High resolution mass spectrometry is an emerging practice in laboratory analysis that determines a compound's identification to a higher degree of accuracy and precision using the compound's fragmentation spectrum. The collection of those spectra for an array of compounds can be organized into a shareable high-resolution mass spectral library.
Overview
High-Resolution Mass Spectral Libraries for Drug and Toxin Analysis.
Mass spectrometry is used by laboratories to confirm the presence of chemical compounds in clinical, toxicological, and environmental samples. Laboratories also use mass spectrometry to analyze the structure of a compound by breaking down the compound into its components and measuring their mass and intensity. This is called a fragmentation mass spectrum and the data is shared in a mass spectral library. The library can provide reference data to increase confidence in compound identification when commercial standard reference material is unavailable.
The high-resolution mass spectral libraries for opioid analysis available below include data that enable identification of all the 200+ opioids and opioid-related compounds also covered by the TOM Kits® product line.
Multiple library formats are provided for use on Agilent, Sciex, or Thermo mass spectrometry platforms. The NIST library format, created from data collected on an Agilent QTOF for the FAS Kit and on a Thermo Exploris 480 for the EDP Kit, is also available for use on these and other instrument platforms.
