Specifications include, but are not limited to: New Mexico Highlands University, located in Las Vegas, New Mexico is interested in purchasing an X-ray Single Crystal Diffractometer. This instrument is essential for maintaining state-of-the-art research in multiple academic Departments (Chemistry, Geology, etc.) at NMHU. The instrument will be used for teaching different classes (CHEM 5610 and CHEM 5190). The instrument will also be used to perform research and will be part of INBRE, PREM and DMREF current projects. 1. Efficient dual (Copper and Molybdenum) microfocus sealed tube source. 2. The X-ray source should have low energy consumption (100 watts or less per tube) and not require any coolers that reside outside the cabinet. 3. Beam sizes from the microfocused sealed tubes should have a FWHM of 130 µm or less. 4. At least three references from current users of the desired instrument. 5. Hybrid Photon Detector (HPC) technology is highly preferred. The detector should not require an external chiller or a beam stop. The scanning frequency for that detector must be at 100 Hz and show no measurable counts on detector images in regions masked by the beamstop.
