This firm fixed-price purchase order was awarded by the Department of Commerce's National Institute of Standards and Technology (NIST) to Kratos Analytical Inc., a wholly owned subsidiary of Shimadzu Corporation based in the United Kingdom. The $124,500.00 contract is for the repair and maintenance of a NIST-owned Kratos Axis Ultra DLD X-ray Photoelectron Spectrometer. The one-year award, with two one-year option periods, was made on a sole-source basis, as Kratos Analytical is the only authorized provider with the necessary technical data, parts, and expertise to service this proprietary system. There was no set-aside designation for this acquisition, which was conducted using commercial item procedures without a competitive solicitation.
