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. Find the best UHPLC and HPLC equipment in our peer reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. 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.EnzymesEnzymes are macromolecular biological catalysts used across life science, pharmaceutical and clinical research. Various enzymes can be purchased for research applications including ligases, high fidelity polymerases, nuclease, protease, restriction enzymes, tissue dissociation enzymes and enzyme inhibitors. Find the best enzymes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.MetabolitesMetabolites are the intermediate and end products of metabolism. Analyzing metabolites offers insight into cellular processes and disease mechanisms and is critical in fields like pharmacology, toxicology, and diagnostics. Explore our peer-reviewed product directory to find the best tools for metabolite analysis, compare products, check reviews, and get pricing directly from manufacturers.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.PharmaceuticalsPharmaceuticals are medicinal drugs used in healthcare to diagnose, prevent, cure and treat illnesses. Pharmaceuticals that are excreted after use appear in wastewater and can have detrimental effects on the environment.UrineThe analysis of urine is important in medicinal, anti-doping, forensic and life sciences applications. The ability to evaluate what someone has ingested through their urine enables fast detection and diagnosis of certain illnesses.
