    • PROBLEM TO BE SOLVED: To provide a method of quantitatively analyzing red phosphorus in a resin by means of thermal decomposition GCMS, which is further improved in quantitative determination accuracy.
      SOLUTION: This method of determining the quantity of red phosphorus in a resin has processes of: performing thermal decomposition GCMS measurement on a prescribed separation condition to find hold time A of red phosphorus; finding a peak intensity ratio B by performing thermal decomposition GCMS measurement on a measuring specimen to confirm the detection of a peak of a mass spectrum within the same hold time as the hold time A, and dividing the measured peak area value by the amount of a specimen; confirming that the height of a peak of m/z=62 is 1.82-2.06 and the height of a peak of m/z=93 is 1.03-1.15 by assuming the height of a peak of m/z=124 to be 10; finding a relation between a peak intensity ratio C and a red phosphorus content on each of a plurality of standard specimens on the same separation condition; and also finding the amount of red phosphorus in the measuring specimen from this relation and the comparison to the intensity ratio B therewith.

    • The invention offers a method of quantitatively analyzing red phosphorus in a resin by the pyrolysis GCMS, the method having a further improved quantification accuracy. The method has the following steps: determining the retention time A of red phosphorus by performing pyrolysis GCMS measurement under a predetermined separating condition; determining the peak strength ratio B of the specimen to be measured by performing pyrolysis GCMS measurement to confirm that a peak of a mass spectrum is detected at the same retention time as the retention time A and by dividing the measured value of the peak area by the quantity of the specimen; confirming that when the height of the peak at an m/z of 124 in the mass spectrum is taken as 10, the height of the peak at an m/z of 62 lies in the 1.82-2.06 range and the height of the peak at an m/z of 93 lies in the 1.03-1.15 range; determining the relationship between the peak strength ratio C and the red-phosphorus content using multiple reference specimens under the same separating condition; and determining the quantity of the red phosphorus in the specimen to be measured by comparing the peak strength ratio B with the foregoing relationship.
