Working Principle
The DTI-60T Automatic Graphite Digestion System uses controlled graphite heating technology combined with automated liquid handling and intelligent monitoring.
During operation:
1.Samples are placed into digestion vessels.
2.The automatic reagent system precisely adds acids according to the programmed method.
3.Non-contact mechanical mixing ensures uniform sample and reagent reaction.
4.Dual graphite heating modules provide accurate and independent temperature control.
5.Digestion proceeds under controlled heating conditions.
6.The system performs acid removal, cooling, and automatic volume adjustment.
7.The digested solution is ready for inorganic element analysis using techniques such as ICP-OES, ICP-MS, or AAS.
This automated workflow improves digestion consistency and reduces operator influence on analytical results.
