✦ Synopsis

An automated version of an exlstmg batch method for the determmatlon of blttemess m wgm olive 011 was developed The automatic method 1s based on flow-mjection analysis @IA) prmclples and 1s Implemented by couphng an FIA mamfold to a sohd-bqmd retention unit m which the sample matm IS retamed on a C,,-bonded slhca-packed mmlc&unn, the analytes being momtored by UV spectrophotometry and the retamed matrur bemg eluted m the opposite duectlon to detection, so it never reaches the detector The automatic method clearly surpasses its manual counterpart in terms of solvent savmgs, analysis time (5 vs 50 mm) and labour requirements (none of the tedious prehmmary steps of the manual method need be Implemented
