Purchase IRGASON Gas Analyzer

This document is a Request for Quotation (RFQ) issued by USDA ARS Acquisition and Property D for an IRGASON eddy covariance sensor with datalogger and accessories. The RFQ, numbered 1232SA25Q0790, was issued on 09/09/2025, with a quotation due date of 09/15/2025 at 16:00 CT. The required delivery is by 06/30/2026 to the University of Missouri in Columbia, MO. The performance period for the supplies/services is from 09/19/2025 to 06/30/2026. This RFQ is not a small business set-aside and explicitly states that it is a request for information only, and submitted quotations are not considered offers. The government is not committed to paying any costs incurred during the preparation or submission of the quotation.

The Statement of Work (SOW) outlines the requirement for IRGASON integrated gas analyzers and sonic anemometers to complete eddy covariance systems. These systems will measure nitrous oxide fluxes in two study fields within the Central Mississippi River Basin to evaluate fertilizer management practices. The project, titled "Linkages Between Crop Production Management and Sustainability in the Central Mississippi River Basin," aims to improve understanding of nitrogen exchange between land and atmosphere. The contractor must supply specific Campbell Scientific IRGASON systems, including the IRGASON-6NA-BB-NC option, a CR6 datalogger, power and communication cables, a stabilizer brace kit, and a power converter. These components are essential for consistency with existing instrumentation and for accurate, continuous measurements of wind speed, direction, and H2O/CO2 concentrations at 20 Hz. Delivery is required within 90 days of the order. The document lists the specific items needed, emphasizing Campbell Scientific as the sole-source manufacturer for key components due to their unique capabilities and compatibility with existing equipment.
