| The minimum quantity of the powder sample must be 3 gm. It is essential to provide the density of the powder as well as the density and viscosity of the medium in which the powder has to be homogeneously dispersed / suspended. The permissible spin fluids are ethylene glycol, sugar solution, glycerol, methanol and the mixtures of any of these with water besides water alone. |
