              Dionex DX-500 Ion Chromatogaph/HPLC (1995) 

        1.  Ion chromatography is used for measuring ions in aqueous systems

        2.  IC is a subset of HPLC, which is used largely for polar to nonpolar 
             organics in more nonpolar solvents.

        3.  Dionex (a spinoff from DOW) made the first useful IC (late 70's) when 
            they patented suppressor systems, which reduce the background
            conductance signal of the eluent.

        4.  Most IC systems use a conductance detector.
