Gas Chromatography-Mass Spectroscopy

Gas Chromatography-Mass Spectroscopy Introduction Gas Chromatography-Mass Spectroscopy (GC-MS) is one of the so-called hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals. Gas chromatography separates the components of a mixture and mass Spectroscopy characterizes each of the components individually. By combining the two techniques, an analytical chemist can both qualitatively and quantitatively evaluate a solution containing a number of chemicals.

Gas 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.

Gas Chromatography-Mass Spectroscopy

Mass Spectroscopy As the individual compounds elute from the GC column, they enter the electron ionization (mass spec) detector. There, they are bombarded with a stream of electrons causing them to break apart into fragments. These fragments can be large or small pieces of the original molecules.

Paper 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).

3. 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

Chromatography 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

the 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.

What 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

phase than the solutes that prefer the stationary phase. As the solutes move through the stationary phase they separate. This is called chromatographic development. 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.
