Waters Xevo G2-XS QTof and Xevo TQ-S micro mass spectrometers

Waters has introduced the Xevo G2-XS mass spectrometer, a high-performance benchtop quadrupole time-of-flight (QTofTM) mass spectrometer, and the Xevo TQ-S micro, a compact benchtop tandem quadrupole mass spectrometer.

The Xevo G2-XS mass spectrometer offers good analytical sensitivity and selectivity, providing laboratories with a dependable option for performing qualitative and quantitative experiments for both known and unknown analytes. The product combines the XS Collision Cell with the technologies of Tof-MRM, StepWave and QuanTof to deliver robust sensitivity and selectivity, resulting in the detection of low-level compounds. For targeted quantitative experiments, Tof-MRM mode is said to deliver a 10-fold improvement in signal-to-noise when compared to full scan mode.

The Xevo TQ-S micro is designed to acquire sensitive, robust and dependable data at accelerated rates for numerous analytes at varying concentrations. The small, high-performance tandem quadrupole mass spectrometer is a suitable choice for scientists working in food, environmental, pesticides, pharmaceutical bioanalysis and peptide screening.

Featuring Xtended Dynamic Range technology, the product offers six orders of magnitude of linear dynamic range - important for quantifying compounds in samples where the concentrations of individual analytes differ greatly. The wider the operational dynamic range, the easier it is to transfer methods between instruments of differing sensitivities.

The device’s Xcelerated Ion Transfer (XIT) electronics allow the instrument to acquire as many as 500 MRMs/s without significantly reducing peak intensities. This performance boost means that labs performing pesticide screening, drug and peptide analyses can monitor for a wide range of analytes.
