Chemistry - Chromatographic techniques

Chromatographic techniques

Chromatography can be used in both qualitative and quantitative analysis.
Sometimes referred to as separation science it is used to separate the
components of a mixture by selective removal from a moving fluid (gas or
liquid). In all forms of chromatography there are two distinct phases: a
stationary phase and a mobile phase

The moving fluid, referred to as the mobile phase, passes over the
stationary phase. The components of the mixture are separated according to
their relative attractions to the mobile and stationary phases.

The four main types of chromatography are:

* Paper chromatography,

* Thin-layer chromatography,

* Gas chromatography (GC) and

* High performance liquid chromatography (HPLC).
