Chromatography explained

Affinity chromatography

Affinity chromatography Affinity chromatography is a chromatographic method of separating biochemical mixtures, based on a highly specific biologic interaction such as that between antigen and antibody , enzyme and substrate , or receptor and ligand . Affinity chromatography combines the size ...

Chiral column chromatography

Chiral column chromatography Chiral column chromatography is a variant of column chromatography , where the stationary phase is chiral instead of achiral. The enantiomer s of the same compound then differ in affinity to the stationary phase, thus they exit the column at different times. The chir ...

Chromatographic Separation Methods in Simple Terms

Separating mixtures of substances to analyze them qualitatively and quantitatively – these are the chromatographic methods you should know about ...

Chromatography

Chromatography Chromatography (from Greek χρώμα:chroma, colour and γραφειν:"grafein" to write) is the collective term for a family of laboratory techniques for the separation of mixtures . It involves passing a mixture dissolved in a "mobile phase" through a stationary phase, which separates ...

Column chromatography

Column chromatography Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds. It is often used for preparative applications on scales from micrograms up to kilograms. The classical preparative chromatography column is a glass tube ...

Fast protein liquid chromatography

Fast protein liquid chromatography Fast Protein Liquid Chromatography, usually referred to as FPLC, is a form of column chromatography used to separate or purify proteins from complex mixtures by using Ion Chromatography . It is very commonly used in biochemistry and enzymology . Columns used w ...

Gas-liquid chromatography

Gas-liquid chromatography Gas-liquid chromatography (GLC), or simply gas chromatography (GC), is a type of chromatography in which the mobile phase is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen , and the stationary phase is a microscopic layer of li ...

Gel Permeation Chromatography

Gel Permeation Chromatography Gel permeation chromatography (GPC) is a separation technique based on hydrodynamic volume (size in solution). Molecules are separated from one another based on differences in molecular size. This technique is often used for polymer molecular weight determination. GP ...

High performance liquid chromatography

High performance liquid chromatography High-performance liquid chromatography (HPLC) is a form of column chromatography used frequently in biochemistry and analytical chemistry . It is also sometimes referred to as high-pressure liquid chromatography. HPLC is used to separate components of a mixt ...

Hydrophilic interaction liquid chromatography

Hydrophilic interaction liquid chromatography HILIC (HydrophILic Interaction Chromatography or Hydrophilic Interaction LIquid Chromatography) is a version of normal phase liquid chromatography a name suggested by Dr. Andrew Alpert in his 1990 paper on the subject (J. Chromatogr. 499 (1990) 177) whe ...

Mixed-mode chromatography

Mixed-mode chromatography Mixed-mode chromatography is a type of chromatography . In liquid chromatography , several modes of separation are commonly applied to resolve a mixture of different molecules. Ion-exchange chromatography , normal phase chromatography , reversed phase chromatography , size ...

Size exclusion chromatography

Size exclusion chromatography Size exclusion chromatography (SEC) is a chromatographic method in which particles are separated based on their size, or in more technical terms, their hydrodynamic volume . It is usually applied to large molecule s or macromolecular complexes such as proteins and ind ...

Supercritical fluid chromatography

Supercritical fluid chromatography Supercritical Fluid Chromatography (SFC) is a robust and easy-to-use form of normal phase chromatography ideally suited to the analysis and purification of low to moderate molecular weight, thermally labile molecules. It is especially suited to the separation of ...

Thin layer chromatography

Thin layer chromatography Thin layer chromatography (TLC) is a chromatography technique used to separate chemical compounds . It involves a stationary phase consisting of a thin layer of adsorbent material, usually silica gel , aluminium oxide , or cellulose immobilised onto a flat, inert carrie ...
