Establishment of sensitive determination method of historical lacquer film.

与常规的PyGC/MS相比，该方法的灵敏度提高了约10倍。显然，考虑到在通常的方法中无法检测到的情况，这是一种灵敏度的十倍或更多。另一方面，除了Rhus vernicifluum之外，没有进展到由于变质而无法指定地点的状态也变得清晰起来。然而，高敏化的效果在实际样品分析的例子中得到了肯定（来自泰国，从结果中得出）。

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).
