Solution for routine and comprehensive water analysis

Significance of the topic

Industrial operations depend on reliable, high-purity water to prevent corrosion, scaling and ensure process safety. Global water scarcity and regulatory demands drive the need for comprehensive monitoring and reuse strategies.

Study objectives and overview

This work reviews an integrated solution combining fully automated discrete analyzers with ion chromatography for end-to-end water quality analysis. It aims to streamline workflows, increase throughput and consolidate multiple analytical methods into a single platform.

Methodology and instrumentation

Analytical methods integrate:

• Discrete photometric and electrochemical assays (pH, conductivity, colorimetric/enzymatic tests) using Thermo Scientific Gallery and Gallery Plus platforms with DECACELL cuvettes and ECM unit.
• Ion chromatography with Thermo Scientific Dionex systems (Aquion, ICS-6000, ICS-4000, Integrion) featuring reagent-free eluent generation, high-pressure operation, suppressors and concentrator columns.
• Data handling through Chromeleon CDS and automation modules (autosamplers, consumable tracking).

Main results and discussion

Systems demonstrated:

• High-throughput discrete analysis up to 350 tests/hour with parallel pH and conductivity measurement.
• Ultra-trace ion detection (ppt) and broad analyte coverage (anions, cations, amines, corrosion inhibitors, indicators).
• Reduced reagent consumption and waste generation through low-volume cuvettes and on-demand eluent generation.
• Seamless integration of regulatory methods (EPA, ISO) and real-time process monitoring.

Benefits and practical applications

Implementation provides:

• Consolidation of wet chemistry and chromatography methods into one workflow.
• Improved equipment protection, optimized chemical dosing and reduced operating costs.
• Enhanced lab productivity and data reliability with walkaway automation and LIMS connectivity.
• Compliance with discharge regulations and support for water reuse programs.

Future trends and opportunities

Emerging directions include:

• Online and in-situ monitoring for predictive maintenance.
• AI-driven data analysis to optimize process control.
• Expansion of analyte panels via IC-MS and novel detector technologies.
• Green chemistry approaches to further minimize waste.

Conclusion

The Disc-IC solution offers a robust, automated platform that meets diverse industrial water analysis needs, delivering high throughput, broad analyte coverage, and significant cost and resource savings.
