Zusammenfassung
Die Analyse von biologischem Material mit der Funken-Massenspektrometrie wird beschrieben. Erste Untersuchungen basieren auf der Analyse der NBS-Standardprobe „Orchard Leaves“ (NBS SRM-1571). Die Wichtigkeit einer geeigneten Probenvorbereitung wird betont. Die Vorteile der Naßaufschlußtechnik in einer Teflonbombe werden diskutiert und ihr Einsatz durch die gute Gesamtreproduzierbarkeit von etwa 20% gerechtfertigt.
Summary
Analysis of biological material by spark source mass spectrometry is reported. Preliminary studies mainly based upon the analysis of the NBS standard reference material SRM-1571 (“Orchard Leaves”) are described. Attention is drawn to the importance of a suitable sample preparation method. The advantages of a wet digestion technique in a Teflon bomb are discussed and its use is justified by the satisfactory overall analysis precision of about 20%.
