Waters Xevo TQ Absolute tandem quadrupole mass spectrometer

Waters has introduced the Xevo TQ Absolute benchtop tandem mass spectrometer, designed to help pharmaceutical, food and beverage, and environmental analytical laboratories meet regulations requiring trace-level quantitative mass spectrometry analyses for a broad set of applications. It is suitable for laboratories looking for quantitative sensitivity, reproducibility, efficiency and sustainability.

Up to 15x more sensitive for quantifying negatively ionising compounds than its predecessor, the unit is 45% smaller and uses up to 50% less electricity and gas supply than other high-performance tandem quadrupole mass spectrometers available on the market, Waters claims. It offers high levels of analytical firepower in a small footprint, reaches low limits of quantitation and aids laboratory managers to optimise their equipment utilisation and analytical output.

The mass spectrometer incorporates thoughtful design features that enable consistent and reproducible analyses, allowing labs to maintain performance and uptime for long periods in between routine cleaning and service intervals. This is achieved with guidance on optimal probe positioning for both sensitivity and robustness and a source shield that helps minimise source contamination by the sample matrix or mobile phase salts.

The product is optimised for use with the waters_connect software platform and compatible with Waters MassLynx mass spectrometry software. For optimal performance, it can be paired with Waters’ ACQUITY Premier UPLC System with MaxPeak HPS technology which eliminates non-specific adsorption of compounds containing phosphate and/or carboxylate groups and improves their recovery. Together, this integrated LC-MS/MS system is designed to drive the limits of quantitation to low levels for many applications.
