Carbonate and Inorganic Carbon Analyzer
The CO-204 analyzes solid and liquid samples directly — no drying, grinding, or pretreatment required. Combining acid digestion with a high-sensitivity IR (NDIR) cell, the system delivers results in the 0–60% CO₂ range in under 3 minutes. The instrument stops automatically when the reaction is complete.
Measurement Principle
The CO-204 decomposes carbonates using sulfuric acid and measures the released CO₂ with a high-sensitivity NDIR cell. A Peltier cooler and anhydrone filter keep the gas stream completely dry before it reaches the detector.
Software
The integrated software handles calibration, analysis sequence management, and cell linearization from a single interface. All parameters are displayed in real time during the run.
Applications
Frequently Asked Questions
No. The CO-204 analyzes solid and liquid samples directly, with no pretreatment steps required. This capability significantly accelerates laboratory throughput.
CO₂ released by sulfuric acid digestion is transported to the IR cell by a nitrogen carrier gas and quantified by non-dispersive infrared (NDIR) absorption. The method maintains consistent precision at both low and high concentrations.
No. The Peltier cooler condenses moisture and acid vapors; the anhydrone filter then captures any remaining trace moisture. Only dry CO₂ reaches the IR cell — this design ensures long-term instrument reliability.
Yes. The dual measurement range (0–5% and 5–60% CO₂) handles both low-concentration slurry samples and samples approaching 100% carbonate content, such as limestone. Range selection is managed through the software.
