Unformatted text preview: F, Y, W absorb UV (above 250 nm); also weak fluorescence, W has phosphorescence NMR: can characterize AA; at increased magnetic fields, can be used to find 3D structure Separation and Analysis o Ion exchange chrom.: sep. based on charge (cation exchange binds cations); can remove AA by changing pH or increasing concentration of counter ion o GC: sep. based on partition eq. o HPLC: sep by forcing liquid mobile phase through column at high pressure o reverse chrom.: derivatized AA bound to stationary phase and eluted w/ increasing concentrations of a polar substance...
