Atomic absorption spectroscopy (AAS), in both flame and furnace graphite mode, is one of the best methods for determination of the metal concentrations in various specimens that are dissolved in acid. Mineralization and dissolution of samples are the vital steps in many procedures, especially in the case of low-metal concentrations. The technique can be applied for impurity tests for trace metals as well as for assay of various commonly occurring elements in pharmaceuticals.
AA240Z Zeeman Furnace Grafite Agilent and 55B Flame Atomic Absorption Agilent
Based on the sensitive AC-modulated Zeeman technique, which is proven to give the best detection limits of any Zeeman spectrometer, the Agilent 240Z AA with up to 4 fixed lamp positions offers the highest sensitivity, performance and simplicity of operation. The instrument is supplied with the GTA 120 Zeeman graphite tube atomizer for superior graphite furnace performance. The furnace and flame are controlled by Agilent Worksheet Software with only one PC, which minimizes training by delivering rapid instrument set-up, easy operation, and simple method development. In this way you can have the widest linear dynamic range, from sub parts-per-billion to percent levels, allowing analysis of any sample. Dedicated atomizers eliminate setup and changeover times.
