Microchimica Acta Aims and scope Submit manuscript

Summary

This report records procedures for the determination of microgram quantities of the six platinum metals. The methods will have application to the analysis of small crystals of the minerals of the platinum group, particularly iridosmines and to the analysis of the “insoluble” portion of assay buttons and beads.

The scheme incorporates several new methods of separation and makes use of a variety of the most suitable methods of determination. Variations in these methods have been introduced in order to increase their efficiency and to invite their use.

Zusammenfassung

Ein Arbeitsgang für die Trennung und kalorimetrische Bestimmung von Mikrogramm-Mengen der sechs Platinmetalle wird beschrieben. Er wurde für die Analyse kleiner Kristalle von Platinerzen, besonders von Osmiridium, und „unlöslicher“ Rückstände, die bei der Untersuchung von Kupellationsperlen auftreten, ausgearbeitet und enthält mehrere neue Trennungsverfahren, an die sich die geeignetsten Bestimmungsverfahren anschließen. Die hierfür ausgearbeiteten Verbesserungsvorschläge sollen zu vermehrter Anwendung anregen.

Résumé

Description de techniques de détermination des 6 métaux de la mine du platine en quantité de l'ordre de grandeur du microgramme. Ces méthodes sont applicables à l'analyse de petits cristaux de minéraux du groupe du platine, en particulier à celle des osmiures d'iridium et à celle de la fraction «insoluble» des boutons et perles d'essai.

Le schéma analytique comporte plusieurs méthodes nouvelles de séparation et met en oeuvre un certain nombre de méthodes de détermination choisies parmi les plus commodes. Les auteurs leur ont apporté des modifications afin d'accroître leur rendement.
