## Description

XRF and ICP-MS analyses of geological samples Notice of Intent This is a notice of intent to solicit from a single source. The U.S. Geological Survey (USGS), intends to award a purchase order to Washington State University, Peter Hooper GeoAnalytical Lab for major and trace element analyses of geological samples by an X-ray fluorescence (XRF) spectrometer and Inductively coupled plasma mass spectrometry (ICP-MS).

Award will be made in accordance with Federal Acquisition Regulation (FAR) 13.106-1(b) and the procedures at FAR Part 12 entitled, Acquisition of Commercial Items and FAR Part 13 entitled, Simplified Acquisition Procedures. Midwest Lake Management is, to the USGS’ knowledge, the only source who can provide the equipment with the required technical specifications. The USGS currently owns a Midwest system. Therefore, data comparability and consistency are critical for these analyses.

The purpose of this notice is to satisfy the requirements of FAR Subpart 5.101(a)(2) and FAR 5.2. This notice of intent is not a request for competitive quotes. However, all responsible parties may submit a quotation by the closing date of this announcement which shall be considered by the agency. No solicitation will be issued. A determination not to compete this action based upon responses received is in the sole discretion of the Government. The NAICS code for this action is 541380, Testing Laboratory.
