A chromatographic analyzer is provided for facilitating curve fitting by means of the linear least-square method for a chromatogram that contains a plurality of overlapping peaks. A plurality of through holes are disposed on the holder, wherein at least one light blocking portion is disposed between the two adjacent through holes. A mean diameter of the precious metal is 5 nm or larger. Soybean seed, cells, plants, germplasm, breeding lines, varieties, and plant parts produced by these methods andor derived from soybean variety XB74F13 are further provided. A voltage having a frequency sufficiently higher than the operation frequency of a power line is generated by the high-frequency power supply and applied to the arrester, and change in electrical characteristics due to deterioration of zinc oxide elements is detected as change in current including capacitive current, and then it is determined whether the detected change is good or bad.
