Atomic Absorption Procedures
Atomic Absorption Standard Dilutions & CalculationsNa2SO4 Dilution Standards 12mL 1 ppm Na2SO4 requires: (20ppm Na2SO4)V1 = (1ppm Na2SO4)(12mL) V1 = 0.6mL 12mL 2 ppm Na2SO4 requires: (20ppm Na2SO4)V1 = (2ppm Na2SO4)(12mL) V1 = 1.2mL 12mL 5 ppm Na2SO4 requires: (20ppm Na2SO4)V1 = (5ppm Na2SO4)(12mL) V1 = 3mL 12mL 10 ppm Na2SO4 requires: (20ppm Na2SO4)V1 = (10ppm Na2SO4)(12mL) V1 = 6mL 12mL 15 ppm Na2SO4 requires: (20ppm Na2SO4)V1 = (15ppm Na2SO4)(12mL) V1 = 9mL
12mL 1 ppm CuSO4 requires: (20ppm CuSO4)V1 = (1ppm CuSO4)(12mL) V1 = 0.6mL 12mL 2 ppm CuSO4 requires: (20ppm CuSO4)V1 = (2ppm CuSO4)(12mL) V1 = 1.2mL 12mL 5 ppm CuSO4 requires: (20ppm CuSO4)V1 = (5ppm CuSO4)(12mL) V1 = 3mL 12mL 10 ppm CuSO4 requires: (20ppm CuSO4)V1 = (10ppm CuSO4)(12mL) V1 = 6mL 12mL 15 ppm CuSO4 requires: (20ppm CuSO4)V1 = (15ppm CuSO4)(12mL) V1 = 9mL Notes
CuSO4 stock solution = 13.2 ppm Na2SO4 solution = 9.61 ppm
