The 948 Continuous IC Module enables fully automated generation of high-purity hydroxide eluents based on the electrolysis of water. This module is ideal for method development or routine analysis with switching methods. Our solution increases sustainability as it can be reused, less chemicals are needed, and waste is reduced.

Hydroxide eluents are used in a variety of applications from isocratic methods for the determination of major anions to convenient gradient methods for determining oxyhalides. More complex applications, such as analysis of haloacetic acids by hyphenation of ion chromatography with mass spectrometry, are also feasible and profit from high purity, accuracy, and ease-of-use.

Application Note: Water quality testing with EPA 300.1

The 941 Eluent Production Module integrates seamlessly with existing ion chromatographic setups of the 940 Professional IC Vario, 930 Compact IC Flex series, and other intelligent Metrohm IC devices, making ion chromatographic analysis more precise and efficient by automatic eluent production. This module eliminates manual dilution steps by producing eluents from a concentrate and ultrapure water in a software-controlled manner. Concentrates can be purchased from Sigma-Aldrich or made individually in the composition as needed for the analysis.

The 941 Eluent Production Module offers high flexibility by allowing the production of up to four different eluents, suiting for a wide range of anion and cation analysis. Continuous level monitoring of various liquid containers is integrated into the software and can perform appropriate actions to ensure uninterrupted operation and consistent performance. Continuous operation with minimal maintenance, delivering stable and contamination-free results, make it a cost-effective add-on for every Metrohm ion chromatograph.
