Microwave Digestion and Dissolution
The TIMS lab and the MC-ICPMS lab utilize an Anton-Paar Multiwave 7000 to dissolve samples before analysis. The Multiwave 7000 can digest food, environmental, polymer, cosmetic, pharmaceutical, geologic, chemical and petrochemical samples.
The Multiwave 7000 has a max temperature of 300 degrees Celsius and a max pressure of 199 bar. Along with low temperature/pressure capabilities, the high temperature/pressure capabilities can dissolve refractory materials such as:
- ceramics
- carbon
- ores
- minerals (including zircon)
- alloys
- steel
- petrochemicals
- polymers
Currently, 18 different samples (up to 1 gram per sample) can be dissolved at a time using HF, HNO3 or reverse aqua regia in PTFE-TFM vials. Typical dissolution times range from 1-2 hours.
