Sample Weight: 12.00 g


Method 26 Elements and Reporting Limits
Element Concentration (low) Concentration (high)
Ba, Barium 10 ppm 4000 ppm
Nb, Niobium 2 ppm 4000 ppm
Rb, Rubidium 2 ppm 4000 ppm
Sr, Strontium 2 ppm 4000 ppm
Y, Yttrium 2 ppm 4000 ppm
Zr, Zirconium 3 ppm 4000 ppm

Analytical Performance

Data will be deemed acceptable if recovery of each element is ±5% at five times the Lower Limit of Determination (LOD) and the calculated Relative Standard Deviation (RSD) of duplicate samples is no greater than 5%.
