Description

The Government intends to acquire a commercial item using FAR Part 12 and the Simplified Acquisition Procedures set forth in FAR Part 13. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation, which is issued as a Request for Quotation (RFQ); quotes are being requested and a written solicitation will not be issued. Offerors are required to use the On-Line RFQ system to submit their quote. The On-line RFQ system is linked above or it may be accessed at http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=C&pin= . The information required by FAR Subpart 12.6 is included in the on-line RFQ. NASA/JSC plans to acquire analytical services to measure and report water vapor in a product gas stream as part of a 5-day measurement campaign. The measurements will be made at NASA Marshall Space Flight Center (MSFC), Huntsville, AL, in March or April of 2001. The mechanical interface to the product gas stream will be a standard fitting; the measurement will require active sampling. The pressure of the gas stream will be between 2 psia and 10 psia. The rate of sampling should not exceed 50 scc/min (product gas flow is limited at some parts of the desorption cycle); a water vapor measurement should be reported every 5 minutes. The expected value of the water vapor is between 10 ppm and 50 ppb, and the measurement should have an accuracy of +/- 30% or better. The Space Station Carbon Dioxide Removal Assembly (CDRA) uses a series of adsorption beds to remove carbon dioxide from cabin air and vent the carbon dioxide to space vacuum. Researchers at NASA-Johnson Space Center are investigating approaches to recover the carbon dioxide and extract oxygen from the carbon dioxide. One of the key development issues related to carbon dioxide relates to the amount of trace water vapor found in the carbon dioxide product stream. Presently, the CDRA adsorption bed is configured to be heated and vented to space. The product gas stream is estimated to be greater than 95% carbon dioxide, contain less than 2% nitrogen, contain less than 1% oxygen, and contain somewhere between 10ppm and 50ppb water vapor. To properly design the carbon dioxide recovery hardware, it is important to know the water vapor content of the product gas stream. The concentration will vary as the bed is heated. The NASA Johnson Space Center plans to purchase commercially available analytical services to make trace water vapor measurements of the gas product stream coming from the CRDA located at MSFC. NASA JSC is soliciting quotations for this measurement and a report of the data. Questions regarding this acquisition must be submitted in writing (e-mail is preferred) no later than February 26, 2001. Prospective quoters shall notify this office of their intent to submit a quotation. It is the quoter's responsibility to monitor this site for the release of amendments (if any). Potential quoters will be responsible for downloading their own copy of this notice, the on-line RFQ and amendments (if any). An ombudsman has been appointed -- See NASA Specific Note "B".
