Abstract: The method for particle analysis includes a first magnetic susceptibility measurement step S4 of measuring a volume magnetic susceptibility of each of first particles p1; an encapsulation treatment step S5 of performing an encapsulation treatment so that the first particles p1 encapsulate an encapsulation target component pt smaller than the first particles p1; a second magnetic susceptibility measurement step S8 of measuring a volume magnetic susceptibility of each of second particles p2 as an analysis target that are the first particles p1 after the encapsulation treatment; and a step S9 of analyzing whether or not the encapsulation target component pt is encapsulated in the second particles p2 based on a result of measurement in the first magnetic susceptibility measurement step S4 and a result of measurement in the second magnetic susceptibility measurement step S8.
