Applications

Technical Specifications

Analytical Method and Hydrolysis Operation

The analytical workflow of this system relies on the high-temperature combustion hydrolysis principle. When solid materials such as coal, cement meal, or silicate ores are heated between 1100°C and 1200°C in the presence of water vapor and oxygen, fluoride compounds hydrolyze cleanly into hydrogen fluoride (HF) gas. The vapor-phase effluent is directed into a condensation and absorption system where fluorine is quantitatively collected into an aqueous solution within 15 minutes.

Once condensation is complete, fluoride concentration can be determined immediately via the integrated digital ion meter utilizing an ion-selective electrode (ISE) or through standard titration. The included PC software captures the resulting millivolt or titrant volumetric values, automatically executing blank corrections, calibration curve cross-referencing, and mass-fraction calculations to deliver compliant laboratory data without manual mathematical handling.
