Einsatz des Hochdruckveraschers HPA nach Knapp [1] für die voltammetrische Bestimmung von Spurenelementen in biologischem Material.
Application of the high-pressure ashing system HPA according to Knapp [1] for voltammetric determinations of trace elements in biological material.
Fresenius Z. Anal. Chem. 326, 142-145 (1987)
On the basis of the high temperature and high pressure available in the "High Pressure Ashing System (HPA)", this new device was tested for ashing biological material for a subsequent analytical determination of trace elements by voltammetric techniques, especially DPASV. By means of different standard reference materials it could be shown that this wet ashing technique is very suitable for this analytical method for which a complete destruction of organic material is one of the most important requirements. The application of a mixture of HNO3 and a small amount of HClO4 and the use of different temperature programmes allows a very satisfactory destruction of different organic materials. The results for various materials and for some trace elements and the blank values of the procedure are given.
