Kev txiav txim siab txog cov ntsiab lus
Cov ntaub ntawv pov thawj pov thawj cov ntaub ntawv
ntsuas los ntawm kev ua haujlwm siab ua kua chromatography (General 0512).
chromatographic tej yam kev mob thiab system suitability test
silica gel txuas nrog octylsilane ua muab tub lim; Sodium pentanesulfonate tov (sodium pentanesulfonate 1.5g, ammonium dihydrogen phosphate 3.0g, dej 950ml kom yaj, kho pH rau nrog phosphoric acid, dilute mus rau 1000ml nrog dej) - Methanol (65:35) raws li mobile theem, ntws tus nqi ntawm 1 ml. feeb, nrhiav wavelength ntawm 287mn ua. Siv cov txheej txheem siv tshuaj 20u1 nyob rau hauv cov khoom ntawm cov khoom muaj feem xyuam thiab txhaj rau hauv tib neeg Liquid Chromatograph. Lub sijhawm khaws cia ntawm lomefloxacin yog kwv yees li 9 feeb, thiab qhov sib cais ntawm qhov siab tshaj plaws ntawm lub sijhawm khaws cia ntawm kwv yees li 0.8 thiab lomefloxacin ncov yuav tsum siab dua 2.0, kev daws teeb meem ntawm lomefloxacin ncov thiab impurity ncov ntawm tus txheeb ze tuav lub sijhawm 1.1 yuav tsum. ua tau raws li qhov yuav tsum tau ua.
soj ntsuam
coj tus nqi ntawm cov khoom no, precision hnyav, ntxiv rau mobile theem dissolution thiab quantitative dilution ua nyob rau hauv txhua lml uas muaj li ntawm 0. Cov lmg tov yog siv raws li cov tshuaj ntsuam xyuas, thiab 20ul tau txhaj rau hauv cov kua chromatograph nrog precision, thiab cov chromatogram. tau sau tseg. Lwm yam tshuaj lomefloxacin siv tau thiab txiav txim siab los ntawm tib txoj kev. Cov ntsiab lus ntawm lomefloxacin (C17H19F2N303) hauv cov qauv tau suav los ntawm thaj chaw ncov raws li tus qauv txheej txheem sab nraud.
