The options for conducting quantitative analysis are similar to those adopted in HPLC (1 ). The output format is similar to an HPLC chromatogram, i.e., a plot of UV absorbance vs time. Therefore, HPLC data handling and peak integration packages are generally applicable to CE. Main component assay may be performed using external and internal standardization or by standard addition. Impurity data can be calculated and reported as either % w/w or % area/area.
