New Glass Capillary Gas-Chromatographic Methods for Metabolites in Urine and Serum

  • Werner Dosch


The analytical system suggested in this paper is a further development of pre-chromatographic methods and of column switching techniques described in previous papers1,2,3.In order to use modern gas-chromatographic techniques for the determination of metabolites in urine and serum quick and reliable pre-chromatographic methods for extraction, concentration and derivatization must be developed which give final (dosage) volumes of 5 to 10 μl with starting sample volumes of 0.1 ml of urine or 5 ml of serum as described by Dünges4.
