Dionex ICS-3000 Used Ion Chromatography System

Overview

The Dionex ICS-3000 is a high-performance, modular ion chromatography (IC) system originally engineered by Thermo Fisher Scientific (following its acquisition of Dionex in 2011) for advanced analytical laboratories requiring flexibility across ion analysis, bio-LC, and direct amino acid quantification. Built upon the foundational principles of suppressed conductivity detection and electrochemical detection, the ICS-3000 employs a dual-pump or single-pump configuration to support both isocratic and gradient elution — enabling precise control over mobile phase composition, flow rate (0.001–10.0 mL/min), and backpressure (up to 35 MPa / 5000 psi). Its architecture integrates RFIC™ (Reagent-Free Ion Chromatography) technology via the Electrolytic Eluent Generator (EG), eliminating manual eluent preparation and minimizing contamination risks associated with offline mixing. This results in superior baseline stability, enhanced sensitivity, and long-term reproducibility — critical for regulated environments including environmental monitoring, pharmaceutical QC, food safety testing, and academic research.

Key Features

• Modular dual-pump (DP) or single-pump (SP) configuration — field-upgradeable from SP to DP without hardware replacement
• Electrolytic Eluent Generator (EG) with single- or dual-channel capability; programmable high-voltage power supply and integrated vacuum degassing
• Detection versatility: Conductivity Detector (CD) with 0–15,000 µS range and Electrochemical Detector (ED) compatible with Ag, Pt, Au, and GC working electrodes
• Autosampler (AS) supporting four operational modes: concentrated injection, simultaneous injection, sequential injection, and sequential concentrated injection — ideal for trace anion/cation analysis and complex biological matrices
• Chemically inert fluidic path (PEEK, titanium, and ceramic components) optimized for biomolecule analysis, minimizing adsorption and metal leaching
• Integrated column compartment with temperature control (ambient to 60 °C) and dual valve positions for guard column, analytical column, and suppressor integration

Sample Compatibility & Compliance

The ICS-3000 accommodates a broad spectrum of sample types — including aqueous environmental extracts (e.g., drinking water, wastewater), food and beverage digests, pharmaceutical formulations, biological fluids (urine, serum), and industrial process streams. Its RFIC architecture ensures compliance with key regulatory frameworks: ASTM D4327 (anions in water), ISO 10304-1 (determination of dissolved anions), USP (conductivity of purified water), and EPA Methods 300.0, 300.1, and 317.0. When operated with audit-trail-enabled software (e.g., Chromeleon 7.x), the system supports 21 CFR Part 11 compliance through electronic signatures, secure user authentication, and immutable data archiving — making it suitable for GLP and GMP-regulated laboratories.

Software & Data Management

The system is fully compatible with Thermo Fisher Chromeleon Chromatography Data System (CDS) v7.2 or later. Chromeleon provides method development tools, real-time instrument control, automated calibration curve generation, peak integration with customizable baselines, and report templates compliant with ISO/IEC 17025 requirements. Raw data files (.cdf) are stored in a relational database with full metadata tagging (operator, timestamp, instrument state, sequence log). Audit trails record all user actions, parameter changes, and data modifications — ensuring traceability during internal audits or FDA inspections. Optional modules include eWorkflow templates for EPA-compliant reporting and integration with LIMS via ODBC or RESTful API.

Applications

• Environmental Analysis: Quantification of F⁻, Cl⁻, NO₂⁻, Br⁻, NO₃⁻, PO₄³⁻, SO₄²⁻, and cations (Li⁺, Na⁺, NH₄⁺, K⁺, Mg²⁺, Ca²⁺) in surface water, groundwater, and precipitation
• Food & Beverage Safety: Detection of preservatives (benzoate, sorbate), nitrate/nitrite in cured meats, sulfite in wines, and iodide in dairy products
• Pharmaceutical QC: Counter-ion profiling of APIs, residual acetate/formate in biologics, and chloride impurity testing per ICH Q2(R2)
• Biological Research: Direct amino acid analysis using AAA-Direct™ methodology — enabling quantitation of cysteine, tryptophan, methionine, phosphoserine, and other labile species without derivatization
• Energy & Power Generation: Monitoring of corrosion-promoting anions (Cl⁻, SO₄²⁻) and cations (Na⁺, K⁺) in boiler feedwater and steam condensate per ASTM D4582
