Hexavalent Chromium Determination by Two-Dimensional Capillary Ion Chromatography Using a Monolith Concentrator Column

[steve-day]

This work will show the results of adapting a 2D system for use in hexavalent chromium (chromate or CrO4 2- ion) determination of drinking water samples using suppressed conductivity detection. Minimum detection limits (MDLs) better than existing methods will be demonstrated.
