66 -- PASSIVE CAVITY AEROSOL SPECTROMETER PROBE SOL NRMGC300905053DT DUE 081799 POC Doris Turner, Purchasing Agent, 303-497-3872; FAX: 303- 497-3163 E-MAIL: NOAA; MASC Acquisition Management, Doris.P.Turner@noaa.gov. The National Oceanic and Atmospheric Administration (NOAA) requires a passive cavity aerosol spectrometer probe to be mounted on the outside of an aircraft designed to measure particle size spectra for aerosol particles from 0.1 to 3.0 microns in diameter. This instrument must fit in a standard Particle Measuring System (PMS) canister, roughly 7 inches in diameter and 31 inches long. It must weigh less than 50 pounds. Power requirements are 115 V ac 50-60 Hz 1A for operation with 28 V DC 10A for the heater. It must be able to measure particle concentrations in 15 size bins for aerosols from 0.1 to 3.0 microns in diameter. It must be specifically designed for airborn use, be very robust, mount on the outside of the aircraft, and require no additional plumbing arrangement (air inlets) than that which come standard with the probe. Interested sources proposing to supply the instrument specified must submit a written qualification statement clearly establishing capability to meet the above requirements within 15 days from the date of this synopsis. The qualification statements will be used to determine the need for competitive bids. In the absence of other qualified sources, it is the intent of the Government to negotiate a sole source contract under the authority of 41 U.S.C. 253(c)(1) with Particle Measuring System Inc., 5475 Airport Boulevard, Boulder, CO 80301 as this source is considered to be the only responsible source and no other items will satisfy agency requirements. This announcement is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00).
