Kev txiav txim siab ntawm cov suab thaj hauv cov suab thaj hloov pauv los ntawm txoj kev sib hloov refractive
Carbohydrates yog cov khoom tseem ceeb hauv kev npaj tshuaj. Suav Pharmacopoeia suav nrog cov piam thaj ua cov tshuaj noj zaub mov thiab sucrose raws li kev siv tshuaj kho qhov muag hauv kev npaj tshuaj. Sucrose yog ib qho disaccharide tsim los ntawm polymerization ntawm ib molecule ntawm qabzib thiab ib tug molecule ntawm fructose. Nws crystallinity tso cai rau nws muaj nyob rau ntawm ib tug siab concentration nyob rau hauv cov kua los yog semi-kua formulations xws li decoctions. Thaum lub sij hawm cia, nws yog nquag re crystallization, uas cuam tshuam rau cov uniformity thiab stability ntawm formulation. Txhawm rau kom kov yeej crystallization, txhim kho qab zib thiab antioxidant zog, thiab ua kom yooj yim shaping, sucrose yog yaj nyob rau hauv ib tug me me dej thiab tuav ntawm 110-115 degree rau 2 teev nyob rau hauv lub xub ntiag ntawm 0.1% tartaric acid los tsim invert qab zib. Zoo li zib ntab, invert qab zib feem ntau yog tsim los ntawm kev sib xyaw ntawm qabzib thiab fructose. Ntau lub tuam txhab siv nws hloov pauv sucrose thiab zib ntab hauv kev lag luam kws tshuaj thiab zaub mov. Yuav kom tswj tau qhov zoo ntawm invert qab zib thiab nws cov formulations, peb siv lub Repo-3 invert qab zib refractometer los txiav txim cov ntsiab lus ntawm qabzib thiab fructose nyob rau hauv invert qab zib thiab decoction, uas muaj peev xwm soj ntsuam tus nqi hloov dua siab tshiab ntawm invert qab zib thaum lub sij hawm. kev hloov dua siab tshiab thiab cov khoom kawg theem.
Cov sucrose thiab zib ntab hauv cov tshuaj pleev yuav tsum tau ua kom zoo thiab ntxiv kom tshem tawm cov impurities, tua cov kab mob, txo cov dej noo, thiab tiv thaiv qhov tshwm sim ntawm "xuab zeb rov qab" (crystallization ntawm qab zib tom qab cia rau qee lub sijhawm) hauv cov tshuaj pleev. Cov txheej txheem ntawm refining qab zib yog ntxiv ib nrab ntawm cov suab thaj hauv dej thiab 0.1% tartaric acid rau sucrose, kub thiab yaj nws, cia nws boil me ntsis, kom txog thaum cov kua qab zib tig golden daj, thiab hloov dua siab tshiab tus nqi nce mus txog 40% mus rau 50%.
Cov xuab zeb rov qab yog cuam tshuam nrog tag nrho cov ntsiab lus qab zib thiab hloov suab thaj hauv decoction. Tag nrho cov ntsiab lus qab zib yuav tsum tau tswj qis dua 85%, thiab tus nqi hloov pauv yuav tsum tswj ntawm 40-50%. Lub Repo-3 qab zib hloov pauv kho qhov muag hloov txhua lub tshuab tuaj yeem ntsuas cov ntsiab lus ntawm ntau cov suab thaj hauv decoctions, suav nrog fructose, qabzib, thiab sucrose.

Cov txheej txheem ntau npaum li cas feem ntau siv cov khoom txo qis thiab cov kua chromatography cov khoom ntawm cov suab thaj, thiab siv cov txheej txheem xws li redox titration thiab chromatographic txiav txim kom muaj nuj nqis. Thaum soj ntsuam nrog qhov sib piv ntawm cov ntsiab lus qab zib hauv cov xeev sib xyaw thiab cov tshuaj formulations, nws yooj yim rau kev cuam tshuam thiab txo qhov ntsuas qhov tseeb. Lub Repo-3 hloov dua siab tshiab qab zib refractive rotation all-in-one tshuab yog tsim nyog rau kev ntsuas cov ntsiab lus thiab feem ntawm cov suab thaj nyob rau hauv lub xeev sib xyaw.
Calibration standard tov rau ATAGO refractometer thiab qab zib ntsuas
Lub ATAGO refractometer thiab qab zib ntsuas ntsuas tau ntsuas rau txhua yam khoom ua ntej xa khoom, thiab yuav tsis muaj qhov sib txawv ntawm qhov ntsuas tshwj tsis yog tias muaj xwm txheej tshwm sim thaum xa khoom. Tab sis yog tias kev sib txawv tshwm sim tom qab siv mus ntev lossis cuam tshuam rau sab nraud, nws yog qhov yuav tsum tau kho qhov xoom point. Rau cov refractometers uas tsis tuaj yeem raug xoom nrog dej, thov siv cov txheej txheem daws teeb meem los kho qhov xoom taw tes.
