<p><P>PROBLEM TO BE SOLVED: To perform qualitative/quantitative analysis in an extremely precise and efficient manner by definitely separating other additive contained in a resin and a bromine-based fire retardant which is an additive of a measuring target at the normal temperature. <P>SOLUTION: A resin, which contains a bromine-based fire retardant and another additive, is dissolved in an organic solvent such as THF or the like to prepare a solution and the supernatant of this solution is dripped on a planar plate to be dried and solidified. Thereafter, the dried and solidified bromine-based fire retardant-containing resin is used as a sample to measure a spectrum by infrared spectral analysis or Raman spectral analysis to qualitatively/quantitatively analyze the bromine-based fire retardant in the resin. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
