Quali-IC™ 3200 Operating Principle
Instead of soaking solid test materials in harsh, dangerous acids for hours, the Combustion Ion Chromatograph Quali-IC™ 3200 (Online) pushes your sample batches through an automated heating pipeline to convert solid, liquid, or gas matrices into clean, measurable solutions.
1. Thermal Oxidation & Pyrolysis
The system begins by subjecting your samples to extreme thermal destruction, leaving no unburned soot inside the reaction tube:
- Multi-Zone Heating: Five independently controlled heating stages push thermal boundaries all the way to a blazing 1200°C.
- Complete Breakdown: This extreme, white-hot heat completely tears apart tough, carbon-chained materials without causing any annoying sample splashing.
- Oxygen Purging: Any unburned residue is pushed right back into the central reaction zone using reverse oxygen scavenging, guaranteeing absolute thermal breakdown.
2. Hydropyrolysis & Gas Conversion
As the samples burn, a controlled stream of moisture flows into the furnace (a chemical process known as hydropyrolysis). This moisture injection ensures that:
- Tricky elements convert into highly soluble gaseous states.
- Fluorine and sulfur form simple, easily trapped gases rather than fusing into a stubborn, glass-like slag that would otherwise escape liquid measurement.
3. Gas Condensation & Absorption
Every single milliliter of solution that enters your liquid analyzer is incredibly pure. To capture target elements perfectly in the liquid trap, the system relies on fast Peltier chilling:
- Peltier Cooling: The system swiftly drops the scorching hot gas temperatures to 5°C to prevent volatile chemical loss.
- High Absorption: This fast thermal drop ensures that the resulting gases dissolve completely into the liquid receiving bath, providing satisfyingly spot-on consistency.
4. Ion Separation & Detection
Finally, the newly absorbed liquid flows directly into the internal liquid separator. To keep your workflow moving, the analysis utilizes a continuous method:
- Parallel Processing: The furnace starts torching the next sample while the built-in separator is still reading the current one, clearing out slow laboratory bottlenecks.
- Interference Elimination: Inline scrubbing wipes away annoying interferences (like carbon dioxide or nitrates) before they hit the detector, leaving your results clear.
- Trace Enrichment: If you are dealing with insanely low concentrations, optional ion enrichment columns pump up the sensitivity to catch the tiniest trace components, and the overall analytical reliability is sheer perfection.
