Kusanthula kwachitetezo cha chakudya kumayendera
Thermo Scientific Life Science MS sikuti ili ndi miyambo yayitali yaukadaulo, komanso ikupitiliza kupanga.Quadrupole mass analysis of true conjugate hyperboloids yomwe imagwirizana bwino ndi gawo lamagetsi lamagetsi la bukhuli imagwiritsidwa ntchito pa TSQ® triple quadrupole mass spectrometers.Chiyambireni makina owonera katatu padziko lonse lapansi a quadrupole MS/MS (TSQ®) mu 1980, TSQ® triple quadrupole mass spectrometer yakhala ikugwiritsidwa ntchito kwambiri poteteza zachilengedwe, ulimi, kuika kwaokha, chitetezo cha chakudya, ndi zina zambiri. kuyesa zitsanzo zazikulu za mbewu, ziweto ndi nkhuku, mkaka ndi zakudya zina zosinthidwa, monga zotsalira za mankhwala ophera tizilombo m'zakudya, zotsalira zamankhwala azinyama, ma mycotoxins, zowonjezera, Zakudya zopatsa thanzi ndi zowononga zachilengedwe Ndi ntchito zina zokuthandizani kuti mukwaniritse mosavuta kuchulukirachulukira kofunikira pakuwongolera.
mwachidule
5-nitroimidazoles ndi gulu la mankhwala okhala ndi 5-nitroimidazole mphete, omwe ali ndi anti-protozoal ndi antibacterial ntchito.Kuyesa kwa tsiku ndi tsiku kumaphatikizapo zitsanzo zochokera ku nyama monga ziweto, zam'madzi, njuchi, ndi mkaka.Nkhaniyi ikunena za SN/T 1928-2007, GB/T 21318-2007, GB/T 22949-2008, GB/T 21995-2008, Ministry of Agriculture 1025 Announcement-22-2008, Ministry of Agriculture No. 1486 Announcement 4-2010, SN/T 2579-2010, chosavuta kuchokera GB/T 23410-2009, GB/T 23407-2009, GB/T 23406-2009, ndi chida njira kudziwika mofulumira zosiyanasiyana nitroimidazole zotsalira mankhwala, mkati muyezo njira Zambiri.
Kuchiza
Pazinthu zokhudzana ndi reagent, kasinthidwe wamba ndi nkhokwe, ndi njira zokonzekera zitsanzo, chonde onani zomwe zili pamwambapa.Kuti mudziwe njira zofananira ndi zida, chonde onani chikalatachi.( TSQ Triple Quadrupole Mass Spectrometer Concise Application Manual - Food Safety Testing)
chida
Dongosolo la TSQ Triple Quadrupole LC/MS lili ndi makina opitilira mphamvu kwambiri amadzimadzi.
Mkhalidwe wagawo lamadzi
Misa spectrometry chikhalidwe
Mkhalidwe wa SRM
Zotsatira zoyeserera
Chromatogram yodziwika bwino (yochokera ku GB/T 23410-2009 appendix)
Pomaliza
Mwa njira zodziwira zomwe zili pamwambazi, malire ozindikira mankhwala a nitrofuran m'matrices osiyanasiyana ndi 1.0-5.0 μg/kg.Njirayi ndi yokwanira kukwaniritsa zofunikira za malamulo apakhomo ndi apadziko lonse kuti amve komanso kuberekana kwa njira zoyendetsera bwino.
