PROBLEM TO BE SOLVED : To provide a sample preforming method capable of improving analysis accuracy in component quantification by a fluorescent x-ray analysis method, and to provide a component quantification method using the preforming method.
SOLUTION : In the sample preforming method to be used for the fluorescent x-ray analysis method after pressurization and principal forming, metal or alloy powder with 30 μm or less of average grain size D50 is filled in a mold and formed and the whole surface of a compact 5 to be irradiated with x-rays is pressurized by setting a pushing rate to 10 to 40%. When pressurizing the whole surface of the compact 5 to be irradiated with x-rays by setting the pushing rate to 10 to 40%, it is preferable to use a punch 4 for pressurizing the whole surface of the face irradiated with x-rays in the compact 5 and a guide 3 for guiding the punch 4, and it is also preferable to use oxide powder of rare earth-iron-boron group alloy as the metal or alloy powder.
