Gas Chromatography-Mass Spectroscopy
cires1.colorado.eduGas Chromatography In general, chromatography is used to separate mixtures of chemicals into individual components. Once isolated, the components can be evaluated individually. In all chromatography, separation occurs when the sample mixture is introduced (injected) into a mobile phase. In liquid chromatography (LC), the mobile phase is a solvent.
Paper Chromatography - MIT SWE
swe.mit.eduPaper Chromatography is divided into two phases: S t a t i o n a ry P h a se and M o b i l e P h a se . Stationary Phase describes the paper before the solvents start to move up and Mobile Phase is when the solvents travels up the chromatography paper while carrying the solute (e.g. pigments). Objective:
Supercritical Fluid Chromatography
cao.chem.ufl.edu3. Supercritical fluid chromatography (SFC) a. SFC isa chromatographic technique in which the mobile phase is a supercritical fluid. b. The use of a supercritical fluid mobile phase in chromatography was first proposed in 1958 by J. Lovelock. The first actual report use of this in a chromatographic system was in 1962 by Klesper et al, who used it
EXPERIMENT 1: Thin-Layer Chromatography and Column ...
instruct.uwo.caChromatography is a common and extremely useful method used to separate and analyze complex mixtures. Using this technique the course of a reaction can be followed, and the products separated and isolated. In this method, the components within the mixture are distributed between two phases: a stationary phase and a mobile phase (which moves through
Paper Chromatography of Pigments in a Spinach Leaf
weissman.baruch.cuny.eduthe simplest of chromatography techniques called paper chromatography. Chromatography is an analytical method permitting the separation of a mixture into its molecular components. In this technique, a concentrated spot of the pigment mixture is deposited at one end of a paper strip. The paper strip is called the stationary phase.
Introduction to Liquid Chromatography
www.chem.tamu.eduWhat is Chromatography? Separation of a mixture into individual components. The separation uses a Column (stationary phase) and Solvent (mobile phase). The components are separated from each other based on differences in affinity for the mobile or stationary phase. The goal of the separation is to have the best
Thin Layer Chromatography (TLC) - Boston College
www.bc.eduPaper chromatography, which will be used to separate amino acids, is a form of partition chromatography (see LTOC page 253). Water, a component of the developing solvent, forms hydrogen bonds with the fibers of the paper and serves as the stationary phase. The organic liquids that are also present in the developing solvent serve as the mobile ...

How it works In all chromatography there is a mobile phase and a stationary phase. The stationary phase is the phase that doesn't move and the mobile phase is the phase that does move.
