Chikafu chekuongorora chekuongorora kushanda
Thermo Scientific Hupenyu Sayenzi MS haina kungova netsika refu yetekinoroji, asi zvakare inoenderera mberi nekuvandudza. Quadrupole mass analysis yechokwadi conjugate hyperboloids inoenderana neinoretical electric field yebhuku rinoshandiswa pane ese TSQ® triple quadrupole mass spectrometers. Kubva payakavamba nyika yekutanga katatu quadrupole MS/MS (TSQ®) mass spectrometer muna 1980, TSQ® triple quadrupole mass spectrometer yakashandiswa zvakanyanya mukuchengetedza nharaunda, kurima, quarantine, kuchengetedza chikafu, nezvimwewo. masara emishonga yezvipembenene muchikafu, zvisaririra zvemishonga yezvipfuyo, mycotoxins, zvinowedzera, Zvokudya zvinovaka muviri uye zvinosvibisa organic Uye mamwe mapurojekiti ekukubatsira kusangana nyore nyore nekuwedzera kuomesera zvinodiwa.
pfupiso
5-nitroimidazoles ikirasi yemishonga ine 5-nitroimidazole ring structure, iyo ine anti-protozoal uye antibacterial basa. Bvunzo dzezuva nezuva dzinosanganisira sampuli dzakatorwa nemhuka senge zvipfuyo, zvigadzirwa zvemumvura, zvigadzirwa zvenyuchi, uye zvigadzirwa zvemukaka. Chinyorwa ichi chinoreva SN/T 1928-2007, GB/T 21318-2007, GB/T 22949-2008, GB/T 21995-2008, Ministry of Agriculture 1025 Chiziviso-22-2008, Ministry of Agriculture No. 104 SN/T01 2579-2010, yakapfava kubva kuGB/T 23410-2009, GB/T 23407-2009, GB/T 23406-2009, inzira yezviridzwa yekukurumidza kuona kwakasiyana siyana nitroimidazole zvinodhaka, yemukati mwero nzira Quantitative.
Pretreatment
Kune zvine hukama reagent zvinhu, yakajairwa gadziriso uye matura, uye sampuli nzira dzekugadzirira, ndapota tarisa kune ari pamusoro mazinga. Kuti uwane mamwe maitiro ezviridzwa, ndapota tarisa kune iri gwaro. (TSQ Triple Quadrupole Mass Spectrometer Concise Application Manual - Food Safety Testing)
chiridzwa
Iyo TSQ Triple Quadrupole LC/MS sisitimu inoshongedzerwa neyekupedzisira-yakanyanya kumanikidza mvura chikamu system.
Liquid phase condition
Mass spectrometry mamiriro
SRM mamiriro
Experimental result
Yakajairika chromatogram (yakatorwa kubva kuGB/T 23410-2009 appendix)
mukupedzisa
Pakati penzira dziri pamusoro penyika dzekuongorora, muganho wekuona wemishonga ye nitrofuran mumatrices akasiyana ndeye 1.0-5.0 μg/kg. Iyo nzira inokwanisa zvizere kuzadzisa zvinodikanwa zvemukati uye zvepasirese zvigadziro zvekunzwa uye kuberekazve kwezvakajairwa kudzora nzira.
