Kuthamanga kwa 0.5ml/s, FMOC-L-VALINOL nsonga pa masekondi 19, FMOC-D-VALINOL pachimake pa masekondi 58.
Njira yodziwira kusinthasintha kwa Valinol
1. Pambuyo poyatsa ufa, yatsani chosinthira mphamvu ndikudikirira 15min kuti nyali ya sodium ikhale yolimba.
2. Yatsani chosinthira chowunikira, ndipo nyali ya sodium imayatsidwa pansi pamagetsi a DC.
3. Konzani chubu choyesera.
4, mu chubu wakonzedwa kubaya trichloromethane zosungunulira, akanikizire "zero" kiyi, kuti chiwonetsero ndi ziro.
5. Chotsani chosungunulira chopanda kanthu ndikubaya chitsanzo kuti chiyesedwe.
