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.

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.

ChromatographyChromatography is a powerful technique used to separate and analyze components of mixtures based on their chemical properties. It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results.

The most well-known example of a biotherapeutic product, and the first to be approved for therapeutic use, was recombinant human insulin.LC-MSLiquid Chromatography-Mass Spectrometry (LCMS) is a powerful analytical technique that combines the separation power of liquid chromatography with the detection capabilities of mass spectrometry. It is widely used for qualitative and quantitative analysis of complex mixtures in pharmaceuticals, proteomics, and environmental studies.
