Separation of molecules is performed using Size Exclusion Chromatography (SEC), which separates molecules based on size as they pass through a porous resin. Widely used for both preparative and ...

Reviewed by Dr. Catherine Shaffer, Ph.D. Chromatography (from the Greek words chroma, "color," and graphein, "to write") is a method for the separation of a mixture. In simple terms, the process ...

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 ...

Fast protein liquid chromatography (FPLC) is, as the term implies, an effective (fast) liquid chromatography technique for the separation of protein molecules. The term also implies that the mobile ...

Explore different protein purification methods like ion exchange, affinity chromatography, and size exclusion, and understand ...

Analysts interested in quantifying volatile organic compounds like disinfection byproducts in liquid samples should consider using the gas chromatography system. There are two gas chromatography (GC) ...

Analysts interested in quantifying volatile organic compounds or pesticides in liquid samples should consider using the gas chromatography - mass spectroscopy (GC-MS) system. The gas chromatography ...

Inverse gas chromatography, also known as IGC, is a gas phase technique that was developed over forty years ago to inspect the bulk and surface properties of fibrous and particulate materials. Until ...

Chromatography refuses to be overwhelmed by the processing demands and cost pressures associated with next-generation medicines. Instead, chromatography is strengthening its commitment to innovation.

Manual sample prep consumes 60% of time spent during analysis and contributes to 30% of errors. Automated sample prep ...
