49 Analytical Laboratory Inductively Coupled Plasma Atomic Emission Spectroscopy ICP-AES The ICP-AES instrument attached to Hot Cell 6 utilizes a lead lined glovebox. The plasma and sample introduction equipment is located inside the glovebox. The atomic emission is transported to the spectrometer via a quartz window that is installed in the glovebox. The lead lining allows for the analyses of samples that have considerable gamma signature with minimal whole body exposure to the scientific staff. The ICP-AES is used to measure elemental concentrations of metallic elements from mid nanogram per milliliter ngmL or ppb up to species that are major components. Most species have detection limits in the low ngmL. Thermal ionization mass spectrometry TIMS The longest established and proven method for doing uranium and plutonium in PIE samples is the TIMS instrument. The TIMS instrument utilizes a magnetic sector mass fil- ter and seven faraday cups to simultaneously measure the ions generated from the thermal ionization of the sample. By utilizing isotope dilution spiking with a known amount of U-233 or Pu-244 a very accurate and precise measurement is achieved. The end result is a total assay of less than 1 percent RSD at 2 sigma for U and Pu. The precision of isotopic determinations for major components are better than 0.1 percent two sigma. Uranium and plutonium measurements on the TIMS have one of the highest QC regimens in the AL. Uranium and plutonium measurements are made with longstanding QC sam- ples which have control charts for both isotopic composition and totals. Waste form testing glove box The WFTG is used for contamination control during metallographic sample preparation of actinide bearing materials and associated samples and other analytical sample prepara- tion applications which include but are not limited to sectioning of materials. It is a single glove box system with a main operating floor and a floor level well on the west end of the box. The east end of the glove box is equipped with a transfer port with sealed doors three glove ports. The glove box has a one pass air atmosphere with pre-filters that are exhaust- ed through double high-efficiency particulate air HEPA filters. The glove box is equipped with multiple furnaces.
