NO FORMAL SOLICITATION IS BEING REQUESTED UNDER THIS NOTICE. This Sources Sought Notice is for market research purposes to identify interested firms for the potential requirement detailed below. The North American Industry Classification System (NAICS) code is 334516 (Analytical Laboratory Instrument Manufacturing) and the size standard is 1,000 employees. The Government will review the information requested in this announcement to determine the type of set-aside (if any) for this requirement, should it come to fruition. Note: The Buy American Act (41 U.S.C. 8301-05) is the primary federal procurement law providing a preference for domestic goods and manufactured products. As such, the USGS is seeking information on sources that can supply the described instrument either mined, produced or manufactured in the U.S. in sufficient and reasonably available commercial quantities of satisfactory quality. Introduction: The U.S. Geological Survey (USGS), National Water Quality Laboratory (NWQL), Denver, CO has a requirement to purchase of three block digestors, all required software, and warranty. The digestors shall be controlled for unattended, automated sample digestion of measured parameters by vendor-supplied software operated vendor supplied control panel. Background: Block digestors are currently used at the National Water Quality Laboratory (NWQL) to digest samples for Total Kjeldahl Nitrogen and Total Phosphorus in a wide range of water samples. The NWQL produces approximately 30,000 results for these two analytes annually. The purchase of three more digestors will be used to increase the throughput of analysis in the laboratory and will allow the NWQL to continue to provide high quality nutrient data in a timely manner to meet customer needs.
