| Research Abstract |
I researched Japan/China identification of methamidophos as bothered "poisoned gyoza". For high precision and accuracy, the many reagents in combustion tube were tested. As the results, the copper oxide with nickel and platinum was selected. In addition, I installed cryofocusing system using liquid nitrogen between combustion and IRMS and can analyze low concentration of methamidophos. Finally, Chinese methamidophos pesticide is very closed to a methamidophos reagent bought in Japan by using δ^<13>C.
