LSD test for the five independent determinations, ordered as follows: (1) from slope and scaling masses; (2) digestion method A (HNO3); (3) digestion method B (HNO3 + HCl); (4) digestion method C (HNO3 + H2O2); and (5) certified/reference values; N means nonincluded; low case letters a, b, c, and d are classes ordered from lower to upper values; N.Q.: nonquantified; <MDL: below method detection limit.
Certified/reference values and obtained from slope and scaling masses are shown in Table 4(a).
