Thanks to Inline Dilution and the patented matographs from Metrohm. Dosino technology, the 941 Eluent Production Module can be used to produce whichever eluent is required User benefits: from the respective concentrate. • More reliability • Continuous availability and stable conditions The dilution of the eluent concentrates with ultrapure If a dilution factor of 20 is selected, then two liters of water to the desired concentration takes place autoconcentrated eluent are sufficient for operating the IC matically. Manual steps – always a potential source of system for an entire month without interruption. error – are no longer required. • Low maintenance costs • More flexibility The production of eluents from concentrates is highly The 941 Eluent Production Module is supplied ex affordable, as all that is required is the dilution of the works for the production of one eluent. However, it respective concentrate with ultrapure water. can be upgraded without difficulty with optional accessories to enable the production of up to four eluents, no matter whether it be for the analysis of anions or cations, including the monitoring of auxiliary solutions and waste canisters. 03 Benefits of Inline Eluent Preparation • Automated Inline Eluent Preparation ensures stable retention times, contamination­free working and reliable measurement results • Free selection of the eluent with respect to component and concentration • Simple installation and integration of new and existing applications • Continuous, maintenance­free operation up to one month • Eluent concentrates can be produced inexpensively on your own or purchased conveniently from dealers • Direct connection of an ultrapure water system for high­purity eluents possible • Up to four eluents, parallel with one module Modular system integration: 940 Professional IC Vario ONE/SeS/PP with IC Conductivity Detector, 942 Extension Module Vario LQH, and 941 Eluent Production Module 04 941 Eluent Production Module, 940 Professional IC Vario, and ELGA PURELAB flex 5 ultrapure water system Stable measurements – guaranteed The Metrohm ion chromatographs of the latest genera­ If required, the PURELAB flex system also provides ultration leave the choice to you: You can produce the eluent pure water through a dispensing unit without interrupconcentrates required by weighing in and diluting the tion of the automated supply to the 941 Eluent Pro duc desired salts yourself.

Inline Eluent Preparation – convenient, time-saving, safe, and traceable ion chromatography The more convenient option is automated Inline Eluent Preparation. In this case, the eluent concentrates are diluted inline. The ultrapure water required for this purpose can be provided in a 10­liter canister. Even more convenience and reliability is possible by integrating an optionally available PURELAB flex 5/6 ultrapure water system from ELGA LabWater. In this case the ultrapure water nee ded for eluent preparation too is provided inline to the system: at any time, unlimited, fresh and free of contamination. The ultrapure water system can be fed with Continuous injections of a 250 µg/L multi­anion standard solution over a time conventional tap water. period of 21 days reveal an unprecedented retention time stability ELGA PURELAB flex 5/6: compact ultrapure water system for any feeder water The PURELAB flex 5/6 ultrapure water system from ELGA 05 LabWater was developed in cooperation with Metrohm especially for the requirements of ion chromatography. The «direct feed» flex 5 and flex 6 versions of the PURELAB system have an integrated recirculation chamber that ensures a supply of ultrapure water to Metrohm ion chromatographs that is guaranteed to be fresh. • Compact and reliable ultrapure water system for any feeder water • System for 18.2 MΩ-cm Type I ultrapure water in continuous operation (24/7) • Integrated UV lamp prevents bacterial contamination • Flexible dosing, variable extraction from drops up to 2 L/min • Preparation cartridge and UV lamp with rapid and simple replacement IC flow chart with integrated ultrapure water system IC system with Inline Eluent Preparation for the trace analysis of anions following Inline Preconcentration and matrix elimination MagIC Net – the proven software for ion chromatography 06 The new 941 Eluent Production Module is controlled by The preparation of any eluent is programmed within the the proven MagIC Net software for ion chromatography. instrument parameters of the desired method.

Fill level monitoring for greater safety In addition to eluent preparation, the integrated fill level ensure that the system never runs dry and that samples monitoring module enables reliable monitoring of auxilare only processed when solutions for the upcoming iary solutions and the waste canister. Sensors in various tasks have already been prepared. Fill level sensors guarlengths are optionally. Thus, for example, it is possible to antee maximum reliability and safety.
