The 14th Australian Symposium on Analytical Chemistry. Adelaide, 5–9 July 1997

 The Analytical Division of the Royal Australian Chemical Institute (RACI) held its 14th biennial symposium on analytical chemistry (14AC) in Adelaide, South Australia on 5–9 July 1997 [1]. The theme, "A broader view of the world" was an explicit invitation from the organisers to analysts to "take time away from their laboratories and consider how their work affects the world . . . A major challenge to chemists is to redefine their role in industry, education and the community and face, head-on, the demands brought about by free trade, economic rationalism and the environment." Part of this challenge, as reflected in invited plenary and keynote speakers as well as the cut and thrust of debate on the conference floor, is to address the important role of chemical measurement and confidence in the domestic and international systems of measurement.     

Development of Analyses of Biological Steroids Using Chromatography——Special Reference to Vitamin D Compounds and Neurosteroids

Steroids comprise a large group of natural substances that must frequently be monitored in various biological materials. Due to the metabolic versatility of steroid molecules, extremely complex mixtures are often encountered, necessitating the use of a chromatographic procedure prior to measurement. In this article we present our work, that is, the development of analyses of biological steroids (especially vitamin D compounds and neurosteroids) using gas chromatography/mass spectrometry, high-performance liquid chromatography (including inclusion chromatography using cyclodextrin) and liquid chromatography/mass spectrometry.     

An EPMA Study on KNbO3 and NaNbO3 Single Crystals – Potential Reference Materials for Quantitative Microanalysis

Single crystals of KNbO₃ and NaNbO₃ were selected from the limited number of suitable alkali compounds that are available and evaluated as possible reference materials for the electron-probe microanalysis (EPMA) of alkaline niobates with a composition described by the general formula K_1–XNa_XNbO₃. The EPMA study verified that KNbO₃ and NaNbO₃ single crystals are stable under the electron beam and compositionally homogeneous. A quantitative microanalysis confirmed the composition of pure KNbO₃, while the NaNbO₃ crystal contained 0.3 mass fraction % of Ca. A significant improvement in the accuracy of the quantitative EPMA of polycrystalline potassium–sodium niobates was achieved using these single crystals as standards. The crystals can also be useful as reference materials for the analysis of sodium and potassium in other materials.
