65 -- LC-EC WORKSTATION CAPABLE OF ELECTROCHEMICAL DETECTION SOL 263-96-Q-0233 POC Christine Albin, Purchasing Agent, (301) 402-3355. The National Institutes of Health, NIH, intends to procure on a firm fixed price, sole source basis in accordance with FAR 6.302-1 as authorized by 41 U.S.C.253(c)(1) a LC-EC Workstation from Rainin Instrument Co., P.O. Box 4026 Mack Road, Woburn, MA 01888. This workstation shall be a system capable of electrochemical detection with the following imperative characteristics: (1) Ability to operate in DC, PULSE, and SCAN modes providing a capability for detection of analytes that may not be detectable by the ''typical'' DC mode. (2) Workstation integrated components combining oven and Faraday-shielded compartment, to accommodate flowcell, column, pulse damper, and injector. (3) Recorder output of 12 bits or better, and analog integrator output. (4) Programming ability to modify the integrator output (time programmable integrator output) during the processing of a sample. (5) Very wide dynamic range for the detector of 10 picoamps to 5 microamps or better, with a resultant ability to change sensitivity by a factor of 500,000 within a single run. (6) Configuration of flowcell to incorporate wall-jet design for very favorable signal to noise ratios. (7) Flowcell minimum volume of 10 nanoliters, +,- 1 nanoliter. (8) Character display for unified single screen status information. (9) Operable by computer control, via an RS-232 serial interface. (10) May act as a control station to operate other units. (11) Power input of 110-120/220-240 volts AC, 50/60 hertz. It is the Governments belief that these requirements can only be met by the Rainin Instrument Co. Inc. (Antec Analytical Technology). This is not a formal solicitation, however, concerns that respond to this notice shall furnish concise responses directed specifically to the requirements mentioned above. Sources demonstrating the capability to accomplish the above shall supply pertinent information in sufficient detail to demonstrate their ability to perform. Information furnished shall include enough material to conduct a proper evaluation. Respondents will not be notified of the evaluations results. Individuals should respond no later than 15 days after date of issuance. See Note 22 (0094)
