Njira yowunikira
Kufotokozera
Tengani pafupifupi 10ml chitsanzo mu mbale yagalasi yoyera ndi youma ndikuwunika.
Kuzungulira kwachindunji
Tumizani molondola pafupifupi 1.0g ya zitsanzo ku 100ml voliyumu botolo ndi kusungunuka mu10 ml ya chloroform, ndiye kuchepetsedwa ndi chloroform 100ml ndi kusakaniza.
Yezerani kusinthasintha kwa kuwala kwa chitsanzo choyesera pa 25ºC ndi 589nm wavelengthwerengerani kuzungulira kwachindunji monga momwe mwapatsidwa.
[α]25D = (v×a)/[w×(1-b)]
[α]25D: kusinthasintha kwapadera kwa mayesochitsanzo;α: mawonekedwe ozunguliradigiri ya angular;w: kulemera kwachitsanzo (g);
v: kuchuluka (mL);
b: Madzi (%)
