Implication of the Statistical Review of the Side By-Side Comparison of DWPF's ICPS
The Statistical Consulting Section (SCS) of the Savannah River National Laboratory received data from a series of side-by-side comparisons of two Inductively Coupled Plasma-Atomic Emission Spectrometers (ICPs) conducted by the Defense Waste Processing Facility Laboratory of Waste Laboratory Services. These two ICPs are designated as M-14, the current production ICP, and M-13, the new ICP being evaluated. The data received by SCS were outlined in the test plan [1] describing the series of tests, which involved three sample preparation methods, denoted as: ''cold chem,'' fusion, and mixed acid. A cold chemical (cold chem) preparation is used for samples of the Sludge Receipt and Adjustment Tank, SRAT, product. Fusion and mixed acid dissolutions are used to prepare samples of the Slurry Mix Evaporator, SME. For each of these three dissolution methods, several types of samples were prepared and measured (for chemical composition) by both ICPs. The samples included process samples (SRAT product for cold chem and SME product for fusion and mixed acid), blanks, check standards, and samples of the Analytical Reference Glass One, ARG-1. Groups of these samples were measured under 6 different calibrations of each of the two ICPs. The measurements of the process and ARG-1 samples were provided by element (16 elements in all) as weight percent concentrations. For these samples the elemental concentrations were converted to their corresponding oxide concentrations by using the appropriate gravimetric factors. In addition to these measurements, data associated with the determinations of the limit of detection, LOD, and limit of quantification, LOQ, for each element of interest for each ICP were provided to SCS.
