About this opportunity
The U.S. Geological Survey Office of Acquisitions and Grants intends to solicit mineralogical analysis services for geologic samples under a total small business set-aside, with a sources sought notice due September 15, 2026.
The procurement covers two tasks: quantitative cation exchange capacity (CEC) and X-ray diffraction (XRD) analysis of 150 samples using full pattern fitting techniques, with CEC values reported at 0.1 meq/100g precision and results delivered in Excel spreadsheet format with raw xy data files; and specialized clay mineralogy analysis on 30 samples to identify specific clay types within the clay size fraction. The sources sought notice is market research only and is not a formal solicitation, RFP, RFQ, or IFB; submission is voluntary and respondents bear all associated costs. The Central Energy Resources Science Center is the requesting component.
NAICS 541380 (Testing Laboratories and Services) and PSC B599 (Special Studies/Analysis—Other) apply.
