Acquired in 2020, the new Waters Synapt G2-Si ESI MS allows us to expand our service to include ion mobility analysis, in addition to the high resolution, HD-MRM and HD-DDA analyses we provide currently. Sometimes chromatography and mass resolution are not enough. With high-efficiency T-Wave ion mobility, an additional dimension of separation is available based on molecular size and shape. The unique ability to use the collision cross section property of a molecule delivers the highest levels of selectivity, specificity, sensitivity and structural insight. The wide range of benefits feature isomer separation, elimination of interferences, generation of cleaner spectra and even the ability to better confirm compound ID.
