Iowa State University Ionwave #RFQ-1001526

Turnkey in-situ DEMS/EC-MS system for Iowa State University research

Iowa State University is seeking a turnkey electrochemical mass spectrometry system for research on NO electrooxidation and related reactions. - Buyer: Iowa State University of Science and Technology (ISU), Ames, Iowa. No sub-agency or purchasing office is identified. - Procurement: One complete in-situ Differential Electrochemical Mass Spectrometry (DEMS/EC-MS) system for real-time identification and quantitative analysis of gaseous and volatile electrochemical reaction products, supporting DARPA PECAN NO electrooxidation and related electrocatalysis research. - OEMs and vendors: No manufacturer, OEM, or vendor is named; suppliers may propose a system that meets the requirements. - System quantity: One turnkey system, including its required components, accessories, freight, installation, and training. No part numbers are specified. - Key equipment and capabilities: - Quadrupole mass spectrometer with a mass range of at least 1–100 amu, electron-impact ionization, electron multiplier and Faraday detectors, full-scan and selected-ion monitoring, and quantitative analysis software. - Integrated high-vacuum system with turbomolecular and dry backing pumps, gauges, and differential pumping. - Membrane-inlet/differential-sampling interface with a low-dead-volume transfer path, condensable-species management, valves and connections, and compatibility with aqueous experiments. - Adjustable probe-type DEMS cell with micrometer positioning and optical or camera-assisted monitoring, plus a classical DEMS cell with approximately one-second-or-faster response, membrane consumables, and operating accessories. - Operando electrochemical infrared interface with cells, electrodes, mounting hardware, and optical components, and a gas-diffusion-electrode cell for continuous gas-feed, high-current-density operation and product detection. - Notable preferences: Modular or upgradeable configuration, interchangeable cells or inlets, compact footprint, manageable routine maintenance, and compatibility with common FTIR spectrometers. - Supplier response requirements: Provide itemized pricing and technical data sheets for each component; include freight, installation, and training; describe technical support, warranty, delivery lead time, and references. - Warranty and optional service: Minimum 12-month warranty from equipment acceptance. Suppliers may separately quote preventive maintenance or service for 12 months beyond the standard warranty.
