66 -- AUTO SAMPLER COULOMETER SYSTEM DUE 080699 POC Marilyn Hutchison, Purchasing Agent, (303) 236-5900, x327 or FAX (303) 236-2710 E-MAIL: USGS, CR, Acquisitions & Federal Assistance, mhutchi@usgs.gov. Concerns having the ability to furnish the supplies described herein are requested to give written notification (including the telephone number for a point of contact) to the procuring office above within 45 calendar days from the date of this synopsis. The U.S. Geological Survey, Global Change and Climate History Team, requires reliable, precise, accurate, and rapid instrumentation for analyses of total, inorganic, and organic carbon in geological materials. An automated coulometer, which will increase the output of carbon analyses, is required to replace the manual coulometer currently in use. The coulometer shall have a wide, linear dynamic range of from 10 parts per million (0.001%) to 100% carbon. Total inorganic carbon and total organic carbon must be obtained by acidifying the sample to get rid of inorganic (carbonate) carbon, running another total carbon analysis which is taken as total organic carbon, and then calculate total inorganic carbon by difference. Based on information available at this time, and in accordance with 41 U.S.C. 253(c)(1), implemented by FAR 5.302-1, the Government considers the item specified as a sole source from UIC, Inc., Joliet, Illinois, and proposes to negotiate a contract with that firm on that basis. However, should additional sources be identified, they will be considered. Firms who feel that they can furnish the required supplies are invited to submit in writing an affirmative response to this announcement, and such other materials which correspond to the required items stated herein. This information will be evaluated and used to determine if competitive opportunities exist. Since no solicitation document exists, requests for such documents without accompanying information will be considered non-responsive to this request without further consideration. This notice may represent the Government's only official notice of this procurement. See Note 22. Posted 06/22/99 (W-SN345891). (0173)
