About this opportunity
The US Geological Survey is conducting market research to identify qualified suppliers capable of providing components for Scanning Differential Optical Absorption Spectrometer (Scanning DOAS) instruments, with responses due May 12, 2026 by 1500 PST. This is a sources sought announcement for planning purposes only; no procurement commitment or contract award is anticipated from this notice.
The DOAS instruments support the Network for Observation of Volcanic and Atmospheric Change (NOVAC) network, which measures sulfur dioxide in volcanic gas plumes. Specific components solicited include a high-latitude plastic DOAS scanner with fused-silica tube designed for harsh environments and heated by stepper motor excess heat; a metal pole holder for mounting on steel pipe frames or masts; a six-meter motor cable with DB9 adapter and custom connectors; and a cylindrical quartz window with cylindrical lenses for collecting scattered UV radiation across wider angles to support wind speed measurements using dual beam capabilities. The scanner is delivered disassembled into mounting component, motor mounting component, and protective hood with four custom bolts and two fiber optics cable mounting holes.
NAICS code 334519 (Other Measuring and Controlling Device Manufacturing, small business size standard 600) and PSC 6630 (Chemical Analysis Instruments) apply. All responsible sources may submit product data sheets demonstrating ability to meet the technical specifications. Responses must be sent electronically to yangzhideng@usgs.gov and received by the deadline; hardcopy and web portal submissions will not be accepted. The Government will not reimburse costs incurred in responding.
