66 -- ATOMIC ABSORPTION SPECTROPHOTOMETER GRAPHITE FURNACE SOL W5-40870-F4 due 091495. Contact Point, Larry D. LaRue, (706) 546-3165, Contracting Officer, Jeffrey L. Napier, (404) 347-2374X6836. It is the intent of the U.S. EPA to negotiate with Perkin Elmer for the acquisition of an Atomic Absorption Spectrophotometer Graphite (Transverse) Furnace with multi-analyte capability. This instrument should be able to perform EPA Method 200.9 and achieve detection limits for Sb. As Se. T1. below 1 uqL while performing simultaneous analyses. This instrument must have the following components: a suitable sample introduction system for liquid samples, a graphite furnace capable of the rapid heating necessary for stabilized temperature platform furnace operation, a background correction system that will resolve analyte signal from background on a fast transient basis (Zeeman effect background corrections is required), lamp power supplies for both hollow cathode lamps (HCLs) and electrodeless discharge lamps (EDLs), and optical system for isolating wavelengths of interest, a detector capable of processing more than one analyte signal at a time, a cooling unit to provide removal of excess heat from the furnace, a fume extraction system, when coupled with the laboratory hood, provides a safe removal of all vaporized sample matrix, analyte, and matrix modifier and a computer, printer and software for controlling the instrument and accessories.
