Thaum nrhiav Elcatonin (CAS 60731-46-6) hmoov rau kev tshawb fawb lossis kev txhim kho, ib qho ntawm cov ntsiab lus purity feem pua ib leeg tsis piav txog cov khoom zoo. Kev txheeb xyuas tus kheej, cov ntsiab lus peptide, impurity profile thiab batch traceability txhua teb cov lus nug sib txawv txog cov khoom.
Phau ntawv qhia no piav qhia seb yuav ntsuas li casElcatonin hmoovzoo, HPLC thiab LC yog dab tsi-MS txheeb xyuas, thiab yuav ua li cas los tshuaj xyuas ib pawg- Daim Ntawv Pov Thawj Tshwj Xeeb ntawm Kev Ntsuam Xyuas (COA).
Vim li cas Elcatonin Powder Zoo Yuav Tsum Tau Muaj Ntau Tshaj Li Kev Cai Purity
Ib qho "98% purity" thov tsis tuaj yeem tsim:
- Seb cov khoom puas yog Elcatonin tiag tiag thiab tsis yog lwm qhov calcitonin analogue
- Seb purity yog ntsuas los ntawm chromatographic ncov cheeb tsam los yog los ntawm qhov hnyav assay
- Seb ntsev daim ntawv, ya raws thiab seem seem yog suav rau
- Seb lub batch sib phim cov ntaub ntawv nrog
Chromatographic purity, peptide cov ntsiab lus, kev lees paub tus kheej thiab cov tswv yim muaj peev xwm yog cov cwj pwm zoo sib txawv. Txhua tus yuav tsum tau soj ntsuam ntawm nws tus kheej cov ntsiab lus.
Yuav Ua Li Cas Txheeb Xyuas Elcatonin Tus Kheej
Txheeb xyuas cov hauv qab no tiv thaiv cov ntaub ntawv xa khoom:

- Muaj thiab qauv ntawm impurity peaks
- Batch-rau-batch sib xws ntawm chromatographic profile
Qhov loj - feem pua ntawm thaj chaw ncov piav qhia txog kev huv ntawm tus txheeb ze chromatographic, tsis yog cov ntsiab lus peptide kiag li los ntawm qhov hnyav. Cov txiaj ntsig tau nyob ntawm txoj kev sib cais, kev tshawb nrhiav pom, cov cai sib koom ua ke thiab qhia hauv paus.
HPLC cov txiaj ntsig yuav tsum tau txhais nrog rau txoj kev tshuaj ntsuam xyuas, cov txheej txheem tsim nyog thiab cov khoom siv - tshwj xeeb tshwj xeeb. Lub ntsiab tseem ceeb - feem pua ntawm thaj chaw ncov ib leeg tsis tsim kom muaj tus kheej, cov ntsiab lus tseeb lossis kev ua haujlwm lom neeg.
Cov ntaub ntawv purity los ntawm cov neeg muag khoom sib txawv tsis sib piv ncaj qha tshwj tsis yog cov txheej txheem thiab kev suav cov hauv paus sib npaug.
LC-MS Testing: Molecular Identity Confirmation
LC-MS ntsuas molecular mass thiab txhawb kev tshuaj xyuas tus kheej:
- Sib piv pom huab hwm coj-rau- tus nqi sib piv thiab them cov xeev nrog cov kev xav tau ntawm tus lej molecular
- Kev sib tw loj txhawb tus kheej tab sis tsis yog los ntawm nws tus kheej tsim kom tiav ib ntus lossis stereochemical purity
- Rau siab -molecular- hnyav peptides xws li Elcatonin, txhais ntau- them ions es tsis yog muab piv rau tib lub ncov nyoos ncaj qha nrog qhov nruab nrab molecular hnyav
Qhov twg yuav tsum muaj kev ruaj ntseg zoo dua qub, thov kev txhawb nqa huab hwm coj thiab xav txog cov txheej txheem kev tshuaj xyuas orthogonal ntxiv tsim nyog rau cov khoom siv thiab daim ntawv thov.
Kev tswj hwm kev taw qhia ntawm cov peptides hluavtaws sib tham txog kev txheeb xyuas thiab kev ua tus cwj pwm ntawm peptide-txog impurities hauv cov ntsiab lus tshwj xeeb ntawm kev tsim kho tshuaj; nws yuav tsum tsis txhob nyeem raws li qhov yuav tsum tau xeem tus qauv rau tag nrho Elcatonin raw- khoom yuav khoom.
