PROBLEM TO BE SOLVED: To provide a regulation method for a liquid sample for fluorescent X-ray analysis allowing the fluorescent X-ray analysis by a spot method, even in arsenic or the like of a heavy metal of a positive ion vaporized easily when dried, and a fluoride ion of a negative ion. SOLUTION: Since a valency of the positive ion of the heavy metal is brought into a valency stable against a liquid absorbent 4 by oxidation reaction of the spotted heavy metal in a solution with nitric acid, the heavy metal is immobilized to prevent vaporization so as to allow the fluorescent X-ray analysis by the spot method for the heavy metal of the positive ion easily vaporized when dried.
