Inventors include Kikuchi, Yuta; and Matsuo, Yoji.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present disclosure provides a filter in which a metal organic structure is supported on a base material, wherein: the average value of the amount of an S element with respect to the total amount of a target element included in the filter, as measured by fluorescent X-ray analysis, is 8-30 mol%; the target element is an element other than O and C, said element having a peak intensity of 10 cps or greater in fluorescent X-ray analysis; the peak intensity (cps) of the S element at a plurality of locations of the filter and the peak intensity (cps) of a metal element M constituting the metal organic structure are each measured by fluorescent X-ray analysis; the peak intensities of the S element and the metal element M at each measurement point are plotted, with the peak intensity (cps) of the metal element M being on the horizontal axis and the peak intensity (cps) of the S element being on the vertical axis; and a determination coefficient R 2 of a linear one-dimensional approximation formula derived using the least-squares method is 0.70 or greater.
