1. Li-reagents tsa tlhahlobo le mekhoa ea karabelo

Moemeli oa ho fokotsa le ho pata masking

Vithamine C e atisa ho sebelisoa e le ntho e fokotsang matla ka laboratoring ho fokotsa lintho tse nang le oxidizing (joalo ka elemental iodine), 'me ho fokotseha ha eona ho ka netefatsoa ka liteko tsa ho fela ha iodine.

Ka titration e rarahaneng, vithamine C e ka sebetsa e le masking agent ho felisa ho kena-kenana le li-ion tsa t?epe ha ho fumanoa.

Lipatlisiso ka Redox Reaction

Boikemisetso ba bongata ba vithamine C ka karabelo ea phokotso ea oxidation ka elemental iodine (joalo ka mokhoa oa iodometric) e sebelisoa haholo tlhahlobong ea lijo le disampole tsa baeloji.

2. Theknoloji ea ho lemoha le maemo a ts'ebeliso

Nts'etsopele ea mekhoa ea ho lemoha ka bongata

Teko ea biomedical: ho sebelisa UV spectrophotometry, high-performance liquid chromatography (HPLC), joalo-joalo, ho fumana hantle hore na vithamine C e na le serum le lisele, ho thusa ho hlahlojoa ke lingaka (joaloka scurvy).

Tlhahlobo ea lijo le litlolo: Lekola botsitso le boleng ba phepo ea vithamine C litholoana, meroho le litlolo u sebelisa mekhoa ea copper oxidation colorimetric kapa liquid chromatography.

Patlisiso ea Fisioloji ea Semela

Lekola dikahare tsa vithamine C liseleng tsa semela ho lekola phello ea khatello ea tikoloho (joalo ka komello, t?ilafalo ea t?epe e boima) lits'ebetsong tsa li-antioxidant tsa limela.

3. Ts'ebetso ea boitokiso le nts'etsopele ea tlhahiso

Ntlafatso ea ts'ebetso ea ho lokisa laboratori

Ho amohela theknoloji ea ho omisa ka leqhoa ho ntlafatsa botsitso ba li-reagents tsa vithamine C, le ho tlosa lit?ila ka ho etsa activated carbon pretreatment ho netefatsa bonnete ba ho lemoha.

Theha liforomo tse ncha tsa litekanyetso tse joalo ka li-enteric coated formulations le granules ho matlafatsa bioavailability ea vithamine C.

Tlhahiso ea lihlahisoa tse tloaelehileng le lisebelisoa tsa reagent

Lisebelisoa tse tloaelehileng tsa reagent (tse kang lisebelisoa tsa ho lemoha vithamine C) li kopantsoe le li-algorithms tsa maiketsetso tsa bohlale li nolofalletsa tlhahlobo e sebetsang ea lisampole tse kholo.

4. Netefatso ea liteko le taolo ea boleng

Netefatso ea mekhoa

Netefatsa ho nepahala ha mokhoa oa ho lemoha ka liteko tse matla tsa ho hlaphoheloa (sekhahla sa ho hlaphoheloa ke 95.6% ~ 101.0%).

Bapisa mekhoa e sa t?oaneng e kang mokhoa oa 2,4-dinitrophenylhydrazine colorimetric le mokhoa oa iodometric ho netefatsa ho t?epahala ha liphello.

Taolo ea lintlha tsa t?itiso

Ntlafatsa maemo a karabelo (joalo ka pH le mocheso) ho fokotsa t?itiso ea lintho tse ling tse fokotsang (joalo ka glutathione).

Kakaretso: Vithamine C e na le ts'ebetso ea reagent le thepa ea lipatlisiso ka laboratoring. Theknoloji ea eona ea ho lemoha, mokhoa oa ho lokisa, le lipatlisiso tsa mochine oa karabelo li fana ka t?ehetso ea bohlokoa ea tekheniki bakeng sa biomedical, mahlale a lijo le likarolo tse ling.
