Offline Postcolumn Derivatization

This is perhaps the most unwieldy derivatization approach of all (Table 2). It involves separating the analyte of interest from the LC eluent prior to detection, performing a solution or solid-phase derivatiz-ation away from the instrumentation, manually or automatically, and then detecting the final derivatized solution. Automation is difficult, reproducibility is less than ideal, and even accuracy and precision falter, at times, because of a lack of total automatability. Thus, this mode receives the least emphasis in the literature and the lowest recommendation of application.
