Abstract

There have been a number of significant developments in the high-performance
chelation ion chromatography (HPCIC) of trace metals in recent years. This review
focuses on these developments, while giving important information on the fundamental
parameters controlling the chelation sorption mechanism, including type
of chelating group, stability constants, kinetics, and column temperature. The discussion
pays particular attention to the types and properties of efficient chelating
stationary phases which have been fabricated for certain groups of metals. The
review also describes a number of major improvements in postcolumn reaction
detection including the use of the latest reagents and noise reduction strategies to
improve sensitivity and reduce LOD. In the final section, an indication of the applicability
of HPCIC to a range of complex sample types is given with some key examples
and chromatograms using the latest high-efficiency chelating phases.
