Retsch mills can grind soils either wet or dry.
Soil much like other samples, requires size reduction and homogenisation prior to subsequent analytical methods. Contamination from the grinding process is apparent.
Unknown contaminants from the milling process
When using a range of heavy metals free accessories and powerful wear resistant ceramics, grinding can be performed with peace of mind. No need to second guess unknown contaminants from the milling process.
Retsch has mills that can be used to grind soils either wet or dry.
With these machines there is no need to change the sample by heating or time related decomposition of analytes.
You can choose from open or closed types of milling.
Closed vessel milling reduces the chance of inhalation of soil compounds or toxic substances.
High throughput solutions for either batch or continues size reduction of various types of soil and rock are also available.
Sample preparation of soils
From the analysis of heavy metals or volatile components such as dioxin and furan to the determination of the clay content or the ascertainment of fertilizing requirements, Retsch’s crushers and grinders as well as the sieve shakers are the products of choice.
