Directory Listings Chromatography Introduction to this part of chemistry which is a broad range of physical methods used to separate and or to analyze complex mixtures. The components to be separated are distributed between two phases: a stationary phase bed and a mobile phase which percolates through the stationary bed. http://www.rpi.edu/dept/chem-eng/Biotech-Environ/CHROMO/chromintro.html - profile Gas Chromatography Details about this chemistry topic which involves a sample being vapourised and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase. The column itself contains a liquid stationary phase which is adsorbed onto the surface of an inert solid. http://www.shu.ac.uk/schools/sci/chem/tutorials/chrom/gaschrm.htm - profile |
