- No wetchemical sample preparation - No dilution errors or analyte losses - Reliable digestion solid AA – direct solids analysis technique for graphite furnace AAS The solid AA technology enables direct solid analysis without elaborate sample preparation. Solid, pasty or viscous substances are automatically or manually transferred directly into the graphite tube. Heterogeneous samples are only ground and homogenized before analysis. The decomposition of the sample matrix by means of an acid digestion is replaced by the temperature program of the graphite furnace. Combined with a powerful background correction, the interference-free and precise determination of almost all elements in numerous materials is possible. The graphite furnace technique is subject to few interferences caused by the sample matrix. Therefore, even liquid calibration standards may be used in most cases. A calibration with solid matrix reference materials, which are expensive and often not available in the correct composition, is usually not necessary. The Analytik Jena graphite furnace systems can be converted from liquid to solids analysis in just a few minutes - the unlimited use of both techniques is guaranteed. All functions are integrated in the operating software. Additional modules are not required. Easy, software-guided routines allow a simpler adjustment of the autosamplers and guarantee a reliable sample supply.
