52 -- AUTOMATED PARTICULATE MATTER SAMPLERS SOL 00-EPCD-1 POC Matthew J. Growney PH (513)487-2029 FX (513) 487-2107 E-MAIL: Matthew J. Growney, Growney.Matthew@epa.gov. Under authority granted in FAR 6.302-1, the U.S. Environmental Protection Agency intends to seek a quotation on a SOLE SOURCE BASIS from Rupprecht & Patashnick Co., Inc. for three (3) model 6125 Automated Particulate Matter Samplers. These particulate matter samplers will be used to accurately investigate continuously regenerable trap (CRT) diesel particulate emissions without the need for manual filter handling. The Government's minimum requirements for these automated samplers are as follows: (1) Each sampler's capacity shall not be less than 10 isolated filters per cartridge change. The filter holders shall be of the single filter configuration, and shall be compatible with 47mm diameter Pallflex TX-40 filters. (2) The samplers shall be designed to provide at least 100 slpm leak-free flow across the entire sampling system at up to 150" H2O pressure drop across the system. (3) The samplers shall be designed to provide continuous filter face temperature + /- 3 degrees C and filter dP data + /- 0.5" H2O, and shall be designed to accumulate total standard volume flow +/- 1.5% of setpoint (20-100 slpm) across the filter during sampling. (4) The samplers shall be software controllable such that volume flow rate, sample start, sample stop, purge start, purge stop, leak-check, and filter change, can be synchronously triggered from a single remote host computer. (5) The samplers shall have a sample bypass feature such that the mass flow controller will have continuous flow prior to sampling. The samplers also have a purge feature such that the sample probe is purged with air when the sampler is not sampling. (6) The samplers shall provide a means to associate filter ID to the recorded temperature, pressure, elapsed time, and total flow data, and the samplers shall provide a means to electronically transfer this data to a host computer. The initial evaluation sampler will be required no later than ninety (90) days from the purchase order issue. Delivery of the remaining samplers shall occur no later than sixty (60) days after EPA and the contractor agree on any minor modifications to the originally delivered evaluation sampler. This procurement will be accomplished under FAR Part 13, Simplified Acquisition Procedures. Interested firms may identify their interest and capability to respond to the requirements. This notice of intent is not a request for competitive quotations. A determination by the Government not to compete this acquisition based upon responses to this notice is solely within the discretion of the Government. Sources wishing to be considered must submit documentation to the office identified above. Documentation must be submitted within 15 days of the date of publication of this notice. Submit your request in writing to Matthew J. Growney at the above address or by fax 513-487-2107. Telephone request will not be honored. Posted 06/15/00 (W-SN465006). (0167)
