Mineralisation of sludges, soils and plants samples by microwave technique
Microwave owen ANTON PAAR
- It is equipped with microwave generators (magnetony), which generate microwaves at a frequency of 2.45 GHz, causing direct heating of samples
- This provides a quick and full digestion of organic and inorganic samples by high pressure and temperature
- The area of application is high-resolution wet samples prior to determination of trace elements in their technique AAS, ICP-AES or ICP-MS, performed during the environmental analysis, food, beverages, chemical and petrochemical industry
