IKhadi lokuVavanya iNtsalela ye-Isoprocarb
Malunga
Le khithi ifanelekile ukufumanisa umgangatho we-isoprocarb eseleyo kwisampuli yekhukhamba entsha.
I-Isoprocarb sisibulali-zinambuzane esichukumisayo, esisebenza ngokukhawuleza, esisisibulala-zinambuzane esiyingozi kakhulu.Isetyenziswa ikakhulu ukulawula i-rice planthopper, i-rice cicada kunye nezinye izitshabalalisi kwirayisi, imithi yeziqhamo kunye nezityalo.Inetyhefu kwiinyosi kunye neentlanzi.
Ulwelo oluphezulu lwechromatography-tandem mass spectrometry yasetyenziselwa ukumisela intsalela ngenxa yokukhetha okuphezulu kunye nonyango olulula.Ckuthelekiswa neHPLCiindlela,ikhithi yethubonisa izinto ezilungileyo malunga nobuntununtunu, umda wobhaqo, izixhobo zobugcisa kunye neemfuno zexesha.
Amalungiselelo esampuli
(1)Ngaphambi kokuvavanya, iisampuli kufuneka zibuyiselwe kwiqondo lokushisa (20-30).℃).
Iisampulu ezintsha kufuneka zithathwe ukosula umhlaba kwaye zisikwe zibe ziingceba ezingaphantsi kwe-1cm yesikwere.
(2) Umlinganiselo we-1.00± 0.05g isampuli kwi-tube ye-polystyrene centrifuge ye-15mL, uze ungeze i-8mL isicatshulwa, uvale isiciko, u-oscillate phezulu naphantsi ngesandla kwi-30s, kwaye uyivumele imele i-1min.Ulwelo olunamandla yisampulu eza kuvavanywa.
Qaphela: Indlela yesampulu ibhekiselele kumanyathelo olawulo ohlolo lwesampulu yokhuseleko lokutya (aqsiq decree no. 15 of 2019).GB2763 2019 ireferensi.
Iziphumo
Engalunganga(-): Umgca T kunye nomgca C zombini zibomvu, umbala we-Line T unzulu kunokuba okanye ufana nomgca C, obonisa i-isoprocarb kwisampuli ingaphantsi kwe-LOD yekiti.
Okuhle(+): Umgca C ubomvu, umbala womgca T ubuthathaka kunomgca C, ebonisa i-isoprocarbl kwisampuli iphezulu kune-LOD yekiti.
Ayisebenzi: Umgca C awunambala, nto leyo ebonisa ukuba imicu ayisebenzi.Kule meko, nceda ufunde imiyalelo kwakhona, kwaye uphinde wenze uvavanyo ngomgca omtsha.
Ugcino
Gcina iikhithi kwindawo eyomileyo ye-2 ~ 30℃ kude nokukhanya.
Iikhithi ziya kusebenza kwiinyanga ezili-12.
