When the components in the mixture of solutions are moved forward in the mobile phase by the material moving the sample, these components pass through the stationary phase. The difference in size and ...

Chromatography remains a cornerstone in the purification of proteins, offering a suite of techniques that separate components based on differential interactions with a mobile phase and a stationary ...

Chromatography testing and mass spectrometry are two analytical techniques widely used in scientific research, pharmaceuticals, food safety, environmental analysis, and forensic investigations. These ...

Chiral separation techniques in liquid chromatography (LC) have evolved considerably over recent decades, driven by the need to distinguish between enantiomers that, although chemically identical, ...

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 ...

In this Technique Blast – a new series that will provide short, informative discussions about a specific technique – Digital Editor, Tristan Free, speaks with Joseph Pesek (San José State University, ...

In this interview conducted at Pittcon 2023 in Philadelphia, Pennsylvania, we spoke to this year's recipient of The Chromatography Forum of the Delaware Valley Dal Nogare Award, Luis Colón. Please ...

What is gas chromatography and how does it work? Separation of analytes by GC is based on the physical and chemical properties of the compounds within the sample. Samples may be solid, liquid or gas ...

Due to their simultaneous expression, enveloped virus-like particles (VLPs) and extracellular vesicles (EVs) are difficult to distinguish and separate for analytical purposes. In addition to their ...

Whether we know it or not, we rely on a host of analytical techniques in many aspects of our lives, from developing medications to keeping our food safe to enforcing the law. Many of the compounds ...
