ScanWave
With its unique collision cell, Xevo TQ enables you to better address your analytical needs with the option to operate in a new ScanWave enhanced product ion scanning mode. In this mode, ions are accumulated and then separated according to their mass-to-charge ratio (m/z). Synchronizing the release of these ions with the scanning of the second quadrupole mass analyzer significantly enhances the signal intensity of full scan product ion spectra. Simply put, this enables you to more easily confirm the identities and structures of your analytes of interest.
Xevo TQ is capable of the highest MRM data acquisition rates without significant losses in signal. This ensures the very best MRM quantification data for your demanding, high speed, and high resolution UPLC/MS/MS assays.
RADAR
You no longer have to accept the complications and uncertainty associated with matrix effects. When performing targeted quantification, RADAR allows you to see the whole picture, and have total confidence.
In RADAR mode, you can monitor for matrix interferences, metabolites, impurities, and degradants in your sample while accurately quantifying your target compounds.
With RADAR you can collect data in both multiple reaction monitoring (MRM) and full scan spectral acquisition modes at the same time. In addition, RADAR mode acquires all detectable ions in both positive and negative full scan MS, arming you with a depth of knowledge about your sample not previously possible from a traditional quantitative assay. RADAR is only possible because of the ability to rapidly alternate between MS, MS/MS, positive, and negative ion modes without compromising performance in any mode.
Ion Source Options
The universal ion source architecture of Xevo TQ allows the widest range of ionization techniques to be utilized as well as the very latest innovations in ionization technologies. So you'll have limitless choice in experimental options.
When you need options and time is critical, the ion sources are quickly interchangeable and ready to use within minutes.
