Multi-detection size exclusion chromatography (SEC) is a combination of column chromatography and light scattering, ultra violet (UV), viscometer and refractive index (RI) detectors, making it a ...

Chromatography is a process by which compounds within a mixture are separated. Compounds are be separated by properties such as size, and how the compounds interact with the mobile and stationary ...

Chromatography has long been the workhorse of high-resolution bioseparation. It is the most commonly used technique for preparative work, and is second only to electrophoresis in analysis. Most ...

A pencil line is drawn, and spots of ink or plant dye are placed on it. There is a container of solvent, such as water or ethanol. A pure substance will only produce one spot on the chromatogram ...

The wide range of chromatographic techniques share one common aim: to separate a material into its components. A material, your sample, is dissolved in a solvent, called the mobile phase. This mixture ...

Alas, where there once was togetherness is now a separation. In chromatography, explains Pirkle, what separates disparate entities in a chemical mixture, such as a cell extract of thousands of ...

Chromatography is a process for separating components of a mixture for analysis. This is a component of our small molecule analysis testing and plays a critical part in identifying and quantifying ...

One-dimensional gas chromatographic (1D-GC) analyses of complex environmental, petrochemical, or biological samples often result in a chromatogram with a large portion of unresolved components. Mass ...
