High Performance Liquid Chromatography - Manufacturers, Traders & Suppliers HPLC (high performance liquid chromatography) is a chemical-analytical process for separating liquid, non-volatile, complex mixtures of substances unknown in the composition and for evaluating a qualitative (what is contained?) and quantitative (how much is contained?)
HPLC is a technique that uses high pressure to push samples through a chromatography column to separate out the compounds that make up the sample. The process of separating different compounds depends on the type of chromatography column used. Several different types of columns are described below. Once the molecules make it through the column

HPLC offers a higher separation performance (higher purity and higher yield), ease of scale up, and reduces the number of fractions collected, which need to be analyzed individually. Flash chromatography is a separation technique like HPLC that is operated at low/medium pressure. The stationary phase used in flash chromatography is composed of
Bottle Caps Bottle caps provide an air-tight seal that ensures that a bottle’s contents are leak- and spill-proof, resistant to temperature and that the bottle can be moved. The most ubiquitous style is the threaded screw cap. Caps are available in different sizes and colors and can be specialized for the type of container they sit upon.
