Title:
METHOD FOR PRODUCING STANDARD SAMPLE FOR USE IN QUANTITATIVE DETERMINATION OF RED PHOSPHORUS IN RESIN
Document Type and Number:
WIPO Patent Application WO/2010/140496
Kind Code:
A1
Abstract:
Disclosed are a method for producing a standard sample which ensures the uniform dispersion of a predetermined concentration of red phosphorous even in an extremely small amount, and an assay method which is a method for quantitatively determining red phosphorous in a resin by pyrolysis GCMS, characterized by using the standard sample. Specifically disclosed are a method for producing a standard sample for use in the quantitative determination of red phosphorus in a resin, characterized by comprising a step of preparing a red phosphorus-containing compound by weighing a predetermined amount of red phosphorous and uniformly mixing the red phosphorous in a resin, a step of crushing the red phosphorus-containing compound so as to reduce the number of particles having a largest dimension of 5 μm or more to one-twentieth or less of the number of particles having a largest dimension of 1 μm or more but less than 5 μm, and a step of preparing a standard sample by weighing about 0.05 to 10 mg, preferably about 0.1 to 0.5 mg of the crushed red phosphorous-containing compound, and an assay method which is a method for quantitatively determining red phosphorous in a resin by pyrolysis GCMS, characterized by using the standard sample.
