PROBLEM TO BE SOLVED: To provide a simplified analyzer, dispensing with cut-out work or setting work for a filtering film that contains cerium phosphate for selectively capturing lead ions, and allowing the quantity of lead ions to be determined on site in a simple and rapid manner. SOLUTION: The simplified analyzer includes a through-hole 12 with its upstream-side opening 17, made wide-mouthed while letting a specimen liquid run therethrough from the upstream-side opening 17 to its downstream-side opening 18; a basic filtering material 20 provided in the middle of the through-hole 12; and a lead-ion capturing film 22, made by fixing fibrous cerium phosphate on the surface of the filtering material 20, by supplying slurry that contains the cerium phosphate to the upstream-side opening 17. The capturing film 22 is placed on the outside so that it is visible, in a directly visible way from the upstream-side opening 17 of the through-hole 12. COPYRIGHT: (C)2011,JPO&INPIT
