Identification of amino acids by using paper chromatography Aim To separation and identification of amino acids by using paper chromatography Introduction Chromatography is a techniques separation of mixtures It involves passing the sample, a mixture which contains the analyte, in the "mobile phase", often in a stream of solvent, through the "stationary phase." The stationary phase retards the passage of the components of the sample. When components pass through the system at different rates they become separated in time, like runners in a mass-start foot race. Each component has a characteristic time of passage through the system, called a "retention time." Chromatographic separation is achieved when the retention time of the analyte differs from that of other components mixtures in the sample. There are many types chromatography but there are four main types which are Liquid Chromatography Liquid Chromatography this is used in the world to test water samples to look for pollution in...
