Mettler Toledo and Thermo Fisher Scientific Titration-IC system

Mettler Toledo and Thermo Fisher Scientific have combined their expertise to provide multiparameter water testing. The Titration-IC (ion chromatography) system offers complete automation for testing properties and ions in drinking, ground, surface and waste water. The system minimises operator time and simplifies sample analyses.

The combined system improves efficiency by combining the determination of up to 20 different parameters - including conductivity, pH value and alkalinity - from a single sample into a completely automated workflow. The intelligent conditional capability of the titrator chooses the correct sample loop for anion analysis based on the conductivity of the sample.

The IC instruments provide analysis for common anions (F^-, Cl^-, NO₂^-, etc) and cations (Na+, NH₄⁺, Mg²⁺, etc). By combining the IC and titration results, the system can also provide results for total hardness, ion balance and carbonate hardness. All analyses on a single sample are completed in 20 min with only seconds of operator interaction.

After sample testing the system is automatically cleaned and rinsed, eliminating any chance of sample carryover. Due to the PowerShower rinse technology on the sample changer and mechanical cleaning of the IC lines by air then deionised water, cross-contamination is avoided.

The Mettler Toledo Liquid Handler device automates complex and tedious dilutions for IC standardisation. Not only does the automated dilution save time during the standardisation procedure, it also assures accuracy in dilutions for consistent and repeatable standardisations from one operator to the next.

The IC software integrates the control and results from both instruments. The laboratory operator needs only to interact with a single software system for sample identification and combined flexible reports with all sample results.
