Overview
The Dionex ICS-2000 is a benchtop ion chromatography (IC) system engineered for high-resolution, reproducible separation and quantification of anions and cations in complex aqueous matrices. Built on Thermo Fisher Scientific’s legacy platform following its acquisition of Dionex in 2011, the ICS-2000 integrates a dual-piston reciprocating pump with chemically inert PEEK fluidic pathways, enabling full compatibility across pH 0–14 and with organic modifiers such as methanol (up to 25% v/v for anion analysis). Its core architecture supports both suppressed and non-suppressed conductivity detection, with optional electrolytic eluent generation (EG) for gradient-free, low-background operation. The system is designed for routine compliance-driven environments—particularly environmental, pharmaceutical, and food safety laboratories—where robustness, method transferability, and long-term operational stability are critical.
Key Features
- Chemically resistant PEEK pump heads and flow paths ensure compatibility with aggressive eluents and extended service life under continuous use.
- Microprocessor-controlled dual-piston pump delivers precise flow rates from 0.05 to 5.0 mL/min in 0.01 mL/min increments, with flow accuracy ±0.1% and precision <0.1% RSD.
- Integrated column oven maintains temperature between ambient +5°C and 60°C, with stability of ±1°C and accuracy of ±2°C at 40°C—critical for retention time reproducibility.
- Digital conductivity detector features temperature-compensated measurement (1.7%/°C), <1 µL cell volume, and a linear dynamic range up to 15,000 µS, supporting both trace-level and high-concentration analyses.
- Electrolytic eluent generator (EG) option enables on-demand production of KOH (anion) or MSA (cation) eluents at concentrations ranging from 0.1 to 100 mM, eliminating manual eluent preparation and reducing baseline drift.
- Onboard suppressor power supply supports both AESR (0–150 mA) and SRS (0–500 mA) configurations, allowing flexible integration with various anion and cation suppressors.
- Full system control via Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS) software—including method development, sequence execution, real-time monitoring, and audit-trail-enabled reporting compliant with 21 CFR Part 11 requirements.
Sample Compatibility & Compliance
The ICS-2000 accommodates a broad spectrum of sample types, including drinking water, wastewater, soil extracts, biological fluids, pharmaceutical excipients, and food leachates. Its wide pH and solvent tolerance permits direct injection of samples containing up to 25% methanol (for anion analysis) without post-column dilution or derivatization. The system meets key international standards for ion analysis, including ASTM D4327 (anions in water), ISO 10304-1 (determination of dissolved anions), and USP (conductivity of purified water). When operated with validated methods and Chromeleon CDS under configured 21 CFR Part 11 settings—including electronic signatures, user access controls, and immutable audit trails—the instrument satisfies GLP and GMP documentation requirements for regulated QC/QA laboratories.
Software & Data Management
Control and data acquisition are fully managed through Chromeleon CDS v7.x or later. The software provides intuitive method setup, automated calibration curve generation, peak integration with customizable baselines, and export to CSV, PDF, or LIMS-compatible formats. All instrument parameters—including pump pressure, detector response, column temperature, and suppressor current—are logged with timestamps and user attribution. Audit trail functionality records every change to methods, sequences, or results, ensuring full traceability for internal audits or regulatory inspections. USB-native connectivity simplifies integration into existing lab networks, while dual TTL and relay outputs enable synchronization with autosamplers, fraction collectors, or external detectors.
Applications
- Environmental monitoring: Quantification of fluoride, chloride, nitrate, sulfate, phosphate, and perchlorate in surface, ground, and drinking water per EPA Methods 300.0 and 300.1.
- Pharmaceutical quality control: Testing for residual counterions (e.g., sodium, potassium, chloride) in active pharmaceutical ingredients (APIs) and final drug products per ICH Q5C guidelines.
- Food and beverage safety: Detection of preservatives (benzoate, sorbate), adulterants (melamine), and nutrient ions (iodide, nitrite) in dairy, infant formula, and processed foods.
- Industrial process control: Monitoring of anionic impurities in semiconductor-grade ultrapure water and electroplating baths.
- Academic and method development labs: Platform for developing novel IC methods involving hydroxide elution gradients, large-volume injection, or hyphenated techniques (e.g., IC-ICP-MS).
FAQ
Is this ICS-2000 unit fully tested and calibrated prior to shipment?
Yes. Each unit undergoes functional verification at SpectraLab Scientific—including pump performance validation, conductivity detector linearity assessment, column oven temperature profiling, and baseline noise evaluation—using NIST-traceable standards.
Does the 6-month warranty cover parts and labor?
Yes. The warranty includes all components subject to normal wear and tear, excluding consumables (columns, guard columns, suppressors, filters). On-site technical support is available within North America and Europe; remote diagnostics and firmware updates are provided globally.
Can this system be upgraded to support newer Chromeleon versions or add modules like ASRS?
Yes. Hardware compatibility with Chromeleon v7.3+ is confirmed. Optional upgrades—including ASRS 300 suppressor, EGC III EG cartridges, or RFIC™ auto-sampler integration—are available upon request and subject to physical interface verification.
Are original manuals, certificates of conformance, and calibration records included?
Yes. A complete digital package—including scanned operator manuals, factory calibration reports, and a Certificate of Functional Verification—is delivered with each instrument.
What is the typical lead time for delivery and installation support?
Units are stocked and ready for immediate shipment. Standard delivery is 3–5 business days within the US/EU. Installation assistance—including basic setup, leak testing, and first-run method validation—is offered remotely or on-site by certified field application specialists.
