Digestion of Environmental Samples for Element Analysis with ICP

The Multiwave 7101/7301//501 series offers the opportunity to digest any kind of environmental sample for subsequent element analysis within one run.

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 suitability of Multiwave 7101/7301 as well as Multiwave 7501 for sample preparation of environmental samples prior to element analysis, the recovery rates of certified reference materials were determined based on EPA 3051A. The materials were digested with inverse aqua regia in Multiwave 7000 and with regular aqua regia in Multiwave 7501. For both systems easy-to-use pressure-sealed vials were used.

The described conditions can be used as a starting point for different kinds of environmental samples.
