Iindlela Zokuhlalutya Ubunyulu
Ukucoceka kwe-isopropanol ngokuqhelekileyo kugqitywa ngeendlela zokuhlalutya iikhemikhali, kubandakanywa i-chromatography yegesi (GC), i-high-performance liquid chromatography (HPLC), kunye neendlela ezinqabileyo ze-chromatography (TLC). Imigangatho yokufumanisa i-isopropanol ephezulu yococeko ngokuqhelekileyo iyahluka ngokusetyenziswa kwayo. Ngokomzekelo, i-isopropanol esetyenziswe kwi-biopharmaceuticals ifuna ukufikelela ekucocekeni kwe-99.99%, ngelixa isetyenziswe kwimveliso yezoshishino inokufuna ukufikelela kwi-99% yobunyulu.
Impembelelo yoBunyulu kwiZicelo
I-isopropanol ye-high-purity ibaluleke kakhulu kwizicelo ze-biopharmaceutical kuba ucoceko oluphezulu kakhulu luyafuneka ukuze kuqinisekiswe ukuzinza kunye nokusebenza kwamachiza. Kwizicelo zamashishini, imfuno yokucoceka iphantsi, kodwa kufuneka ingabikho kwizinto ezinobungozi.
IiMfuno zesicelo se-Isopropanol
Biopharmaceuticals
Kwi-biopharmaceuticals, i-isopropanol isoloko isetyenziselwa ukuxazulula iziyobisi, ukubanceda ukuba bachithe okanye bahlakazeke phantsi kweemeko ezithile. Ngenxa yokunyibilika kwayo okulungileyo kunye nokuchithwa ngokukhawuleza, i-isopropanol iluncedo kakhulu kwizifundo ze-pharmacokinetic. Ukucoceka kufuneka kufikelele ngaphezu kwe-99.99% ukukhusela ukungcola okuchaphazela umsebenzi kunye nokuzinza kweziyobisi.
Imveliso yeMichiza yoShishino
Kwimveliso yeekhemikhali zoshishino, i-isopropanol idla ngokusetyenziswa njenge-solvent kunye ne-solubilizer, ithatha inxaxheba kwiindlela ezahlukeneyo zeekhemikhali. Kule ntsimi yesicelo, imfuno yococeko iphantsi, kodwa kufuneka ingabikho kwizinto ezinobungozi ezinobungozi ukuphepha ubungozi obunokhuseleko.
Ukwenziwa koMbane
Kwimveliso ye-elektroniki, i-isopropanol isetyenziswa rhoqo njenge-solvent kunye ne-arhente yokucoca. Ngenxa yokuguquguquka okuphezulu, imboni yokuvelisa i-elektroniki ineemfuno eziphezulu kakhulu zokucoceka kwe-isopropanol ukukhusela ukungcola ekungcoliseni amacandelo e-elektroniki. I-Isopropanol ngococeko lwe-99.999% lukhetho olufanelekileyo.
Ummandla woKhuseleko lokusiNgqongileyo
Kwintsimi yokukhusela indalo, i-isopropanol isetyenziswa rhoqo njenge-solvent kunye ne-arhente yokucoca, kunye nokuthotywa okulungileyo.
