Проблемы разработки новых национальных стандартов на методы анализа благородных металлов и их сплавов

A review of the currently effective Russian national standards for methods of platinum metal and alloy analysis has been made, many of the standards being obsolete as for their content and the analytical procedures used. Some problems of the development of the new national standards have been described and the way of problem solving has been suggested.Приведен обзор действующих национальных стандартов на методы анализа благородных металлов и их сплавов, многие из которых устарели не только по форме и содержанию, но и по существу используемых методик анализа. Рассмотрены проблемы и предложены пути разработки новых национальных стандартов

Prospects in Analytical Atomic Spectrometry

Tendencies in five main branches of atomic spectrometry (absorption, emission, mass, fluorescence and ionization spectrometry) are considered. The first three techniques are the most widespread and universal, with the best sensitivity attributed to atomic mass spectrometry. In the direct elemental analysis of solid samples, the leading roles are now conquered by laser-induced breakdown and laser ablation mass spectrometry, and the related techniques with transfer of the laser ablation products into inductively-coupled plasma. Advances in design of diode lasers and optical parametric oscillators promote developments in fluorescence and ionization spectrometry and also in absorption techniques where uses of optical cavities for increased effective absorption pathlength are expected to expand. Prospects for analytical instrumentation are seen in higher productivity, portability, miniaturization, incorporation of advanced software, automated sample preparation and transition to the multifunctional modular architecture. Steady progress and growth in applications of plasma- and laser-based methods are observed. An interest towards the absolute (standardless) analysis has revived, particularly in the emission spectrometry.Comment: Proofread copy with an added full reference list of 279 citations.
