Establishment of sensitive determination method of historical lacquer film.

与常规的PYGC/MS联用方法相比，该方法对漆树的灵敏度提高了10倍。很明显，考虑到它不是用通常的方法检测出来的情况，它的敏感度是十倍甚至更高。另一方面，除了漆树外，没有进展到由于变质而无法确定地点的状态也变得清晰起来。然而，在对实际样品(来自泰国并从结果中得出)的分析实例中，肯定了高度增敏的效果。

It succeeded in obtaining about ten times the sensibility in the method developed in the present study compared with usual PyGC/MS for 'Rhus vernicifluum'. It was apparent that it was a sensibility ten times or more , considering the case where it is not detected in a usual method. On the other hand, not progressing to the state that the locality was not able to be specified due to deterioration either became clear, except for Rhus vernicifluum. However, the effect of the high sensitization was affirmed in the example of analysis of an actual sample (from Thailand and turned out from the consequence).
