66 -- MOLECULAR MICROANALYSIS AND CHEMICAL MAPPING SYSTEM Sol DADA15-95-R-0029. Contact Ms. Ricki Taylor, 202/782-1284, Contracting Officer: Mr. Alfred Bariatti. It is the intention of Walter Reed Army Medical Center to negotiate on a sole source basis with Nicolet Instrument Corporation for an Advanced Modecular Microanalysis and Chemical Mapping System, which consists of a Fourier transform infrared (FT-IR) spectrometer, visible/infrared microscope, and Windows-based software combined with a scanning Infrared Microprobe package. It is believed that Nicolet Instrument Corporation is the sole source for this requirement under the authority of FAR 6.302-1 because of the following essential requirments: The microscope must be fitted with variable compensation Cassegrain objectives capable of compensating for samples/substrates of varying thicknesses; the microscope must be fitted with a rotatable nosepiece with positions for four objectives to include one attenuated total reflection (ATR) objective suitable for infrared spectroscopy, and one grazing-angle objective; the microscope must be fitted with a side-port reflectance accessory for analyzing specimens too large to fit on the conventional specimen stage; the microspectrometer system must have a dual aperture system to optimize data collection for specimens 50 microns or smaller; and the specimen stage must be at least 2'' x 3'' and designed to be used as a mapping stage that can be controlled manually and by the spectrometer's host computer (under computer control, the step size for the mapping stage must be at least 1 micrometer (1 micron) or better). Any competingfirm that is able to provide the above requirements must provide sufficient technical documentation to demonstrate that capability to the Government, and may request a copy of Solicitation Number DADA15-95-R-0029. No telephone requests will be accepted. (017)
