Kusanthula kwa kayendedwe ka chakudya

Thermo Scientific Life Science MS sikuti imangokhala ndi chikhalidwe chaukadaulo, komanso ikupitilizabe kupanga zatsopano. Kusanthula kwa Quadrupole kuchuluka kwa ma conbugate hyperboloids owona omwe amagwirizana ndi gawo lamagetsi lamaukadaulo amagwiritsidwa ntchito pa ma spectrometers onse a TSQ® patatu a quadrupole. Chiyambireni makina owerengera apadziko lonse lapansi a MS / MS (TSQ®) padziko lonse lapansi mu 1980, TSQ® katatu yama quadrupole mass spectrometer yakhala ikugwiritsidwa ntchito kwambiri poteteza zachilengedwe, ulimi, kupatula anthu, chitetezo cha chakudya, ndi zina zambiri. Kuyesa kosanthula, kotheka kuyesa kuyerekezera kuyesa zitsanzo zazikulu za mbewu, ziweto ndi nkhuku, zopangidwa ndi mkaka ndi zakudya zina zofananira, monga zotsalira za mankhwala ophera tizilombo, zotsalira zamankhwala azowona zanyama, mycotoxins, zowonjezera, Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zakudya Zam'madzi ndi zina zotero kuti zikuthandizeni kukumana nazo mosavuta malamulo okhwima okhwima.

chidule

5-nitroimidazoles ndi gulu la mankhwala okhala ndi 5-nitroimidazole ring ring, omwe ali ndi anti-protozoal ndi antibacterial activity. Kuyesedwa kwa tsiku ndi tsiku kumakhudza zitsanzo za nyama monga ziweto, zopangidwa m'madzi, zopangira 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, yosavuta kuchokera ku GB / T 23410-2009, GB / T 23407-2009, GB / T 23406-2009, ndi chida chothandizira kuzindikira msanga zotsalira zamankhwala a nitroimidazole, njira yoyenera mkati Zambiri.

Kukonzekera

Kwa zida zokhudzana ndi reagent, kasinthidwe kofananira ndi nkhokwe, ndi njira zokonzekera zitsanzo, chonde onani milingo yomwe ili pamwambapa. Kuti mugwiritse ntchito zida zofananira, chonde onani izi. (TSQ Triple Quadrupole Mass Spectrometer Concise Application Manual - Kuyesa Kwachakudya)

chida

Dongosolo la TSQ Triple Quadrupole LC / MS lili ndi pulogalamu yamagetsi yamagetsi othamanga kwambiri.

Pomaliza

Mwa njira zomwe zanenedwa pamwambapa, kuchuluka kwa mankhwala a nitrofuran m'matrices osiyanasiyana ndi 1.0-5.0 μg / kg. Njirayi imakwanitsa kukwaniritsa zofunikira za malamulo apanyumba komanso apadziko lonse lapansi pakukhudzidwa ndikuberekanso njira zodziwikiratu.
