 note = {The effects of stepwise heating of sample, addition of not only CuO but also Cu and Ag in a sealed tube on sample combustion, and use of a n-pentane/liq.N2 trap and/or a Sulfix reagent on sample CO2 purification upon sample graphitization, 14C ages and δ13C values were investigated. The sample used is a filter made from PES including sulfur. The sample combustion by stepwise heating was more effective in complete conversion of carbon in samples to CO2, and the addition of Cu and Ag on sample combustion was effective in removal of sulfur contained in sample. Furthermore, the treatment of sample C02 using a Sulfix reagent became worse the measurement precision of 14C and δ13C values probably due to isotopic fractionation during reaction of sample CO2 with Sulfix. From the results, the best sample preparation method for 14C ages and δl3C analysis could be that a sample is combusted with CuO, Cu and Ag by stepwise heating. Purification of CO2 extracted from the sample using n-pentane/liq.N2 trap could not be needed in this preparation method.},
