Although red phosphorus is used as a flame retardant for polymer materials, no analysis methods for it in resins has been established. Analysis methods for red phosphorus in resins were investigated using pyrolysis-gas chromatograpy/mass spectrometry (Py-GC/MS) by paying attention to the fact that it has a sublimation property. We found that the mass spectrum of red phosphorus shows a series of ions at <i>m/z</i> = 62, 93 and 124, and a fragment pattern indicating that red phosphorus (<i>P</i><sub>4</sub> = 124, <i>P</i> = 31) was pyrolytically decomposed. The coefficient of the correlation between the content of red phosphorus in the resin and the peak intensity in Py-GC/MS was 0.9781. The relative standard deviations of this analysis method was 6.29% (<i>n</i> = 5). Py-GC/MS was applicable not only to qualitative analysis but also to the quantitative analysis of red phosphorus.
