Based on the earlier described pressure ashing device [1], a modified system is described for a complete HF-ashing technique of silicate matrices like soils, sediments and sludges. Using graphite fortified PTFE material in combination with pure PTFE sample containers, it is possible to apply a mixture of HNO3/HF for ashing in the closed pressure ashing apparatus. This technique was tested with several standard reference materials. The advantage of the new system is a considerable saving of time, freedom of contamination and element losses in comparison to the open techniques.
