WAYEAL IC6500 Multi-Functional Ion Chromatograph

Overview

The WAYEAL IC6500 Multi-Functional Ion Chromatograph is a high-integrity, benchtop analytical system engineered for precise, reproducible separation and quantification of inorganic anions and cations in diverse aqueous matrices. Built upon suppressed conductivity detection principles, the IC6500 employs a dual-conductivity detector architecture—comprising both conventional and microbore flow cells—to deliver enhanced sensitivity and dynamic range across wide concentration spans (sub-ppb to ppm levels). Its core separation mechanism relies on ion-exchange chromatography with gradient or isocratic elution, supported by an integrated on-line electrolytic eluent generator (OEG) that synthesizes high-purity KOH, methanesulfonic acid (MSA), or other compatible eluents directly from deionized water and precursor salts—eliminating manual eluent preparation, reducing baseline drift, and improving long-term retention time stability. The system’s fully PEEK fluidic path ensures chemical inertness toward aggressive eluents and sample matrices, minimizing metal leaching and adsorption artifacts critical for trace-level analysis.

Key Features

• Integrated On-Line Electrolytic Eluent Generator (OEG): Enables automated, high-purity eluent synthesis for both anion (KOH) and cation (MSA) modes—reducing contamination risk and enhancing method robustness.
• Dual Conductivity Detection System: Combines standard and low-volume flow cells to optimize signal-to-noise ratio for both high- and low-concentration analytes without hardware reconfiguration.
• Full-PEEK Fluidic Architecture: All wetted components—including pump heads, injection valve, column oven, and detector cell—are constructed from biocompatible, corrosion-resistant PEEK polymer, ensuring compatibility with strong alkaline or acidic eluents and preventing metal-induced column degradation.
• High-Pressure Capability (42 MPa): Supports use of sub-2 µm particle-packed columns and capillary-format columns for improved resolution, peak capacity, and analysis speed.
• Thermostatically Controlled Column Compartment: Maintains precise temperature control between 5 °C and 70 °C (±0.1 °C), essential for retention time reproducibility and method transferability across laboratories.
• Modular Hardware Design: Allows flexible configuration with optional accessories—including autosamplers, post-column reaction modules, suppressor regeneration units, and UV/visible detectors—for expanded application scope and future scalability.

Sample Compatibility & Compliance

The IC6500 is validated for analysis of environmental waters (drinking, surface, wastewater), food extracts, pharmaceutical excipients, battery electrolytes, semiconductor process chemicals, and biological fluids (after appropriate sample pretreatment). It supports ASTM D4327, ISO 14911, EPA Methods 300.0, 300.1, and 317.1 for anion analysis; and EPA Method 318.1 and ISO 15207 for cation determination. The system architecture conforms to GLP/GMP data integrity requirements when paired with compliant chromatography data systems (CDS), supporting audit trails, electronic signatures, and 21 CFR Part 11–compliant user access controls via optional software licensing.

Software & Data Management

Controlled via WAYEAL Chromatography Suite v3.x—a Windows-based platform compliant with ICH M10 and FDA guidance on analytical procedure validation—the IC6500 provides full instrument control, sequence management, real-time chromatogram visualization, peak integration with customizable baselines, and automated calibration curve generation. Raw data are stored in vendor-neutral .cdf format (compatible with OpenLab CDS, Chromeleon, and Empower), and report templates adhere to ISO/IEC 17025 documentation standards. Audit trail functionality records all parameter changes, method edits, and result modifications with timestamped user attribution.

Applications

• Environmental Monitoring: Quantification of F⁻, Cl⁻, NO₂⁻, Br⁻, NO₃⁻, PO₄³⁻, SO₄²⁻, and Li⁺, Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺ in municipal water supplies and industrial effluents.
• Pharmaceutical Quality Control: Testing of counterions in active pharmaceutical ingredients (APIs), residual acetate or chloride in lyophilized formulations, and ionic impurities per ICH Q2(R2) and USP .
• Food & Beverage Safety: Detection of preservative anions (benzoate, sorbate), nitrate/nitrite in cured meats, and cationic nutrients (Na⁺, K⁺, Ca²⁺) in fortified beverages.
• Electrochemical Materials: Analysis of PFOS/PFOA precursors, sulfate impurities in lithium-ion battery catholytes, and fluoride content in solid-state electrolyte slurries.
• Academic & Method Development Labs: Platform for developing novel multi-dimensional IC methods, coupling with mass spectrometry (IC-MS), or validating new stationary phases under controlled thermal and pressure conditions.

FAQ

Does the IC6500 support both anion and cation analysis on a single platform?
Yes—the system is natively configured for dual-mode operation using interchangeable ion-exchange columns and corresponding eluents generated on-line via the OEG module.
Is the full-PEEK flow path compatible with potassium hydroxide eluents at concentrations up to 100 mM?
Yes—PEEK exhibits excellent chemical resistance to concentrated KOH solutions across the full operating temperature range (5–70 °C), with no measurable degradation over 2,000 hours of continuous exposure.
Can the dual conductivity detector be used simultaneously for two independent channels?
No—it operates in alternating or parallel acquisition mode within a single analytical run to maximize sensitivity across differing analyte concentrations, not as two independent detectors.
What regulatory documentation is provided for IQ/OQ/PQ qualification?
WAYEAL supplies standardized qualification protocols, factory test reports, and raw data logs aligned with ASTM E2500 and EU Annex 15, enabling seamless installation and operational qualification in regulated environments.
Is remote monitoring and control supported?
Yes—via secure HTTPS-enabled web interface and OPC UA integration, allowing real-time status checks, alarm notifications, and limited parameter adjustments from external network nodes compliant with ISO/IEC 27001 security policies.
