Metrohm 930 Compact IC Flex ion chromatography system

Importance of the Topic

The ability to perform reliable, high-throughput ion chromatography is essential for quality control and compliance in environmental, pharmaceutical, food, chemical and petrochemical laboratories. The 930 Compact IC Flex addresses this need by delivering a compact, robust and flexible platform that streamlines routine analysis of anions, cations and polar substances across a wide concentration range.

Objectives and Study Overview

This whitepaper introduces the Metrohm 930 Compact IC Flex system as an entry-level yet versatile workhorse for routine ion chromatography. It aims to highlight the instrument’s design philosophy, modular configuration options, inline sample preparation methods, automation capabilities and software-driven quality assurance features.

Methodology and Instrumentation

The 930 Compact IC Flex platform is built around:

• Modular high-pressure dual-piston pump (0.001–20 mL/min).
• Chemical suppressors (MSM, MSM-HC, MSM-LC) with STREAM eluent recycling and 10-year rotor warranty.
• Detectors: high-performance conductivity with DSP, UV/VIS and amperometric options.
• Intelligent injection valves supporting full-loop, internal-loop, MiPT (Metrohm intelligent Partial-Loop) and MiPuT (Pick-up) techniques for a 10 µg/L–100 mg/L dynamic range.
• Optional column oven (0–80 °C), eluent/sample degasser, eluent production module with gradient dosing, inline sample preparation (dilution, ultrafiltration, dialysis, matrix elimination).
• Automation via up to six autosampler types (858, 863, 889, 814, 815, 919) in 23 configurations, supporting 24/7 operation.
• MagIC Net software for method control, self-monitoring, automatic dilution and recalibration, and GLP/FDA-compliant data management.

Main Results and Discussion

Key performance features include:

• Detection limits in the low µg/L range and linear quantification up to g/L levels.
• Uninterrupted suppression cycles for at least two weeks using STREAM, reducing reagent consumption and waste.
• Automated error detection and messaging, with self-correcting routines such as check-standard verification and on-the-fly sample dilution.
• Space-saving footprint and easy access to all fluidic and electronic components.
• Flexible online configurator enabling over 90 component combinations tailored to application requirements.

Benefits and Practical Applications

The 930 Compact IC Flex delivers:

• High reliability and minimal maintenance efforts, lowering total cost of ownership.
• Enhanced laboratory efficiency through full automation and inline sample preparation.
• Compliance with GLP and FDA guidelines, ensuring data integrity for regulated environments.
• Adaptability across industries: drinking water, waste water, infusion solutions, biofuel quality, petrochemical feedstock and more.

Future Trends and Applications

Advancements likely to shape next-generation routine IC include:

• Expanded inline sample preparation techniques for complex matrices.
• Integration with laboratory information management systems and cloud-based analytics.
• Further miniaturization and green chemistry approaches, reducing solvent use and waste.
• Enhanced AI-driven diagnostics and predictive maintenance.

Conclusion

The 930 Compact IC Flex combines modular design, intelligent hardware and software automation to meet the demands of routine ion chromatography. Its flexibility, reliability and ease of use position it as an ideal instrument for contract laboratories, QC environments and research facilities seeking robust analytical performance with minimal hands-on effort.
