Isisetshenziswa Selabhorethri esisekelwe Kumgomo We-Soxhlet Extraction

UFranz Von Soxhlet, ngemuva kokushicilela amaphepha akhe mayelana nezakhiwo zobisi ngo-1873 kanye nendlela yokukhiqizwa kwebhotela ngo-1876, eyanyatheliswa ngo-1879 enye yezimpumelelo zakhe ezibaluleke kakhulu emkhakheni wezobuchwepheshe be-lipid: Wasungula ithuluzi elisha lokukhipha. amafutha asuka obisini, kamuva asetshenziswa kabanzi emhlabeni wonke ukukhipha amafutha ezintweni eziphilayo:I-Soxhlet extractor

I-Soxhlet extractorinqubo yokunquma isampula:

(1) Faka i-cartridge yephepha lesihlungi kusilinda sokukhipha i-Soxhlet extractor, xhuma inkomishi yamafutha eyomisiwe esisindweni esingaguquki, engeza i-ether noma i-petroleum ether kusukela ekugcineni okuphezulu kweshubhu le-condensate yesikhi kuya ku-2/3 we umthamo webhodlela, udlulise amanzi e-condensate, cwilisa ibhodlela elingaphansi emanzini okugeza ukuze ushise, futhi ngobumnene uxhume ibhola elincane likakotini elimunca emlonyeni ongaphezulu weshubhu le-condensate.
(2) Ukulawula izinga lokushisa lokukhipha: ngokuya ngokulungiselelwa kokuhlolwa okuthile.
(3) Ukulawula isikhathi sokukhipha: isikhathi sokukhipha sincike kumafutha angcolile wesampula, imitha yamafutha ngokuvamile ikhishwa 1-1.5h, isampula iqukethe ukukhishwa kwamafutha kuqedile, ungasebenzisa iphepha lokuhlunga ukuze ugwebe, kusukela ekukhishweni. ithubhu ukumunca inani elincane le-ether bese uphonsa ephepheni lokuhlunga elihlanzekile, ngemva kokuba i-ether isomile, iphepha lokuhlunga alishiyi noma yimaphi amafutha kulo kusho ukuthi likhishwe ngokuphelele.
(4) Ukukhipha kuqediwe. Ngemva kokuba ukukhishwa kuqediwe, i-ether ishunqiselwa ku-tube yokukhipha, futhi ithubhu yokukhipha isusiwe ngaphambi kokuba izinga le-ether liquid lifinyelele endaweni ephakeme kakhulu ye-siphon.

DRK-SOX316 fat analyzer kusekelwe esimisweni sokukhishwa kwe-Soxhlet, ngokusho kwe-GB/T 14772-2008 design ejwayelekile ye-othomathikhi ye-crude fat analyzer, iyithuluzi elifanele lokunqunywa kwamafutha ekudleni, emafutheni, ekudleni nakwezinye izimboni, kodwa futhi kufanelekile ukukhishwa noma ukunqunywa kwezinhlanganisela ezincibilikayo emikhakheni ehlukene njengezolimo, imvelo kanye nezimboni.

Ukulinganisa ububanzi obungu-0.1-100%, kunganquma okuqukethwe kwamafutha angcolile ekudleni, okuphakelayo, okusanhlamvu, imbewu namanye amasampula;
Ukukhishwa kwamafutha ku-sludge;
Ukukhishwa kwezingxube ze-semi-volatile organic emhlabathini, izibulala-zinambuzane, ama-herbicides, njll.;
Khipha i-plasticizer kumapulasitiki, i-rosin ephepheni nasepuleti lephepha, amafutha esikhumba, njll.;
Ukwehliswa kwangaphambili kokugaya kwamasampula aqinile ngesigaba segesi kanye ne-chromatography ewuketshezi;
Okunye ukuhlola kokukhipha izinhlanganisela ezincibilikayo noma ukunquma amafutha aluhlaza.
