Izixhobo zeLabhoratri ezisekelwe kuMgaqo we-Soxhlet Extraction

UFranz Von Soxhlet, emva kokupapasha amaphepha akhe malunga neempawu zomzimba zobisi ngo-1873 kunye nendlela yokuveliswa kwebhotolo ngo-1876, eyapapashwa ngo-1879 enye yezona mpumelelo zakhe zibalulekileyo kwi-teknoloji ye-lipid: Wayila isixhobo esitsha sokukhupha. amanqatha kubisi, awathi kamva asetyenziswa ngokubanzi kwihlabathi liphela ukukhupha amanqatha kwizinto zebhayoloji:Soxhlet extractor

Soxhlet extractorinkqubo yokugqiba isampulu:

(1) Beka i-cartridge yephepha lokucoca kwi-cylinder yokukhutshwa kwe-Soxhlet extractor, qhagamshela indebe enamafutha eyomisiweyo kubunzima obuqhubekayo, yongeza i-ether okanye i-petroleum ether ukusuka ekupheleni komntla we-condensate tube ye-extractor ukuya kwi-2/3 ye-extractor. umthamo webhotile, udlulise amanzi e-condensate, ucwilise ibhotile ephantsi kwibhafu yamanzi ukutshisa, kwaye ngobunono udibanise ibhola encinci yekotoni efunxayo emlonyeni ophezulu wetyhubhu ye-condensate.
(2) Ukulawula ubushushu bokukhutshwa: ngokuhambelana nesetingi yovavanyo oluthile.
(3) Ulawulo lwexesha lokukhutshwa: ixesha lokukhupha lixhomekeke kumxholo wamafutha akrwada kwisampulu, imitha ye-fat ikhutshwa ngokubanzi i-1-1.5h, isampuli iqulethe i-fat extraction igqityiwe, ungasebenzisa iphepha lokucoca ukugweba ngokukhawuleza, ukusuka kwi-extraction. ityhubhu ukufunxa inani elincinci le-ether kunye nokulahla kwiphepha lokucoca elicocekileyo, emva kokuba i-ether yomile, iphepha lokucoca alishiyi nayiphi na igrisi kuyo ithetha ukuba ikhutshwe ngokupheleleyo.
(4) Ukukhutshwa kugqityiwe. Emva kokuba ukukhutshwa kugqityiwe, i-ether ifakwe kwi-tube yokukhupha, kwaye ityhubhu yokukhutshwa isuswe ngaphambi kokuba i-ether liquid level ifike kwindawo ephezulu ye-siphon.

DRK-SOX316 i-fat analyzer isekelwe kumgaqo we-Soxhlet extraction, ngokomgangatho wesizwe we-GB/T 14772-2008 uyilo lwe-automatic crude fat analyzer, sisixhobo esifanelekileyo sokumisela amanqatha ekudleni, kwi-oyile, kwisondlo nakwamanye amashishini, kodwa kwakhona kufanelekile ukukhutshwa okanye ukumiselwa kweekhompawundi ezinyibilikayo kwiinkalo ezahlukeneyo ezifana nezolimo, okusingqongileyo kunye noshishino.

Umlinganiselo wokulinganisa i-0.1-100%, unokugqiba umxholo wamafutha akrwada ekutyeni, ukutya, iinkozo, imbewu kunye nezinye iisampuli;
Ukukhutshwa kwegrisi kwi-sludge;
Ukukhutshwa kweekhompawundi ze-semi-volatile eziphilayo emhlabeni, izitshabalalisi, imichiza yokutshabalalisa ukhula, njl.;
Khipha i-plasticizer kwiiplastiki, i-rosin kwiphepha kunye neplate yephepha, igrisi ngesikhumba, njl.;
Ukwetyisa kwangaphambi kokunyangwa kweesampulu eziqinileyo ngesigaba segesi kunye nekhromatografi yolwelo;
Eminye imifuniselo yokukhupha iikhompawundi ezinyibilikayo okanye ukufumanisa amafutha akrwada.
