The Thermo Finnigan EA112 Elemental Analyser
Instrument: Thermo Finnigan EA112 Elemental Analyser
How it works
- Solid samples are combusted at temperatures exceeding 900ºC with a flow of pure oxygen.
- The resulting oxides of carbon (C), hydrogen (H) and nitrogen (N) are analysed chromatographically.
Run times can be as little as 10 minutes for C, H, N analysis and only small sample masses are required (5-20mg).
Examples of samples:
- Nickel ores
- Coal and lignite
- Carbonate rocks
