Incazelo Yomkhiqizo:
Igama lesayensi lamafutha kagesi amhlophe yi-n-heptane, ngoba i-solubility ephezulu yamafutha kanye nokuguquguquka okukhulu, futhi inekhono eliqinile lokuqeda ukungcola, livame ukusetshenziswa njenge-ejenti yokuhlanza embonini, futhi iyikhemikhali esetshenziswa kabanzi ku-hardware, izimboni zikagesi, zokunyathelisa nezokwenza izicathulo.
Isicelo somkhiqizo:
1.Isetshenziswa njenge-reagent yokuhlaziya, indinganiso yokuhlola yokuqhuma kwenjini kaphethiloli, inkomba yokuhlaziywa kwe-chromatographic, i-solvent. Umkhiqizo ungashukumisa ipheshana lokuphefumula, futhi unomphumela we-anesthetic ekugxilweni okuphezulu. Iyakwazi ukuvutha, ukuhlushwa okulinganiselwe kokwenza ingxube yeziqhumane emoyeni ngu-1.0-6.0% (v/v).
I-2.Ingasetshenziswa njenge-solvent yokukhipha amafutha ezilwane nezitshalo namafutha, usimende wenjoloba owomisa ngokushesha. I-solvent yemboni yenjoloba. Ibuye isetshenziswe njengokuhlanza i-solvent kupende, i-varnish, uyinki owomisa ngokushesha kanye nemboni yokunyathelisa. Umkhiqizo ohlanzekile usetshenziswa njengophethiloli ojwayelekile wokunquma inombolo ye-octane kaphethiloli.
3.Isetshenziswa njengesithako esijwayelekile nesincibilikisa ukunqunywa kwenombolo ye-octane, kanye nokuhlanganiswa kwezinto eziphilayo kanye nokulungiselela ama-reagents okuhlola.
Amanothi Okugcina Umkhiqizo:
1.Gcina endaweni epholile, nengena umoya.
2. Gcina kude nomlilo kanye nomthombo wokushisa.
3.Izinga lokushisa lokugcina akufanele lidlule ku-37°C.
4.Gcina isitsha sivaliwe.
5.Kufanele igcinwe ngokuhlukana nama-oxidising agents, futhi akufanele neze ixutshwe.
6.Sebenzisa izibani ezingaqhumi kanye nezindawo zokungenisa umoya.
7.Vimbela ukusetshenziswa kwemishini namathuluzi alula ukwenza izinhlansi.
I-8.Indawo yokugcina kufanele ifakwe imishini yokwelapha izimo eziphuthumayo ezivuzayo kanye nezinto zokukhosela ezifanele.
