Thermo Fisher Dionex Inuvion Ion Chromatography System (Rental)

Overview

The Thermo Scientific™ Dionex™ Inuvion™ Ion Chromatography (IC) System is a modular, user-centric benchtop instrument engineered for high-reproducibility anion and cation analysis in regulated and research environments. Based on suppressed conductivity detection and eluent generation principles, the system employs a dual-pump gradient-capable fluidic architecture to deliver precise, low-drift separations across diverse sample matrices—including environmental water, pharmaceutical excipients, food extracts, and battery electrolytes. Its design philosophy centers on operational accessibility: all critical components—including the eluent reservoirs, suppressor, detector cell, and injection valve—are positioned within ergonomic reach, eliminating the need for step stools, extended tools, or panel disassembly during routine maintenance or method changes. The system operates under ISO/IEC 17025-aligned workflows and supports full traceability requirements for GLP and GMP-compliant laboratories.

Key Features

• Integrated eluent degassing and electrochemical suppression—standard configuration ensures baseline stability and reduced background conductivity drift.
• Thermostatted high-performance conductivity detector with temperature compensation (±0.01 °C control), minimizing thermal artifacts and enhancing inter-day reproducibility (RSD < 1.2% for chloride at 1 ppm).
• Dual-range digital conductivity output (0–18,000 μS full scale) with auto-ranging capability—enables simultaneous quantification of major and trace analytes in a single chromatographic run without manual gain adjustment.
• Entire fluid path constructed from inert, metal-free PEEK and PTFE materials—resists degradation from strong acids (e.g., HNO₃, H₂SO₄), bases (KOH, NaOH), and organic modifiers; eliminates metal leaching and column fouling risks.
• Electronically actuated Rheodyne PEEK six-port injection valve—delivers precise, repeatable 25–100 µL loop injections with < 0.2% RSD volume accuracy and minimal carryover (< 0.01%).
• Modular suppressor options: electrolytic (Dionex AERS 500/CERS 500) or chemical regeneration—enabling method flexibility for high-salt matrices or specialized applications such as lithium-ion battery catholyte analysis.
• RFIC™ (Reagent-Free IC) upgrade path—supports on-demand KOH/MSA/K₂CO₃ eluent generation, enabling linear, nonlinear, and multi-step gradients with sub-microliter precision and long-term eluent stability (> 4 weeks unattended).

Sample Compatibility & Compliance

The Dionex Inuvion IC System accommodates aqueous samples with total dissolved solids (TDS) up to 1000 ppm and suspended particulate content < 0.45 µm (pre-filtered). It supports EPA Methods 300.0, 300.1, and 314.0; ASTM D4327 and D6919; ISO 14911 and 10304-1; and USP <645>. All hardware and software modules comply with IEC 61000-6-3 (EMC) and UL 61010-1 safety standards. When configured with Thermo Scientific Chromeleon™ CDS v7.3 or later, the system meets FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, role-based access control, and immutable raw data archiving.

Software & Data Management

Chromeleon Chromatography Data System (CDS) is supplied with validated license and integrated instrument control. The software provides sequence-driven acquisition, real-time peak integration using adaptive baseline algorithms, customizable report templates (PDF, CSV, XML), and automated calibration curve generation with weighted least-squares regression. Audit trail logs record all user actions—including method edits, result overrides, and reprocessing events—with timestamps, operator IDs, and IP addresses. Data integrity is enforced via write-once-read-many (WORM) storage options and optional network-based backup to NAS or cloud repositories compliant with ISO 27001.

Applications

• Environmental monitoring: Quantification of F⁻, Cl⁻, NO₂⁻, Br⁻, NO₃⁻, PO₄³⁻, SO₄²⁻, and AsO₂⁻ in drinking water, wastewater, and soil leachates per EPA Method 300.1.
• Pharmaceutical quality control: Counterion profiling (Na⁺, K⁺, Ca²⁺, Mg²⁺) in APIs and excipients; residual acetate and citrate in biologics formulations.
• Food & beverage safety: Detection of preservatives (benzoate, sorbate), nitrate/nitrite in cured meats, and iodide in dairy products.
• Energy materials: Anionic impurity screening (Cl⁻, SO₄²⁻, F⁻) in LiPF₆-based electrolytes and cathode slurries for EV battery manufacturing.
• Chemical manufacturing: Trace halide analysis in caustic soda, hydrochloric acid, and hydrogen peroxide solutions.

FAQ

What rental terms are available for the Dionex Inuvion IC system?
Standard lease durations range from 1 month to 36 months, with options for short-term project deployment, rent-to-own conversion, and capital lease structures. Minimum term is 30 days; extensions require 15-day advance notice.
Is method validation support included in the rental package?
Yes—Thermo-certified application specialists provide remote or on-site IQ/OQ documentation assistance, system suitability testing guidance, and SOP template development aligned with ISO/IEC 17025 and USP <1058>.

Can the system be upgraded to RFIC functionality during the rental period?
Yes—RFIC module installation and software licensing can be added at any time; associated costs are prorated based on remaining lease duration and billed separately.

What maintenance and service coverage is provided?
All rentals include comprehensive preventive maintenance (PM) every 6 months, 24/7 remote diagnostics, and priority response for hardware failures under Thermo Fisher’s Platinum Service Agreement—covering parts, labor, and loaner instrument provisioning during repair.

Are consumables and columns included in the rental fee?
Standard consumables (eluent cartridges, suppressor cartridges, guard columns) are billed separately on a usage basis; analytical columns may be included in extended-term agreements upon request.
