- ... A novel methodology for the determination of ornithine, putrescine, cadaverine, spermidine and gamma-amino butyric acid in urine samples has been developed. The method uses in situ aqueous derivatization followed by automated microextraction by packed sorbent coupled to a gas chromatography–mass spectrometry system equipped with a programmed temperature vaporizer. This instrumental configuration m ...
