Determination of pyrimidifen in agricultural products by GC/MS
1999
Tsukioka, T. (Nagano-ken. Research Inst. for Health and Pollution (Japan)) | Terasawa, J. | Miyagawa, A. | Sato, M.
A method by GC/MS has been established for the determination of Pyrimidifen in agricaltural products. The Pyrimidifen in agricultural products is extracted with acetone, concentrated, and extracted with n-hexane. The solution is cleaned up with a Florisil column and subjected to a determination by GC/MS using p-terphenyl-d14 as the internal standard. This method is featured by the recovery over 80 % with its C .V. below 8 % and the detection limit 1 micro g/kg. This method, excellent in sensitivity and selectivity, is useful as a rutine analytical method for agricultural products.
