein ID's apparent in nominal mass data
- De novo sequence peptides with the highest level of confidence
- Identify elemental composition of structural fragments
- Gain excellent specificity for quantitative analyses
