[Contamination by use of Extrelut columns (author's transl)].
Extrelut columns commonly used to isolate metabolites from biological fluids often contain fatty acids, phthalates, alcohols and especially resin acids which occassionally cause great analytical problems. Therefore purification before use of Extrelut columns is strongly recommended.
