Method Description

The sample is diluted with reagent grade water and acidic

diluent (0.2% HNO3) containing 0.2% Trition X-100 surfactant and

20 mg/L Mg (NO3)2 matrix modifier. Diluted samples are then mixed

and analyzed via graphite furnace atomic absorption. The

sample's raw intensity is compared to a blood matrix-matched

calibration curve (from 0 ng/mL to 5.0 ng/mL Mn spiked samples).

The resulting concentrations of Mn in the sample cups are

corrected for the dilution factor. (Unpublished Mayo method)
