that chiles were used as a food ingredient at least 8‚000 years ago - around 6200 BC. Traces of chiles dating from this time have been found in burial in Peru: they were obviously seen as important enough to be carried into them hereafter! Chile peppers are thought to have been domesticated at least five times by prehistoric peoples in different parts of South‚ Middle and North America‚ from Peru in the south to Mexico in the north and parts of Colorado and the Ancient Pueblo Peoples of New Mexico

Principles of Chromatography Substances present in a mixture are allowed to distribute themselves between two phases: the stationary phase (fixed) and the mobile phase. As the mobile phase flows over the stationary phase‚ components of the mixture experience many transfers

EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed

Chromatography is a process used to separate mixtures. The word chromatography is derived from the Greek words ‘khroma’ and ‘graphein’ meaning ‘color’ and ‘to write’ or to represent. Although there are a couple different types of chromatography‚ in each case a substance is placed onto or into a medium and a solvent is passed through the test substance. In chromatography science‚ the solvent is called the mobile phase or the carrier fluid and the medium is called the stationary phase. There are four

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis.

Paper Chromatography Chromatography comes from the Greek word khromatos (color) and graphein (to write); i.e. paper chromatography is literally color writing on paper. This method tests the purity of compounds and identifies substances. This analytical process‚ despite having been replaced by the success of thin layer chromatography‚ still stands as a valuable teaching tool‚ and is nevertheless very common. This method is very useful because not only is it a relatively quick process‚ but also
