Summary

A computer has been used for rapid and exact identification of mass spectra for the barbiturates presently on sale in Sweden. The compounds were isolated from blood, or liver from intoxicated persons in suicide cases and a small part of the chloroform extracts were analyzed on a gas chromatograph-mass spectrometer instrument. The mass spectra were recorded on a digital tape off line system and the tape was evaluated and processed by the computer. The amount of tissue or blood was in the magnitude of less than 50 mg in these cases.

Zusammenfassung

Es wurde ein Computer für eine schnelle und exakte Identifizierung der Massenspektren zum Nachweis von Barbituraten, die zur Zeit im Verkauf in Schweden angeboten werden, angewandt. Aus Blut- oder Leberproben der Personen, die Selbstmorde durch Vergiftung begangen haben, wurden Substanzen isoliert und eine geringe Menge der Chloroformextrakte mit Hilfe der Gaschromatografie-Massenspektrometrie(GC-MS)-Apparatur analysiert. Die Massenspektren wurden auf einem Digitalband aufgezeichnet und danach durch den Computer bewertet und wiedergegeben. Das Gewicht der Gewebe und des Blutes in den untersuchten Fällen lag unter 50 mg.
