General description: | This Standard Reference Material (SRM) is intended for use in the evaluation of equipment, and the validation of methodology used to measure electrophoretic mobility. A unit of SRM 1980 consists of a single 60 cm3 polyethylene bottle containing 40 cm3 of suspension, which is to be diluted prior to analysis. The suspension consists of 500 mg/L goethite (a-FeOOH) suspension saturated with 100 μmol/g phosphate in a 5 × 10–2 mol/L sodium perchlorate electrolyte solution at a pH of 2.5. The goethite powder consists of acicular particles with an average dimension of 60 nm × 20 nm as determined from electron microscopy. For more information, please refer to the COA and SDS.
