Holder for drying, method of manufacturing measurement sample, and measurement method

A method of manufacturing a measurement sample comprising:

• fixing filter paper to a holder for drying, wherein the holder includes
• a first member including a first tubular portion that protrudes like a tube, and an annular projecting portion extending around an outer peripheral surface of the first tubular portion, the annular projecting portion projecting radially outward from the outer peripheral surface of the first tubular portion, and
• an annular second member configured to fix the filter paper in a flat state under tension;
• impregnating the filter paper with a liquid containing an object;
• and
• drying the filter paper while the filter paper is held by the holder for drying, wherein
• the fixing of the filter paper includes fitting the annular second member over the filter paper so as to surround an outer side of the first tubular portion while the filter paper xtends across an end of the first tubular portion, and such that a portion of the filter paper is sandwiched between a lower end surface of the second member and an upper surface of the annular projecting portion.

• impregnating the filter paper with a liquid containing an object;
• drying the filter paper while the filter paper is held by the holder for drying;
• and
• conducting analysis by Fourier transform infrared spectroscopy by irradiating the filter paper with infrared rays while the filter paper is held by the holder for drying after the drying of the filter paper, wherein
• the fixing of the filter paper includes fitting the annular second member over the filter paper so as to surround an outer side of the first tubular portion while the filter paper extends across an end of the first tubular portion, and such that a portion of the filter paper is sandwiched between a lower end surface of the second member and an upper surface of the annular projecting portion.
