Waters has unveiled new mass spectrometry technologies developed to serve the multi-faceted analytical requirements of food testing. The new products include a gas chromatography-mass spectrometry/mass spectrometry (GC-MS/MS) system for food safety analysis and a direct-analysis mass spectrometry system for rapid molecular fingerprinting of food commodities, ingredients and processed products.

The mass spectrometry products are on display at the 66th Conference on Mass Spectrometry and Allied Topics (ASMS), which is currently underway and will conclude on June 7, 2018.

At ASMS, Waters will preview its new Xevo TQ-GC mass spectrometer, GC-MS/MS system for food safety and quality laboratories. The system, which will be officially launched later this year, allows laboratories to consistently meet and exceed limits of detection when quantifying pesticides residues and other contaminants in food using GC-MS/MS methods set forth by worldwide regulatory agencies/authorities.

“Hundreds of pesticides are in use throughout the world, and with other emerging contaminants regularly coming to the attention of regulatory authorities, laboratories need to be able to accurately detect and quantify pesticides in a variety of food types and GC-MS/MS, along with liquid chromatography-mass spectrometry (LC-MS), is the preferred technique of choice for the majority of them,” stated the company.

The product of a collaboration between Waters and IonSense, Inc has led to the development of the Direct Analysis in Real Time (DART) QDa with LiveID System.

This is a direct analysis system for rapid molecular fingerprinting of food commodities, ingredients and processed products. It allows scientists to assess if the testing is authentic.

Featuring the LiveID software platform, the instrument performs real-time sample recognition and verifies sample authenticity or adulteration in seconds.

DART is a direct and rapid analysis technique for various sample types with minimal sample preparation and no requirement for a chromatographic separation.

The Waters LiveID software trains and validates multivariate statistical models using the chemical profile obtained from the DART QDa analysis.

The LiveID models can be used to identify unknown samples, generating easy-to-interpret results in near real time and a simple yes/no answer in seconds.
