The only differences are that it uses a moving gas phase and a stationary liquid phase, and that the temperature of the gas system can be controlled. In a gas chromatograph the sample is shot in with a syringe and is immediately vaporized in a heated injection chamber. It is then introduced to a moving stream of gas called the carrier gas which sweeps the vaporized sample into a column filled with particles filled with liquid adsorbent. This column is usually filled with liquid that has a low vapor pressure and high boiling and is called the stationary phase.
This phase is also usually coated onto a support material very evenly and packed into a tubing apparatus as evenly as possible and placed in the temperature controlled oven. When organic solutions are passed through the tubing van deer Walls forces attract the monopole molecules especially if they have large molecular weights. Polar molecules can be attracted in many ways. Interactions include salt formation, coordination, hydrogen bonding, and even dipole-dipole. Through these interactions the molecules in the vaporized sample will separate accordingly.
Finally at the end here the gases come out is a detector which generates a signal that is recorded on a strip chart recorder. Elimination reactions are reactions that split a single reactant into two products. Elimination reactions can then be categorized as either an El (first order) or E (second order) reaction. In an El mechanism, a monomolecular elimination of water will result in an alkyl action. In an E mechanism, a bimolecular reaction occurs in which water acts as a base, abstracting a a-hydrogen. The direction of the elimination reaction forming alleles is typically governed by Gazette’s ole.
