Liquid scintillators used in low counting rate experiments – like solar neutrino experiments – usually have to fulfil high requirements concerning their radiopurity. In that context silica gel chromatography is a promising purification method to extract traces of polar impurities out of liquid scintillators. The paper presents a purification model describing two different purification modes and compares it to laboratory experiments performed during the last years. Some of them – large scale purification tests – have been realised at the CTF, prototype of the solar neutrino experiment Borexino.
