66 -- MULTI-ANALYTE GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROPHOTOMETER SOL D600004M1 POC Lenora Hilliard, Contract Specialist, (919) 541-4392/Janice F. White, Contracting Officer, (919) 541-4392. The Environmental Protection Agency has a requirement for a simultaneous, multi-element graphite furnace atomic absorption system. The system must include a spectrometer, furnace component, background correction system, circulating cooler, intelligent autosampler, printer/plotter, personal computer controller, and software. Additionally, the system must meet the following specifications: (1) capable of rapid heating necessary for stabilized temperature gradient along the optical viewing axis of the sample atomization cell (2) a background correction system capable of correcting for broad-band and structured background signals at the exact analyte wavelength (throughout entire workable range) at a minimum of 1.5 absorbance units (3) ability to process more than one analyte signal at a time (4) adequate stability and low noise characteristics such that under compromise conditions required for multianalyte operation, detection limits ( 1 ug/L for antimony, arsenic, selenium, and tallium can be obtained, and (5) ability to introduce an alternate gas stream. The Government anticipates awarding a firm fixed price contract. The RFP is expected to be released on or about November 13, 1995. A copy of the source list will be provided at the time the solicitation is issued. Telephone and telefax requests will not be accepted. (0298)
