Overview
The Ailun YC988 Portable Ion Chromatograph is a field-deployable analytical instrument engineered for quantitative and qualitative determination of common anions (e.g., F⁻, Cl⁻, NO₂⁻, Br⁻, NO₃⁻, PO₄³⁻, SO₄²⁻) and cations (e.g., Li⁺, Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺) in aqueous matrices. It operates on the principle of suppressed conductivity detection following ion-exchange separation—where analytes are resolved on a high-efficiency, low-capacity ion-exchange column under precisely controlled eluent composition and flow conditions. Designed specifically for mobile laboratory applications, environmental monitoring, emergency response, and on-site water quality assessment, the YC988 integrates miniaturized high-pressure fluidics, thermal stabilization architecture, and intelligent power management to maintain analytical integrity outside fixed-lab environments. Its compact footprint (≤38 cm × 28 cm × 18 cm), low mass (6 hours under typical analytical duty cycles.
Key Features
- Miniaturized High-Pressure Constant-Flow Pump: Incorporates cam-driven dual-piston architecture with active pulse damping; achieves flow stability ≤0.1% RSD at 1.5 mL/min across 0.001–9.999 mL/min range while maintaining pressure tolerance up to 25 MPa.
- Intelligent Post-Valve Thermal Management System: Actively regulates temperature of detector cell, suppressor, and post-column tubing within ±10 °C reproducibility over 0–35 °C ambient range—critical for retention time stability and peak shape fidelity during uncontrolled outdoor deployments.
- Automated System Maintenance Protocol: Includes real-time plunger seal rinsing during high-salt eluent operation (e.g., ≥30 mM KOH/K₂CO₃), programmable post-run column flushing sequences, and configurable idle-state power-down logic to extend pump lifetime and reduce manual intervention.
- Integrated Power Optimization Module: Dynamically scales CPU clock frequency, detector gain, and heater duty cycle based on operational mode—reducing average power draw by ~40% compared to conventional portable IC platforms without compromising baseline noise (<0.5 nS) or detection sensitivity (sub-ppb Cl⁻ LOD).
- Ruggedized Mechanical Design: Aluminum alloy chassis with IP54-rated enclosure; shock-absorbing mounting for separation column and conductivity cell; vibration-tolerant optical path alignment for detector stability during transport.
Sample Compatibility & Compliance
The YC988 accepts clarified, filtered (0.45 µm nylon or PVDF membrane), and pH-adjusted aqueous samples—including drinking water, surface water, wastewater effluents, soil leachates, and industrial process streams. It supports both carbonate/bicarbonate and hydroxide-based eluents (0.1–60 mM concentration range) with compatibility for chemical suppression (e.g., MM4–MM6 series suppressors) or electrolytic suppression modules (optional upgrade). The system adheres to core performance expectations outlined in ISO 10304-1:2012 (determination of dissolved anions by liquid chromatography), ASTM D4327 (standard test method for anions in water by IC), and EPA Method 300.1 (determination of inorganic anions by IC). Data acquisition and reporting workflows are structured to support GLP-compliant documentation requirements, including user-defined audit trails and electronic signature-ready report templates.
Software & Data Management
Controlled via Ailun IC-Studio v3.2 (Windows 10/11 compatible), the software provides real-time chromatogram visualization, multi-point calibration curve generation (linear, quadratic, or weighted), peak integration with customizable baselines, and automated report export in PDF, CSV, and XML formats. All acquisition parameters—including flow rate, gradient profile, detector gain, and temperature setpoints—are logged with timestamped metadata. The system supports 21 CFR Part 11–compliant user access levels (Administrator, Analyst, Reviewer), electronic logbooks with immutable entries, and encrypted local database storage. Optional cloud synchronization enables remote instrument status monitoring and centralized method library deployment across distributed field units.
Applications
- Field-based compliance monitoring for municipal drinking water per WHO/GB 5749–2022 guidelines
- Rapid screening of nitrate/nitrite contamination in agricultural runoff and groundwater
- On-site verification of desalination plant brine discharge composition
- Emergency response analysis for accidental chemical releases (e.g., chloride spikes from road deicers, sulfate anomalies from mining effluents)
- Quality control of pharmaceutical excipients and purified water in GMP manufacturing environments
- Educational use in university analytical chemistry laboratories emphasizing method development and mobile instrumentation principles
FAQ
What eluent types are supported by the YC988?
The instrument is compatible with potassium hydroxide (KOH), sodium carbonate (Na₂CO₃), sodium bicarbonate (NaHCO₃), and methanesulfonic acid (MSA) eluents across concentrations from 0.1 mM to 60 mM.
Does the YC988 meet regulatory data integrity requirements?
Yes—the embedded IC-Studio software supports ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate) and includes features aligned with FDA 21 CFR Part 11, including role-based access control, electronic signatures, and audit-trail generation.
Can the YC988 operate continuously on battery power?
Under standard operating conditions (1.5 mL/min flow, 25 °C column temperature, conductivity detection), the integrated Li-ion battery supports ≥6 hours of continuous analysis before recharge.
Is column oven temperature control available?
The YC988 does not include a dedicated column oven; instead, its intelligent post-valve thermal management stabilizes detector and suppressor temperature, ensuring retention time repeatability even when ambient temperatures fluctuate between 0–35 °C.
What maintenance intervals are recommended for field use?
Plunger seals should be inspected every 200 hours of pump runtime; suppressor cartridges require replacement every 1,500–2,000 injections depending on eluent strength and sample matrix complexity; annual calibration verification against NIST-traceable standards is advised.
