Liquid chromatography. In liquid chromatography, a system consists of a column filled with stationary (or solid) phase, mobile phase(s), detection instrument(s) and pump(s) to move a mixture through a ...

Liquid chromatography uses a liquid mobile phase, with the stationary phase being on a planar surface or packed into a column. High-performance chromatography (HPLC) and ultra-high-performance liquid ...

What is gas chromatography and liquid chromatography? Gas chromatography is a chromatographic method that uses gas as a mobile phase.The sample flows through the gas system and is gasified before ...

Columns used for GC are long and thin, while HPLC columns are shorter and wider. HPLC also requires expensive solvents and a pressure pump to push the mobile phase through the column. On the other ...

It pioneered ultra performance liquid chromatography (UPLC) in 2004 with the launch of the Acquity UPLC Column. With up to 9x faster separations and 80% reduction in solvent usage compared to HPLC, it ...

A UHPLC column is a piece of apparatus used in ultra-high performance liquid chromatography that allows greater separation efficiency, improved resolution, and shorter analysis time compared with ...

Monolithic columns represent a significant advancement in liquid chromatography, utilising a continuous, porous structure to facilitate rapid and efficient separations. Unlike traditional packed ...

Flash column chromatography is a method of chemical separation that is used to purify chemical mixtures. It is also known as flash purification, due to its function as a purification method. It is ...

The first micro-fabricated column for gas chromatography was reported in 1979; however technological problems and limited performance have so far hindered its widespread commercialization and use. On ...
