•Ion Chromatography
Detection
•Basic detector is
conductivity, but others
are used such as UV-vis
& atomic spectrometry (AA, AE) for metals
•Measure conductivity
change in effluent when analyte passes through
•Problem – use high [H+]
to elute small [Mx+] which makes it difficult to
detect [Mx+] conductivity on high background of [H+]
•This problem hindered
development of IC until the innovations made at Dow in 70’s
