Instrument Details
Instrument/Facility Name: Microwave digestion system
Make                                   : Milestone S.R.L., Italy
Model                                  : MILESTONE ETHOSEASY
Specification   :

Click to ViewMicrowave Digestion System used for applications for closed vessel digestion of environmental and industrial samples like soil, sediments, rocks, plants, sludge, coal fly ash, manures, waters, sewage and sludges etc. using all major acids like HNO3, HCl, H2O2, HF, H2SO4, etc. for further analysis in spectrophotometer, AAS, MP-AES and ICP-MS etc.

  Working Principles
Click to ViewOrganic material is digested by heating sample in the presence of concentrated acid up to a temperature of 180-200 C in a microwave field. This destroys all organic matter present in the sample and minerals are solubilized. This solution is used for estimation of minerals by atomic absorption spectrometry or ICP-OES or MP-AES. The system has got 2 magnetrons which is responsible for generation of microwave energy. Both the magnetrons work simultaneously. The wave guide and diffuser fan ensure uniform distribution of energy throughout the cavity.

  Applications
  User Instructions
For digestion of any materials (plant, soil, manure, sediments, food, feed, rock samples etc.). The microwave power rating is 1900 Watts. The cavity size is 70 litres. Samples should be finely ground. Sample size upto 0.5 g and acid volume, minimum 5 ml and maximum 25 ml.
