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.

### Description
