Webb13 nov. 2024 · 12.5: High-Performance Liquid Chromatography. In high-performance liquid chromatography (HPLC) we inject the sample, which is in solution form, into a liquid mobile phase. The mobile phase carries the sample through a packed or capillary column that separates the sample’s components based on their ability to partition … WebbWhich HPLC and UHPLC autosampler is right for you? Innovative and carefully designed Thermo Scientific autosamplers and sampler extension module ensure reliable, precise and accurate injection for nanoliter to milliliter sample volumes. They support a wide range of formats and sample throughputs.

WebbIn general, a HPLC system contains the following modules: a solvent reservoir, a pump, an injection valve, a column, a detector unit and a data processing unit (Fig. 1). The solvent (eluent) is delivered by the pump at high pressure and constant speed through the system.

Webb6 sep. 2024 · HPLC injection is a technique to inject the sample without disturbing the flow rate and pressure of the HPLC system. The working pressure of an HPLC is … HPLC separations have theoretical parameters and equations to describe the separation of components into signal peaks when detected by instrumentation such as by a UV detector or a mass spectrometer. The parameters are largely derived from two sets of chromatographic theory: plate theory (as part of Partition chromatography), and the rate theory of chromatography / Van Deemter equation. Of course, they can be put in practice through analysis of HPLC chromatogr… WebbThe simplest way to inject your sample into the system.
