Ø Working Principle
The samples are combusted with oxygen and water vapor in the combustion furnace unit, and the resulting gaseous compounds are absorbed by the absorption solution. The analytes dissolved in the absorption solution are then transferred to the ion chromatography system for determining the concentrations of halogens (fluoride, chloride, bromide, iodide) and sulfur.
Highlights
1.High automation
①System preparation: With one-key activation, the combustion furnace automatically heats up, and the IC module starts automatically.
②Sample introduction: Place the sample in the autosampler, input the required sample information and analytical method. The system will then automatically perform combustion pyrolysis according to the preset program.
③Analysis: The sample solution is automatically made up to volume and injected into the IC module, with the flow path automatically cleaned. Automatic dilution is optional for high-concentration samples.
④Results are automatically calculated, and blank values are automatically deducted.
⑤Fault Handling: The system automatically prompts for faults and provides troubleshooting methods. Individual components can be tested separately via the manual detection interface.
2.Wide sample compatibility
①Supports solid, liquid, and gas samples.
②Pyrolysis atmospheres can be selected according to specific needs, including oxygen, air, argon, nitrogen, and water vapor.
③Fully configurable combustion-pyrolysis parameters, including sample introduction time, sample introduction distance, retention time, and water vapor flow rate.
3.High efficiency
①Simultaneous sulfur and halogens determination, with automatic data calculation and direct LIMS upload minimizes manual errors.
②Calibration curves for various concentration ranges can be prepared to reduce repetitive testing.
4.Wide measuring range, low quantitation limit
Based on a 50mg sample, the limit of quantitation (LOQ) up to 0.2 mg/kg(200ppb). Theoretically, the maximum concentration can be up to 100%.
5.Easy maintenance and disassembly
①Modular design enables easy replacement of combustion tubes, sampling rods, and chromatographic columns.
②Sundy C-IC system can be used independently as a combustion-pyrolysis furnace or an ion chromatography.
