Holman, Contracting Officer, 601-634-2423 The USAE Waterways Experiment Station proposes to issue a sole source contract to Perkin-Elmer Corporation, Norwalk, CT for the purchase of a six element simultaneous graphite furnace atomic absorption spectrometer with Zeeman background correction. The instrument must have the capability to be configured to any six of the 20+ elements for which lamps are available. The flexibility of the Perkin-Elmer instrument is needed to analyze a wide selection of elements in matrices where Zeeman background correction is essential. Perkin-Elmer is the only known source that can provide this requirement. If no other sources are found the Government intends to award a contract to Perkin-Elmer Corporation pursuant to the authority of 10 USC 2304 (c) (1). See numbered Note 22. (0111)
