Laboratories analyzing environmental, clinical research/toxicological, and food samples have a powerful new data tool expected to save time and money while identifying compounds with high levels of confidence.

Thermo Fisher Scientific announces its high resolution accurate mass (HRAM) spectral library at the 62nd ASMS Conference on Mass Spectrometry and Allied Topics, being held at the Baltimore Convention Center from June 15-19 in booth 127 and at the Holiday suite in the Hilton Baltimore Hotel.

“This is a true library with full, high-resolution spectra for every compound it contains,” said Jennifer Massi, program manager, environmental and food safety for Thermo Fisher Scientific. “In fact, we ran multiple 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 (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 customers save time in method development by using defined retention times, and by searching the five most intense ions. Customers can save money because the library reduces 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.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.Forensic ToxicologyForensic toxicology is used to determine cause of death, drug use and contaminations. Toxicological evaluations are commonly used in analytical chemistry, clinical, life sciences and forensics.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.
