Sample clean-up via GPC (gel permeation chromatography) is used for all samples in the analysis of residues and contaminants and is therefore universally applicable. he FREESTYLE GPC is a fully automated chromatographic sample preparation system, that is used for example for clean-up of food, feed and environmental samples. It complies in all areas with the requirements of general methods, e.g. L 00.00-34, EPA 3640A.


Particularly user-friendly is the combination of the FREESTYLE GPC with the EVAporation module. The chosen fraction is collected online in the vacuum chamber and after concentration transferred into one or several vials (e.g. GC vials). The result is a sample, which can be directly introduced into the analyser.
