Digestion of Coal and Graphite Samples for Element Analysis with ICP

Rotor 20SVT50 in Multiwave 5000 allows the digestion of demanding, highly reactive samples such as coal, coke and graphite, which require high temperatures, with the convenience and safety of the SmartVent technology.

Carbon-rich samples such as coal, coke and graphite are a challenge regarding closed vessel acid digestion: the temperature required for a complete digestion increases with the grade of mineralization from charcoal to graphite. In the past, microwave acid digestion of graphite was only possible with highest performance rotors like Rotor 8NXF100.
In addition the large amount of reaction gases generates high pressure and requires fast pressure control to keep the highly exothermic reactions under control.
