Americas: Thermo Fisher Scientific introduces HRAM spectral library for food analysis

Thermo Fisher Scientific announces its high resolution accurate mass (HRAM) spectral library for laboratories analyzing environmental, clinical research/toxicological and food samples.

The company made the announcement at the 62nd ASMS Conference on Mass Spectrometry and Allied Topics, in Baltimore, USA from June 15 to 19, 2014.

“This is a library with full, high-resolution spectra for every compound it contains,” said Jennifer Massi, program manager, environmental and food safety.

“In fact, we ran multiple tandem mass spectrometry (MS/MS) spectra for each compound, and each was analyzed at multiple collision energies. This is designed to enhance method flexibility and confidence in results.”

The library was generated using the Thermo Scientific Q Exactive liquid chromatography-mass spectrometry (LC-MS) system at 140,000 resolution to minimize false positives and negatives as well as matrix interference.

Spectra are searchable using Thermo Scientific TraceFinder software.

The library contains compounds for environmental and food safety analysis that include: pesticides, mycotoxins, veterinary drugs, perfluorinated chemicals or PFCs and other environmental contaminants.

For clinical/toxicological research, it contains spectra for therapeutic and prescription drugs, illegal drugs and toxins.

The library is designed to help users save time in method development by using defined retention times and by searching the five most intense ions.

The library mitigates the need to purchase standards to set up new libraries.

Method development flexibility is enhanced because spectra are generated at multiple collision energies per compound.
