This presentation will focus on recent developments from our laboratory in the area of ion chromatography (IC).Three topics will be covered in an effort to show the broad range of current developments in IC.The first area is computer-assisted method development in IC.Because of the availability of on-line eluent generation in IC, complex elution profiles comprising up to 5 sequential isocratic and linear gradient steps are frequently used in the separation of complex mixtures.Computer-assisted method development greatly reduces the time required for selecting the best complex elution profile.Software based on predicting retention using analyte velocities will be describes and it will be demonstrated that this software can accurately predict the retention of ionic analytes (both anions and cations) under complex elution profile conditions.The use of this software will be illustrated for both inorganic and organic analytes.The second area relates to the recent introduction of capillary IC and the consequent need to translate exiting IC separation methods on conventional scale columns to the new capillary format.New software has been developed which enables the rapid transport of separation conditions between columns of different dimensions.This "porting" software will be described and its use for routine transfer of IC methods to different column dimensions will be described.
