Abstract
Provided is a density gradient liquid production apparatus for producing a density gradient liquid in a measurement cell for a centrifugal sedimentation type particle diameter distribution measurement device and comprises a first solution preparation unit that prepares a first solution with a predetermined target concentration and a first density by mixing a plurality of first reference solutions each of whose concentrations of an agglomeration inhibiting component that inhibits agglomeration of particles differs, and a second solution preparation unit that prepares a second solution with the predetermined target concentration and a second density that is different from the first density by mixing a plurality of second reference solutions each of whose concentrations of the agglomeration inhibiting component differs, and a mixed solution preparation unit that creates a mixed solution with the target concentration by mixing the first solution and the second solution and supplies the created mixed solution to the measurement cell while varying a density of the mixed solution.
