      Total 51 samples, tin not detected in any except the 10 Dugway Reverse Engineered
      samples.
      ABased on data in Table 1, excluding attack samples (shown by ICP-OES to contain
      tin) and negative SEM-EDX analyses of unsectioned samples, which reflect only
      the sample surface, not the entire sample.
      Bn.d. signifies not detected.
