    摘要: Method for preparing a mixed powder sample by mixing two or more different powders comprising transferring a quantity of a first powder to a mixing vessel and transferring a quantity of a second powder to the mixing vessel to form a powder bed in the mixing vessel comprising the first and second powders. The quantities of the powders are selected so the mixed sample has a predetermined ratio of first powder to second powder. The powder bed is fluidized to mix the powders and produce a mixed sample. The mixed sample weighs about 5 grams or less. The invention also includes apparatus for preparing mixed powder samples by mixing two or more different powders.
