Izinyathelo zokuqapha ngezinaliti zokujova - Isigaba samanzi
\1. Uma usebenzisa umjovo owenziwe ngesandla ngomjovo, isirinji yomjovo kufanele ihlanzwe ngesisombululo sokugeza inaliti ngaphambi nangemuva komjovo. Isixazululo sokugeza inaliti ngokuvamile sikhethwa ukuba sibe yi-solvent efanayo nesixazululo sesampula. Isipetu somjovo kumele sihlanzwe ngesampula solutio...Funda kabanzi -
Umthelela wama-capillary ekuhlukaniseni kwe-HPLC
Uma uhlelo lwe-HPLC lisebenzisa indlela yokuxhuma engafanele noma uhlelo lwe-capillary olungalungile, lungase luholele ekunwebeni okuphansi kwesiqongo, kanye nokusebenza kahle kokuhlukanisa okuhle kwekholomu ye-chromatographic akukho embuzweni. Kungase kwenzeke nokuthi uma ikholomu esetshenzisiwe iba mncane, i-broa inkulu...Funda kabanzi -
Izinyathelo zokuqapha nokusetshenziswa kabi okuvamile uma usebenzisa i-Cap crimper
Elabhorethri, ukusebenzisa i-Cap crimper kuwumsebenzi ovame kakhulu, kodwa uma ingasetshenziswa kahle, kungase kubangele ukwehluleka kokuhlolwa noma izingozi. Okulandelayo kwethula izinyathelo zokuphepha nokusebenzisa kabi okuvamile uma usebenzisa i-Cap crimper. 1. Izinyathelo zokuqapha lapho usebenzisa i-Cap crimper: (1) Khetha i-r...Funda kabanzi -
