66 -- CUSTOM PHOTOACOUSTIC DETECTOR SOL RQ98-018 DUE 051598 POC Brenda Goodwin, 304/285-5882/Contracting Officer, Rex S. Wolfe, 304/285-5883 The National Institute for Occupational Safety and Health (NIOSH) in Morgantown, WV has a requirement to acquire a CUSTOM PHOTOACOUSTIC ACCESSORY designed and manufactured for the analysis of solids and liquids using Photoacoustic Fourier Transform Infrared Spectroscopy (PA-FTIR). Preliminary results using a commercially available photoacoustic accessory with silica on a 9mm filter indicate that the PA-FTIR method may be feasible for occupational sampling. The Government requires a photoacoustic accessory that can accommodate 37 mm filters (and 25 mm and/or 47mm if possible) at full beam width. (These filters are often non-uniformly loaded with the majority of the material being in the center of the filter.) The unit must be able to fit into the sample compartment of a Perkin Elmer Paragon 1000 FTIR or attach to the left side as an external component. It must be able to interface both electronically and optically with the Perkin Elmer Paragon 1000 FTIR to produce PA- FTIR spectra. The unit must have a desktop power supply, a cord set specific for country or operation, signal cable specific for FTIR, sample cups, and Allen wrenches (or the specified tools required for operation and maintenance). The unit also requires a liquid crystal for imaging infrared radiation beam position, carbon black standard, an operating manual, applications literature including any unpublished data on operation and performance of the custom attachment and a one year warranty. A storage case with appropriate insulation so that all parts may be contained in it for travel and storage must also be provided. Vendors capable of providing such a custom photoacoustic accessory are invited to submit appropriate documentation, literature, brochures and references to Brenda L. Goodwin, Reference: RQ98-018, DHHS, PHS, CDC, NIOSH, ALOSH, 1095 Willowdale Road, Morgantown, WV 26505. If no organizations respond and demonstrate their capabilities within 15 days after posting of this notice, the Government intends to negotiate on a sole source basis with MTEC Photoacoustics, Inc., 543 Forrest Glenn Street, Ames, IA 50014. This notice is issued for informational purposes. (0120)
