66 -- GAS CHROMATOGRAPH-COMBUSTION-ISOTOPE RATIO MASS SPECTROMETER SYSTEMS SOL CS-I-98-015 DUE 072798 POC Clarence Abernathy, Contract Specialist, (317) 298-1180 Ext.1206 The purpose of this requirement is to procure two each identical Gas Chromatograph-Combustion-Isotope Ratio Mass Spectrometer Systems (GC-C-IRMS Systems), one each, for the Los Angeles and one each for the San Francisco, California U.S. Customs Service Laboratories. The GC-C-IRMS System shall consist of: GC-C-IRMS, Continuous Flow Elemental Analyzer (EA), Ion Trap Mass Spectrometer (MS), dual viscous flow inlet, and automated H20 equilibration for determination of country of origin of natural materials. The instruments are being purchased to expand our analytical capabilities by providing state-of-the-art technology. The GC-C-IRMS systems must be capable of the following measurements: (1) determination of the isotopic ratios of oxygen, hydrogen, carbon and nitrogen in an in-line manner as compounds elute from the gas chromatograph; (2) chemical identification of each compound eluted from the gas chromatograph; (3) determination of the isotopic ratios of oxygen, hydrogen, carbon, nitorgen and sulfure inbulk samples; (4) determination of the total elemental compositions of oxygen, hydrogen, carbon, nitrogen, and sulfur in bulk samples; (5) determination of the isotopic ratios of oxygen, hydrogen, carbon, nitrogen, and sulfur in individual gas samples; and (6) fully-automated determination of the isotopic ratios of oxygen and hydrogen in aqueous samples. The installed instrument system shall be new, commercially available, and in commercial production as of the closing date of the solicitation. A performance/technical specification will be provided with each solicitation. In order to be considered for award each vendor must be capable of meeting all requirements of the specification. Evaluation criteria is lists as follows: A. Minimum Technical Specification weight 45% B. Serviceability, Support, and Training weight 20% C. Past Performance weight 15% D. Cost weight 15% E. Warranty weight 5% It is anticipated that award will be made to the contractor who submits a proposal that provides the best overall valuein terms of each of the evaluation categories identified above. This is an unrestricted requirement. Required delivery date shall be 60 days from the date of contract award. The GC-C-IRMS Systems shall be delivered as follows: 1 each to U.S. Customs Service Laboratory Los Angeles, California, and 1 each to U.S. Customs Laboratory San Francisco, California. Proposal are due on July 27, 1998, at 4:00 p.m., Indianapolis, Indiana time. Proposals shall be submitted in two parts, technical and cost to: U.S. Customs Service, Field Procurement Services Group, Attention: Clarence Abernathy, 6026 Lakeside Blvd., Indianapolis, Indiana 46278.
