Ailun YC9000 Intelligent Ion Chromatograph

Overview

The Ailun YC9000 Intelligent Ion Chromatograph is a high-performance, modular benchtop system engineered for precise, reproducible separation and quantitative detection of anions and cations in complex aqueous matrices. Based on suppressed conductivity detection and high-pressure eluent delivery, the YC9000 implements classical ion exchange chromatography principles—utilizing chemically stable, high-capacity ion-exchange columns coupled with a continuous electrochemical suppressor to enhance sensitivity and reduce background conductivity. Its architecture integrates core fluidic components—including dual-channel high-precision PEEK piston pumps, a six-port injection valve, thermostatically controlled column compartment, membrane-based suppressor, and temperature-stabilized conductivity cell—into a compact, low-dead-volume manifold. This design minimizes extra-column band broadening, thereby improving resolution, lowering baseline noise (<0.5 nS), and achieving sub-ppb detection limits for common inorganic ions (e.g., F⁻, Cl⁻, NO₂⁻, PO₄³⁻, SO₄²⁻, Na⁺, NH₄⁺, K⁺) under optimized conditions.

Key Features

• Modular functional architecture enabling flexible configuration of dual independent detection channels (anion/cation or parallel dual-anion), each supporting conductivity, amperometric, or UV/Vis detection modules;
• Intelligent MT (Modular Tracking) technology: auto-identification of connected modules, automatic parameter optimization (e.g., flow rate, suppression current, temperature setpoints), and secure logging of operational history with timestamped metadata for GLP-compliant audit trails;
• Integrated gas management: built-in positive-pressure degassing unit with rapid CO₂ extraction capability, significantly reducing baseline drift induced by carbonate equilibria in alkaline eluents (e.g., KOH, NaOH);
• On-line liquid-gas separator eliminating dissolved O₂ and CO₂ without external helium sparging—ensuring stable baseline and consistent retention time reproducibility (RSD < 0.15% over 24 h);
• Full PEEK/PTFE wetted path: all fluid-contact surfaces—from pump heads and tubing to columns, suppressors, and detector cells—are fabricated from inert, metal-free polymers, ensuring compatibility with acidic, basic, and organic-modified eluents (up to 40% ACN) and preventing trace metal leaching during biological or ultrapure water analysis;
• Thermostatic control system with ±0.1 °C stability across 5–65 °C range, supporting isocratic and gradient elution protocols with programmable ramp rates;
• High-pressure capability (up to 42 MPa) accommodating sub-2 μm particle-packed columns and enabling ultra-fast separations with enhanced peak capacity.

Sample Compatibility & Compliance

The YC9000 supports direct injection of filtered aqueous samples including drinking water, wastewater, semiconductor process rinse water, pharmaceutical excipients, food extracts, and environmental soil leachates. It complies with key international method standards including ASTM D4327 (anions in water), ISO 14911 (determination of cations/anions in water), and USP (conductivity of purified water). The system’s electronic logbook, user-access-level permissions, and full audit trail functionality align with FDA 21 CFR Part 11 requirements for electronic records and signatures when deployed in regulated QC/QA environments. All hardware components meet IEC 61000-4 electromagnetic immunity specifications, ensuring robust operation in shared laboratory infrastructure.

Software & Data Management

Control and data acquisition are managed via Ailun IC-Studio v3.x software—a Windows-based platform supporting real-time instrument monitoring, method development, sequence scheduling, and multi-channel chromatogram overlay. The software provides automated peak integration with intelligent recognition of solvent fronts, tailing peaks, shoulder peaks, and co-elutions using adaptive baseline algorithms. Quantitative workflows include single-point calibration, multi-level linear/nonlinear curve fitting (with weighting options), internal standard correction, and batch report generation compliant with LIMS export formats (CSV, XML, PDF). Raw data files are stored in vendor-neutral HDF5 format with embedded metadata (instrument ID, operator, method version, calibration status), facilitating long-term archival and third-party reprocessing. Remote access and centralized fleet management are supported via optional Ethernet-enabled network deployment.

Applications

The YC9000 serves diverse analytical needs across regulated and research settings: routine anion/cation profiling in municipal water quality labs (per EPA Method 300.1 and ISO 10304-1); trace halide and perchlorate quantification in pharmaceutical raw materials; organic acid analysis (e.g., acetate, formate, citrate) in bioprocess monitoring; fluoride and nitrate screening in agricultural runoff; lithium, sodium, and potassium determination in battery electrolyte formulations; and chloride ingress testing in concrete pore solutions per ASTM C1218. Its dual-channel capability allows simultaneous monitoring of anionic impurities and cationic counterions in conductive polymer synthesis or catalyst characterization workflows.

FAQ

Does the YC9000 require external gas sources for degassing?
No—its integrated positive-pressure degassing module and on-line liquid-gas separator eliminate the need for helium or nitrogen sparging.

Can the system operate with both anion and cation columns simultaneously?
Yes, via dual independent flow paths and configurable detector modules; each channel can be independently optimized for eluent chemistry, flow rate, and detection mode.

Is the software validated for use in GMP-regulated laboratories?
IC-Studio v3.x includes 21 CFR Part 11 compliance features (electronic signatures, audit trail, role-based access), and validation documentation packages are available upon request for IQ/OQ/PQ execution.

What maintenance intervals are recommended for the electrochemical suppressor?
Under typical usage (≤20 injections/day with 20 mM KOH eluent), the suppressor demonstrates >2,000 hours of stable operation; performance verification is performed automatically during startup via conductivity baseline assessment.

Are application notes and certified reference methods provided?
Yes—Ailun supplies method transfer kits, certified calibration standards (NIST-traceable), and peer-reviewed application briefs covering >35 industry-specific workflows, including EPA, ASTM, and pharmacopeial methods.
