    Attachment_A_-_Questions_and_Answers-140G0225Q0052_0001.pdf
    The RFQ 140G0225Q0052 outlines the USGS's requirement for laboratory analytical services focusing on Lead (Pb) isotope ratio measurements in soil samples for the Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado. Two key questions were posed regarding the technical specifications. The first clarified that while a proposal suggested using multicollector ICP-MS, the USGS mandates the use of high resolution inductively coupled plasma mass spectrometry (HR-ICP-MS) to ensure comparability with specific methodologies referenced in the performance work statement. The second question sought information about sample processing, confirming that samples will be submitted in pulverized form, adhering to the specified preparation protocols. Additionally, the USGS's contracting officer emphasized that potential vendors should note this is a Request for Quote rather than a Request for Proposal. This document serves to clarify technical requirements and processing methods for vendors interested in submitting quotes.
