Abstract
A digestion procedure for silicate containing matrices like soil, sludge, etc. by using a commercially available pressure ashing device (Seif-Aufschlubetatechnik, Germany) with PFA (perfluoroalkoxy) sample vessels is described at the results for different matrix- and trace elements in different suitable certified standard reference materials. The advantages of this technique compared with the use of Teflon(R)-(PTFE, polytetrafluoroethylene) vessels and the open treatment in Pt-crucibles will be discussed.Entities:
