Abstract
Development of new chromatographic method is often time-consuming and may be shortened by mathematical modeling. Unfortunately, many of the models are limited for predefined elution programs only. The integral model uses iso-to-grad approach to transfer information from isocratic to gradient elution without such limitations, which was successfully tested for IC and HPLC using single-species eluents. Here its applicability was tested on systems using more complex eluents. An HPLC analysis of emerging contaminants using methanol/acetonitrile/water eluent was performed. Four different integral models were developed and validated. The models showed good predictive ability.
