AELAB Ion Chromatograph OIC-M1 | Precise Ion Analysis Instrument

The AELAB OIC-M1 Ion Chromatograph is a high-performance analytical instrument designed for precise ion analysis. It features a modular built-in eluent generator that supports various types of elution, including hydroxyl, carbonate bicarbonate mixed, and methylsulfonic acid types. The system enables both isocratic and gradient elution by simply adding pure water and electrochemically generating the desired eluent concentration (0-100 mmol/L), with a flow rate of 0-5 ml/min and concentration accuracy of 0.1 mM/L. This ensures flexibility and reliability for different ion analysis needs.

Features:

• Modular Eluent Generator: Capable of producing the required concentration of eluent through electrolysis, allowing for easy isocratic and gradient elution.
• High Pressure Online Degassing: Prevents air bubbles from destabilizing the pump and causing wear, ensuring smooth flow path operation.
• Negative Pressure Degasification: Online degassing with high efficiency (≥90%), preventing the formation of air bubbles that could compromise the system’s performance.
• Advanced High-Pressure Pump: A double plunger pulse series pump made from PEEK material, capable of withstanding pressures up to 42MPa (6000psi) and supporting flow ranges from 0-9.999 ml/min for reliable sample analysis.
• Electronically Controlled Sampling Valve: A six-way valve with automatic control by the host computer, capable of handling over 100,000 switching cycles for long-lasting performance.
• Continuous Regeneration Suppressor: Features continuous micromembrane electrical suppression technology with the option for self-regeneration or external regeneration fluids, providing excellent suppression with a capacity of ≥200μeq and volume ≤50μL.
• Universal Conductivity Detector: Equipped with a high-quality conductivity detector with a detection limit as low as 0.001μg/ml for CL and 0.0005μg/ml for Li+, ensuring accurate and repeatable results. The detector offers a linearity of r > 0.999, baseline noise ≤0.0005μS, and minimal baseline drift (≤0.01μS/30min).
• Leakage Alarm and Automatic Cleaning: Equipped with leakage alarms for the generator, pump, valve, pipeline, and other flow path components, and the ability to automatically clean the pump after experiments to maintain system integrity.
• Overpressure and Pressure Monitoring: Monitors both high and low pressure, with overpressure alarms to prevent damage to the system and optimize performance.

🔬 How It Works?

The AELAB OIC-M1 operates by electrochemically generating eluents with a modular built-in generator, allowing for precise isocratic or gradient elution tailored to your ion analysis needs. The system continuously monitors pressure and eluent concentration in real-time to ensure stable flow and reliable separation. Its advanced degassing units prevent air bubbles from interfering with the flow path or pump operation. Samples are injected via an electronically controlled six-way valve, while continuous regeneration suppressors eliminate ionic interference. The high-sensitivity conductivity detector accurately measures ion concentrations, delivering repeatable and dependable results for complex analyses.
