Dimefluthrin CAS 271241-14-6 yog dab tsi?

Tam sim no, feem ntau ntawm cov tetrafluthrin disc yoov tshaj cum tau txais txoj kev tshuaj ntsuam xyuas los ntawm Nyiv lub tuam txhab Sumitomo Chemical, uas yog, GC-ECD (electron capture detector) tsom xam, thiab cov txheej txheem pretreatment yog cumbersome. Yog li ntawd, nws yog ib qho tsim nyog yuav tau kawm ib txoj kev tshuaj ntsuam uas tsim nyog rau kev tsim khoom tiag tiag.
Cov ntsiab lus ntawm tetrafluthrin tau txheeb xyuas los ntawm cov roj chromatography. Nrog fenothrin raws li tus qauv sab hauv, DB-1 quartz capillary kem tau siv rau kev sib cais thiab FID nrhiav pom. Cov txiaj ntsig kev soj ntsuam tau pom tias cov kab sib txuas sib txuas ntawm tetrafluthrin yog 0.9991, tus qauv sib txawv yog 0.000049, qhov sib txawv ntawm qhov sib txawv yog 0.31%, thiab tus nqi rov qab yog 97.00% thiab 99.44%.

Daim ntawv thov

Raws li ib yam tshiab ntawm pyrethroid hygienic insecticide, transfluthrin muaj kev tswj siab ntawm yoov tshaj cum uas tiv taus allethrin thiab propargyl. Cov tshuaj tua kab muaj kev nyab xeeb rau tib neeg lub cev thiab tsis ua qias neeg ib puag ncig, thiab qhov ntau npaum li cas ntawm nws qhov kev npaj yog tsawg li 0.015%.
