What is HPLC? All about this chromatography technique!

In very small amounts the sample mixture to be separated and tested is sent into a stream of mobile phase percolating via a column There are different types of columns available with sorbents of varying particle sizes and surfaces The mixture moves through the column at varying velocities and interacts with the sorbent also known as the stationary phase

Chromatography

Chromatography technique for separating the components or solutes of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream called the mobile phase and a contiguous stationary phase The mobile phase may be either a liquid or a gas while the

Chromatography

Chromatography has a long and rich history as a separation technique The word "chromatography" was first used by Tswett in 1906 it is derived from the Greek words chroma (color) and graphien (to write) [1] Early applications of chromatography included noninstrumental techniques such as column and paper chromatography

Separation and purification

Chromatography Chromatography as noted above is a separation process involving two phases one stationary and the other mobile Typically the stationary phase is a porous solid (e g glass silica or alumina) that is packed into a glass or metal tube or that constitutes the walls of an open-tube capillary The mobile phase flows through the packed bed or column

The Basics of Running a Chromatography Column

Column chromatography is a common technique used to separate individual compounds from a mixture You can use column chromatography on both a small or large scale to isolate and purify material for use on a later experiment If you are new to column chromatography or just want a refresher then read on for a quick description of the basic process

CHROMATOGRAPHY MAIN CONCEPTS AND

INTRODUCTION Broadly chromatography refers to a number of separation techniques where molecules are distributed between two phases: a stationary phase often a chromatography resin and a mobile phase or eluent which in the case of protein separation is a solvent such as water or chloroform For commercial purifications chromatography is always carried out as column Chromatography

Column Chromatography Medical Definition

Medical definition of column chromatography: chromatography in which the substances to be separated are introduced onto the top of a column packed with an adsorbent (as silica gel or alumina) pass through the column at different rates that depend on the affinity of each substance for the adsorbent and for the solvent or solvent mixture and are usually collected in solution as they pass from
