Toxtyper™ – a Comprehensive LC-MS/MS Screening Solution for Clinical and Forensic Toxicology
4 Jan 2013A major task for clinical and routine toxicology screening is the reliable, fast and comprehensive identification of drugs and drugs of abuse (DOA). LC-MS/MS is an emerging technology that is more specific than immunoassays, provides more information than LC-UV/DAD detection, and covers a broader range of compounds than GC-MS. This application note describes a robust and automated screening solution based on the latest LC-MS/MS ion trap technology that promises to provide a combination of the highest performance LC-MS/MS and easy-to-use screening with the greatest transferability of results from lab to lab.

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 ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.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.Toxicology ScreeningForensic 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.Drugs of AbuseA drug of abuse is a drug that has been taken for non-medical purposes. Such drugs can have mind-altering effects, with some causing dependence and addiction.Drug TestingIt is essential to test the efficacy and toxicity of drugs at every stage of their development to ensure that a pharmaceutical product is fit for purpose and safe for use before reaching the stage of mass production and distribution.Ion TrapScreeningUsing robotics, data processing and control software, liquid handling devices and sensitive detectors, screening allows a researcher to quickly conduct millions of chemical, genetic or pharmacological tests.Compound Identification
