<P>PROBLEM TO BE SOLVED: To provide a fluorine analysis method and a fluorine analysis system which is suitably used in a daily check test and is capable of easily and rapidly quantifying fluorine in inorganic materials, especially cement, by a thermal decomposition method which does not include humidification. Ž<P>SOLUTION: The fluorine analysis method performs quantitative analysis by extracting fluorine and comprises: mixing a reaction accelerator to the sample to be analyzed, and heating the mixture at a temperature 1,000 to 1,100°C with an non-humidified air as a carrier gas; collecting the fluoride generated in an absorption liquid; and quantifying the fluoride.
