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.Infrared / IR SpectroscopyInfrared (IR) spectroscopy measures the interaction of infrared light with a sample, including transmission, reflectance & absorbance, facilitating the identification of analytes. Equipment used for quantitative analysis includes Fourier-transform infrared (FTIR) spectrometers, infrared cameras, FTIR gas analyzers, as well as attenuated total reflectance (ATR) accessories and pellet or film presses. Find the best IR spectroscopy products 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. Visit our product directory to receive quotes direct from the manufacturer. Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available. Find the best Raman spectroscopy products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis. Find the best GC-MS instruments and equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.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.Drinking Water AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Ultrapure WaterUltrapure water is the highest purity water and contains the lowest levels of organic and inorganic contaminants, particulates and microorganisms.PesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA. Environmental ForensicsPharmaceuticalsPharmaceuticals 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.Pure WaterPure water is processed to remove significant level of contaminants and is suitable for use in many laboratory applications.
