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.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.Amino AcidsFood QualityFood quality refers to the attributes of food that influence its safety, nutrition, and taste. Monitoring and ensuring food quality are essential in production to meet health regulations and consumer expectations. Techniques like spectroscopy, chromatography, and microbial testing are used to assess food properties and detect contaminants.
