Abstract

In the meeting on PCB analyses organized in Ulm, Donau, West Germany, 11-13 April 1984, where the second ringtest 2/1983 (Report 84.27 d.d. 1984- 03- 26) was discussed, it was decided to organize a next ringtest. In this ringtest identification and quantification of some individual chlorobiphenyls should he carried out in the extracts of eel-fat samples (cleaned-up by saponification) using splitless injection (part 1) and/or on-column injection after optimization (part 2). For the optimization of the on-column injection prof. D.L. Massart of the University of Brussels, Belgium had offered his cooperation to find the optimum settings by using a computer program. During a discussion meeting with prof. D.L. Massart on dd. 1984- 05-24 in Brussels, it was decided to use a factorial design for optimization. As variables were chosen the ''temperature'' of the injector, the starting temperature of the column and the temperature programming rate. As criteria were chosen peak hight, peak width, peak area, tailing and resolution. In this report the results of the on-column injection are given and the data obtained with direct injection.
