Abstract: PURPOSE: A method of fabricating a test sample for an X-ray fluorescence spectrometer is provided to shorten a test sample treating time and to prevent harmful gas from being created by performing a pre-treatment of the test sample without using storing acid. CONSTITUTION: After sampling a test sample to be analyzed, the test sample is pulverized by using a pulverizer. Then, 20 to 40 weight percent of polyvinyl alcohol, which is a bonding agent, is added to the test sample. After that, the test sample mixed with polyvinyl alcohol is compressed in a pallet shape by using a compressor. The pulverizing process for the test sample is carried out in such a manner that a size of the test sample is in a range about 1400 to 1600 meshes. The compressing process is carried out under compression load about 15 to 25 tons.
