Evaluation of a New Forked Platform Design for Graphite Furnace AAS Authors

چکیده
Graphite furnace techniques are characterized by excellent analytical sensitivity. They are methods of choice for the determination of trace elements in various environmental, biological, and clinical samples. However, they can be plagued by chemical and background interferences which complicate methods development and sample analysis. Using the graphite platform technique, these interferences can be reduced. The graphite platform is placed in the graphite tube. Sample atomization takes place from the platform rather than the tube wall. The temperature of the platform lags behind the temperature of the tube wall and the gaseous environment. This temperature lag causes delayed sample vaporization and analyte atomization. This can reduce chemical and background interferences.
