Microwave Digestion in the field of Environmental Analysis
With reference to relevant legal norms
As sustainability is getting more and more important in everyday's life, environmental analyses are getting more important, as well. For many of these analyses, there are standardized processes that fullfil legal requirements and norms. When it comes to sample preparation for environmental analyses, often, the norms require microwave digestion processes. Therefore, all important information on microwave digestion in the field of environmental analysis can be found on this site. The information include amongst others application reports according to legal norms and detailed descriptions of the Berghof microwave digestion systems.
The following norms and methods are described in more detail below:
