Method for determining atomic composition using four-color X-ray equipment

A method for determining an atomic composition using a four-color X-ray machine, comprising:

• inspecting atoms using the X-ray machine displaying a four-color image and classifying the atoms into a first group to a fourth group by indicating the first group comprising atoms having atomic numbers 1 to 10 in a first color, indicating a second group comprising atoms having atomic numbers 12 to 18 in a second color, indicating a third group comprising atoms having atomic numbers 20 to 40 in a third color, and indicating the fourth group comprising atoms having atomic numbers 42 or more in a fourth color on the periodic table, and
• when inspecting a material containing a molecular unit using the X-ray machine displaying the four-color image, displaying the color of the group comprising the atom having a greatest atomic number among the atoms contained in the material, and determining which group among the first group to the fourth group the atom having the greatest atomic number belongs,
• wherein if the material contains sodium (Na) having an atomic number 11, potassium (K) having an atomic number 19, or niobium (Nb) having an atomic number of 41 on the periodic table is inspected, the atom of sodium, potassium, or niobium does not affect the displaying the color.
