A method for preparing and analyzing a powder by means of instrumental analysis, wherein a solid body is produced that is formed from a two-component resin, wherein the solid body includes a plurality of powder granules which are separately and homogeneously present in the body and which are spaced apart from surrounding powder granules , wherein the powder granules that are arranged in the solid body are a statistically validatable powder representation of powder granules of a powder , the method including the steps: - introducing the powder granules of the statistically validatable powder representation into a liquid precursor stage of the solid body ; - separating and spacing the powder granules of the statistically validatable powder representation in relation to the surrounding powder granules of the statistically validatable powder representation and distributing them homogeneously in the precursor stage through the action of ultrasound and mixing means on the powder granules introduced into the precursor stage; - fixing the position of the separated powder granules of the statistically validatable powder representation through the transition of the precursor stage of the solid body into a solid body or the conversion of the precursor stage into a solid body , the precursor stage of the solid body including the powder granules of the statistically validatable powder representation which have been separated and spaced apart in relation to other powder granules of the statistically validatable powder representation and which are distributed homogeneously in the precursor stage , by adding a second component of the two-component resin to the precursor stage , wherein the distribution of the plurality of powder granules in the solid body is so homogeneous that the solid body has a uniform powder granule density, in particular over the entire solid body ; - representing (CT, 30) the solid body graphically, in particular via computed tomography; - determining and outputting at least one characteristic value of the statistically validatable powder representation of powder granules of the powder , by evaluating the at least one graphical, in particular computed-tomographic, representation (CT, 30) of the solid body . - introducing the powder granules of the statistically validatable powder representation into a liquid precursor stage of the solid body ; - separating and spacing the powder granules of the statistically validatable powder representation in relation to the surrounding powder granules of the statistically validatable powder representation and distributing them homogeneously in the precursor stage through the action of ultrasound and mixing means on the powder granules introduced into the precursor stage; - fixing the position of the separated powder granules of the statistically validatable powder representation through the transition of the precursor stage of the solid body into a solid body or the conversion of the precursor stage into a solid body , the precursor stage of the solid body including the powder granules of the statistically validatable powder representation which have been separated and spaced apart in relation to other powder granules of the statistically validatable powder representation and which are distributed homogeneously in the precursor stage , by adding a second component of the two-component resin to the precursor stage , wherein the distribution of the plurality of powder granules in the solid body is so homogeneous that the solid body has a uniform powder granule density, in particular over the entire solid body ; - representing (CT, 30) the solid body graphically, in particular via computed tomography; - determining and outputting at least one characteristic value of the statistically validatable powder representation of powder granules of the powder , by evaluating the at least one graphical, in particular computed-tomographic, representation (CT, 30) of the solid body . <EOS>
