Refractometer, tseem hu ua refractometer, yog ib qho cuab yeej siv lub teeb los ntsuas qhov concentration ntawm cov kua, thiab siv los ntsuas qhov ntsuas refractive, birefringence, thiab cov khoom kho qhov muag. Refractometer tuaj yeem muab faib ua tes tuav refractometer, qab zib refractometer, zib ntab refractometer, lub pov haum refractometer, digital zaub refractometer, tsis siv neeg refractometer thiab online refractometer.
1. Ntsuas qhov ntsuas qhov taw qhia
Refractive index yog lub cev tsis tu ncua ntawm qhov teeb meem, thiab txhua yam khoom muaj nws tus yam ntxwv refractive index. Refractometers tuaj yeem siv los ntsuas cov tshuaj, tsw thiab tshuaj tsw qab, iav, yas thiab lwm yam khoom.
2. Ntsuas cov suab thaj
Lub refractometer tuaj yeem siv los ntsuas qhov Brix tus nqi ntawm cov qauv uas muaj suab thaj, xws li kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, jam, zib ntab, thiab lwm yam. Tus nqi ntsuas yog cuam tshuam nrog cov piam thaj concentration ntawm cov qauv ntsuas, thiab Brix scale yeej sawv cev rau qhov concentration. Ib qho kev daws teeb meem ntawm sucrose. Tus nqi hloov pauv ntawm tus nqi Brix thiab qhov ntsuas qhov ntsuas tsis pom yog cov ntaub ntawv siv ICUMSA (International Association of Methods of Sugar Analysis).
3. Ntsuas qhov concentration ntawm cov zaub mov
Cov kua txiv hmab txiv ntoo thiab lwm cov kua ntsw, cov kua ntsev thiab lwm yam kua zaub muaj suab thaj, ntsev thiab lwm yam tshuaj. Kev ntsuas refractometer yog proportional rau cov ntsiab lus soluble solids nyob rau hauv cov kev daws teeb meem, yog li ntawd tus nqi Brix sawv cev rau tag nrho cov soluble solids cov ntsiab lus nyob rau hauv cov tshuaj.
4. Ntsuas qhov concentration ntawm cov tshuaj aqueous
Lub refractometer tuaj yeem siv los txiav txim siab cov ntsiab lus ntawm aqueous daws xws li roj-raws li kev daws teeb meem, tshuaj thiab cov khoom siv tshuaj hnyav xws li roj cav, tshuaj ntxuav tes, glycol, cesium chloride, sodium hydroxide thiab lwm yam tshuaj. Muaj kev sib piv ntawm tus nqi Brix thiab qhov concentration ntawm txhua qhov kev daws teeb meem. Qhov kev daws teeb meem tuaj yeem txiav txim siab los ntawm Brix tus nqi ntsuas los ntawm refractometer thiab lub rooj hloov dua siab tshiab. Tus nqi Brix yog qhov ntsuas yooj yim los txiav txim siab cov ntsiab lus soluble hauv cov tshuaj.
