47 Analytical Laboratory suring ranges 5005000 m. Maximum sample length of 50 mm and diameter of 12 mm I resolution 0.125 nm1.25 nm. Equipped with several atmospheres inert oxidizing reducing static and dynamic. Netzsch STA409 thermogravimetric analysis TGA Temperature ranges from RT to 1600 C. Heating rate ranges from 0.001 to 50 Kmin. weighing range 35000 mg TG resolution over entire weighing range is 0.1 g DSC reso- lution 1 W. Equipped with several atmospheres inert oxidizing reducing static and dynamic. Automatic sample changer for up to 20 samples. All Netzch thermal property analysis instruments are located within the Fresh Fuels glove box to contain transuranic materials and irradiated non-fuel materials. Inductively coupled plasma-mass spectroscopy ICP-MS The Analytical Laboratory has two inductively coupled plasma mass spectrometers ICP- MS. The VG PQ3 instrument is enclosed in a one fourth glovebox while the ELAN DRC II instrument makes use of a radiological hood. Both containment devices the glovebox and hood are used to provide containment while performing analyses on solu- tions containing radioactive material. In both cases the plasma and sample introduction components are enclosed in the containment while pumps and electronics are outside of containment. The ICP-MS instruments are used to provide elemental and isotopic information on a fast time scale. The unit mass resolution instruments resolution is about 400 allows the de- termination of a wide variety of analytes relatively quickly. The instruments are most often used in the peak jumping mode which requires about 1-3 seconds per analyte chosen. A typical analysis will take approximately five minutes of instrument time for a wide variety of analytes. The instrument is capable of determining major components in fuels to fis- sion products. Typically most fission products from Rb-85 through Sm-154 are measure- able depending on the materials of construction and the irradiation history. The analytical figures of merit of the ICP-MS are quite good considering the quadrupole mass filter. Most analyses have a two sigma error of plusminus 3-5. The error determi- nation determined by the Guide to Uncertainty Measurement GUM is dominated by
