Digestion of Environmental Samples with PDC

Multiwave 7000 with its PDC (Pressurized Digestion Cavity) offers the opportunity to digest any kind of environmental sample for subsequent element analysis even within one run. PTFE-TFM, quartz and disposable vials can be used in the same digestion experiment enabling the simultaneous digestion of environmental samples with and without HF.

1 Introduction

Routine digestion and leaching of environmental samples, like soil, sediments, sludge, fly ash, etc. are among the most used applications in environmental chemistry.

In order to demonstrate the excellent suitability of Multiwave 7000 for sample preparation of environmental samples prior to element analysis the recovery rates of certified reference materials were determined based on EPA 3051A. The described conditions can be used as a starting point for different kind of environmental samples.
