Summary

Results from the NMR determination of phosphorus by destructive and non destructive methods are given. A microdetermination of boron is described, including the choice of relaxing agents and reference compounds. Reproducibility studies on reference capillaries and some preliminary results indicate an accuracy of ±1% for compounds with high boron content. Once set up, the method requires little preparation and only a short time on the instrument.

Zusammenfassung

Die Ergebnisse einer Serie von Phosphorbestimmungen an aufgeschlossenen und intakten Verbindungen wurden mitgeteilt. Eine Mikromethode für Bor wurde beschrieben, einschließlich der Wahl der Relax-Agentien und des Massenstandards. Die Reproduzierbarkeit der Standardisierung und erste Resultate zeigen eine Genauigkeit von ±1 % für Verbindungen mit hohem Borgehalt. Im Betrieb erfordert die Methode wenig Vorbereitung und nur kurze Zeit am Instrument.
