摘要： A method for screening a sample containing phenol, isopropylated phosphate (3:1), the method includes: steps 3 and 4 of acquiring a content of a compound group or a value corresponding to the content as a measured value for each of a plurality of compound groups among a compound group in which the total number of isopropyl groups that three phenyl groups of triphenyl phosphate have as substituents is 1, a compound group in which the total number is 2, and a compound group in which the total number is 3; and steps 5 and 6 of determining that the sample contains phenol, isopropylated phosphate (3:1) based on a result of comparing the measured value with a threshold determined previously for the compound group corresponding to the measured value.
