E-MAIL: Sharon L. Connolly, sconnolly@mail.arc.nasa.gov. NASA Ames Research Center plans to issue a Request for Quotation (RFQ) for two (2) each of Charge Distribution Analysis (CDA) instruments, Model CDA-01, P/N 314-0001. This procurement is being conducted under the Simplified Acquisition Procedure (SAP). NASA/ARC intends to purchase CDA-01 instruments from Phytron Instruments, Inc. 650 Saratoga Avenue, San Jose, CA 95129 on a sole source basis in accordance with 10 U.S.C. 2304(c)(1). The CDA-01 instrument characterizes the bulk polarization and surface charging of insulators and catalysts. The instrument is also capable of performing non-contact polarization measurements in a dc electric field gradient near the limit of 0 Hz and of separating and distinguishing data relative to the bulk polarization, surface charge and mass loss. The CDA-01 instrument offers a controlled temperature environment from 25 -- 700 degrees C and a gas atmosphere of 1 bar with the capability of mixing four gases through a mass flow controller. Partial pressures simulating low pressure planetary environments require the ability to control gas flow to within 0.1 mL/min. The CDA force sensor can measure forces with a resolution of one nanonewton (10xE-9 N) and a time response of 1 second. Samples will vary in size (5-7 mm dia x 2-3 mm thick) and weight (1-2 g). The CDA-01 instrument is compatible with an existing Apple Power Macintosh G3 computer running LabView virtual instrumentation software. Phytron Instruments is the supplier and intellectual property holder for CDA (U.S. Patent #4.884.031). The Government intends to acquire a commercial item using FAR Part 12. Interested firms have 15 days from the publication of this synopsis to submit in writing to the identified point of contact, their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after the 15 days or without the required information will be considered nonresponsive to thesynopsis and will not be considered. A determination by the Government to not compete this proposed effort on a full and open competitive basis, based upon responses to this notice is solely within the discretion of the Government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
