Kev soj ntsuam kev nyab xeeb ntawm zaub mov ua haujlwm
Thermo Scientific Life Science MS tsis tsuas yog muaj kev coj noj coj ua ntev ntawm kev siv thev naus laus zis, tab sis tseem txuas ntxiv tsim kho tshiab. Quadrupole loj tsom xam ntawm qhov tseeb conjugate hyperboloids uas haum rau lub zoo meej theoretical hluav taws xob teb ntawm ib phau ntawv yog siv rau tag nrho TSQ® triple quadrupole huab hwm coj spectrometers. Txij li thaum pib lub ntiaj teb thawj triple quadrupole MS / MS (TSQ®) huab hwm coj spectrometer nyob rau hauv 1980, TSQ® triple quadrupole huab hwm coj spectrometer tau siv dav hauv kev tiv thaiv ib puag ncig, kev ua liaj ua teb, kev cais tawm, kev nyab xeeb khoom noj, thiab lwm yam. Kev soj ntsuam kev soj ntsuam, muaj peev xwm ntawm kev soj ntsuam niaj hnub soj ntsuam ntawm cov khoom lag luam loj thiab cov khoom noj khoom haus, cov khoom noj khoom haus thiab cov khoom noj khoom haus. Cov khoom noj uas tau ua tiav, xws li tshuaj tua kab nyob hauv cov zaub mov, cov tshuaj tua tsiaj seem, mycotoxins, additives, Khoom noj khoom haus ntxiv thiab cov kuab paug organic Thiab lwm cov haujlwm los pab koj yooj yim ua tau raws li cov kev cai nruj zuj zus ntxiv.
Cov ntsiab lus
5-nitroimidazoles yog ib chav kawm ntawm cov tshuaj uas muaj 5-nitroimidazole nplhaib qauv, uas muaj anti-protozoal thiab antibacterial kev ua si. Kev ntsuam xyuas txhua hnub suav nrog cov qauv coj los ntawm cov tsiaj xws li tsiaj txhu, cov khoom hauv dej, cov khoom muv, thiab cov khoom siv mis nyuj. Tsab xov xwm no hais txog SN/T 1928-2007, GB/T 21318-2007, GB/T 22949-2008, GB/T 21995-2008, Ministry of Agriculture 1025 Tshaj Tawm-22-2008, Ministry of Agriculture No. 14820/SNouncement 2579-2010, yooj yim los ntawm GB / T 23410-2009, GB / T 23407-2009, GB / T 23406-2009, yog ib qho cuab yeej siv rau kev tshawb nrhiav sai ntawm ntau yam nitroimidazole cov tshuaj seem, sab hauv txheej txheem Quantitative.
Kev kho mob ua ntej
Rau cov ntaub ntawv reagent muaj feem xyuam, kev teeb tsa tus qauv thiab kev khaws cia, thiab cov qauv kev npaj, thov mus saib cov qauv saum toj no. Rau cov txheej txheem ntsuas ntsig txog, thov saib daim ntawv no. (TSQ Triple Quadrupole Mass Spectrometer Concise Application Manual - Food Safety Testing)
ntsuas
TSQ Triple Quadrupole LC / MS system yog nruab nrog lub tshuab hluav taws xob siab siab siab.

nyob rau hauv xaus
Ntawm cov txheej txheem tshawb nrhiav hauv tebchaws saum toj no, qhov kev tshawb pom txwv tsis pub siv tshuaj nitrofuran hauv cov matrices sib txawv yog 1.0-5.0 μg / kg. Cov txheej txheem muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm cov qauv kev tswj hwm hauv tebchaws thiab thoob ntiaj teb rau kev nkag siab zoo thiab kev tsim tawm ntawm cov txheej txheem kev cai.
