Ion chromatograph OMNIS IC

ICchemicallaboratory

Overview Metrohm ion chromatographs for routine laboratory use and advanced research: modular and compact systems covering standalone routine analysis as well as fully automated and hyphenated configurations.

Range and instrument types Metrohm provides solutions from cost-effective compact instruments to modular high-end systems and specialized Combustion Ion Chromatography (CIC) setups for samples not amenable to direct injection. Representative instrument families include 940 Professional IC Vario, 930 Compact IC Flex and Eco IC, plus dedicated automation modules and sample processors.

Product families

• 940 Professional IC Vario (modular, flexible configuration)
• 930 Compact IC Flex (single-channel routine IC)
• Eco IC (compact entry-level instrument)
• Hyphenated techniques (IC-MS, IC-ICP/MS and other couplings)
• Metrohm Inline Sample Preparation (automation and intelligent injection)
• Combustion Ion Chromatography (CIC) for pyrohydrolytic conversion
• Automation for IC (autosamplers, sample processors, sample centers)
• Detectors for IC (conductivity, UV/VIS, amperometric, MS coupling)
• Columns for IC (separation, guard, precolumns, trap columns and accessories)

Capabilities and features

• Broad application coverage: anions, cations, sugars, amino acids, organic acids, transition metals, carbohydrates and amines.
• Support for suppressed and unsuppressed conductivity, UV/VIS, amperometric detection and MS hyphenation.
• Modular, upgradeable architecture with extension modules, additional pumps, detectors and automation options.
• Multiple gradient strategies: high-pressure gradient (HPG), low-pressure gradient (LPG), Dose-in gradients and hydroxide gradients via eluent generation.
• Automated eluent production and continuous hydroxide eluent generation for unattended operation.
• Inline and automated sample preparation (Inline Ultrafiltration, Inline Dialysis, MiPT) to increase throughput and protect columns.
• CIC for analysis of adsorbable organic fluorine (AOF) / PFAS screening and organic-halogen conversion.
• Comprehensive column portfolio covering ion exchange, ion exclusion and ion-pair separation mechanisms.

Software and data handling

• MagIC Net control and data software for Metrohm IC systems.
• Drivers and support for third-party chromatography CDS (OpenLab CDS, Empower) and instrument coupling.
• Options for audit-trail capable setups and regulatory workflows (21 CFR Part 11 when configured accordingly).
• Data export and LIMS integration via standardized interfaces.

Hyphenation and advanced configurations

• IC-MS and IC-MS/MS coupling for trace-level analysis and speciation (validated methods for short-chain PFAS available).
• IC-ICP/MS solutions for element speciation.
• Combustion IC (CIC) for conversion of organically bound halogens and PFAS-related screening workflows.

Applications

• Environmental and water/wastewater analysis (compatibility with relevant EPA and ISO methods).
• Pharmaceutical testing: compendial assays, impurity analysis and USP-relevant methods.
• Food & beverage analysis: sulfites, AOX/AOF workflows, sugars and organic acids.
• Chemical and energy industry analytics.
• Research and academia: method development, hyphenation and advanced separations.

Support & documentation Metrohm supplies application notes, brochures, webinars and technical resources covering instrument setup, method applications, column selection, automation and maintenance.
