Customized kev pab cuam ntawm tshuaj siv cov ntaub ntawv ntawm tsoos suav Med-icine
Jiangsu Yongjian Pharmaceutical Technology Co., Ltd. yog feem ntau koom nrog hauv kev tshawb fawb ntawm cov tshuaj nquag ntawm cov tshuaj suav tshuaj rau ntau tshaj kaum xyoo.Txog tam sim no, lub tuam txhab tau ua qhov kev tshawb fawb tob txog ntau dua 100 hom kev siv tshuaj suav tshuaj, thiab tau rho tawm ntau txhiab yam tshuaj.
Lub tuam txhab muaj cov neeg ua haujlwm R & D sab saum toj thiab cov khoom siv tshuaj ntsuam xyuas zoo tshaj plaws hauv kev lag luam, thiab tau ua haujlwm ntau pua lub tsev tshawb fawb txog kev tshawb fawb.Nws tuaj yeem ua tau sai thiab ua tau raws li cov neeg siv khoom xav tau.
Tshuaj impurity sib cais, kev npaj thiab kev pom zoo kev pab cuam
Impurities nyob rau hauv cov tshuaj yog ze ze rau qhov zoo, kev ruaj ntseg thiab stability ntawm cov tshuaj.Kev npaj thiab qauv kev lees paub ntawm impurities hauv cov tshuaj tuaj yeem pab peb nkag siab txog txoj hauv kev ntawm impurities thiab muab lub hauv paus rau kev txhim kho cov txheej txheem ntau lawm.Yog li ntawd, kev npaj thiab kev sib cais ntawm impurities yog qhov tseem ceeb heev rau kev tshawb fawb txog tshuaj thiab kev loj hlob.
Txawm li cas los xij, cov ntsiab lus ntawm impurities nyob rau hauv cov tshuaj yog tsawg, lub hauv paus yog dav, thiab cov qauv yog feem ntau zoo ib yam li lub hauv paus ntsiab lus.Dab tsi thev naus laus zis tuaj yeem siv los sib cais sai sai thiab ntxuav tag nrho cov impurities hauv cov tshuaj ib los ntawm ib qho?Cov txheej txheem thiab cov txheej txheem twg yog siv los lees paub cov qauv ntawm cov impurities no?Qhov no yog qhov nyuaj thiab kev sib tw uas tau ntsib los ntawm ntau lub chaw muag tshuaj, tshwj xeeb tshaj yog cov chaw muag tshuaj ntawm cov tshuaj cog thiab tshuaj suav patent.
Raws li cov kev xav tau zoo li no, lub tuam txhab tau tsim cov tshuaj impurity cais thiab purification cov kev pab cuam.Kev cia siab rau nuclear magnetic resonance, huab hwm coj spectrometry thiab lwm yam khoom siv thiab thev naus laus zis, lub tuam txhab tuaj yeem txheeb xyuas cov qauv ntawm cov khoom sib cais, kom ua tau raws li cov kev xav tau ntawm cov neeg siv khoom.
