索氏提取器的(de)(de)(de)使(shi)用方(fang)法(fa)從固(gu)(gu)(gu)體物(wu)(wu)質中(zhong)(zhong)萃(cui)(cui)(cui)(cui)取(qu)(qu)化合物(wu)(wu)的(de)(de)(de)一種方(fang)法(fa)是,用溶(rong)(rong)劑(ji)(ji)將(jiang)固(gu)(gu)(gu)體長(chang)期(qi)浸(jin)潤而將(jiang)所(suo)需要的(de)(de)(de)物(wu)(wu)質浸(jin)出(chu)(chu)來,即長(chang)期(qi)浸(jin)出(chu)(chu)法(fa)。此法(fa)花費時(shi)間長(chang).溶(rong)(rong)劑(ji)(ji)用量大(da)、效(xiao)率不高。在實驗室多采用脂肪(fang)提(ti)取(qu)(qu)器(qi)(索氏(shi)提(ti)取(qu)(qu)器(qi))來提(ti)取(qu)(qu)、脂肪(fang)提(ti)取(qu)(qu)器(qi)就是利(li)用溶(rong)(rong)劑(ji)(ji)回(hui)流及虹吸原理,使(shi)固(gu)(gu)(gu)體物(wu)(wu)質連續(xu)不斷地被純溶(rong)(rong)劑(ji)(ji)萃(cui)(cui)(cui)(cui)取(qu)(qu),既節約溶(rong)(rong)利(li)萃(cui)(cui)(cui)(cui)取(qu)(qu)效(xiao)率又高。萃(cui)(cui)(cui)(cui)取(qu)(qu)前先將(jiang)固(gu)(gu)(gu)體物(wu)(wu)質研碎,以(yi)增加固(gu)(gu)(gu)液接(jie)觸(chu)的(de)(de)(de)面(mian)積。然后將(jiang)固(gu)(gu)(gu)體物(wu)(wu)質放(fang)在濾紙套1內(nei),置于提(ti)取(qu)(qu)器(qi)2中(zhong)(zhong),提(ti)取(qu)(qu)器(qi)的(de)(de)(de)下端(duan)勺(shao)盛有溶(rong)(rong)劑(ji)(ji)的(de)(de)(de)圓底燒(shao)瓶相連,上面(mian)接(jie)回(hui)流冷(leng)凝(ning)管(guan)。加熱園底燒(shao)瓶,使(shi)溶(rong)(rong)劑(ji)(ji)沸(fei)騰,蒸(zheng)氣通過提(ti)取(qu)(qu)器(qi)的(de)(de)(de)支(zhi)管(guan)3上升(sheng),被冷(leng)凝(ning)后滴入提(ti)取(qu)(qu)器(qi)中(zhong)(zhong),溶(rong)(rong)劑(ji)(ji)和固(gu)(gu)(gu)體接(jie)觸(chu)進行萃(cui)(cui)(cui)(cui)取(qu)(qu),當溶(rong)(rong)劑(ji)(ji)面(mian)超(chao)過虹吸管(guan)4的(de)(de)(de)zui高處時(shi),含有萃(cui)(cui)(cui)(cui)取(qu)(qu)物(wu)(wu)的(de)(de)(de)溶(rong)(rong)劑(ji)(ji)虹吸回(hui)燒(shao)瓶,因而萃(cui)(cui)(cui)(cui)取(qu)(qu)出(chu)(chu)一部分物(wu)(wu)質,如此重復(fu),使(shi)固(gu)(gu)(gu)體物(wu)(wu)質不斷為(wei)純的(de)(de)(de)溶(rong)(rong)劑(ji)(ji)所(suo)蘋取(qu)(qu)、將(jiang)萃(cui)(cui)(cui)(cui)取(qu)(qu)出(chu)(chu)的(de)(de)(de)物(wu)(wu)質富集在燒(shao)瓶中(zhong)(zhong)。
液—固萃取(qu)(qu)是利(li)(li)用(yong)(yong)溶(rong)劑(ji)(ji)對(dui)固體(ti)混合(he)物(wu)中(zhong)(zhong)所(suo)需成分的(de)(de)(de)溶(rong)解度(du)大(da),對(dui)雜質(zhi)的(de)(de)(de)溶(rong)解度(du)小來達(da)到提(ti)取(qu)(qu)分離的(de)(de)(de)目的(de)(de)(de).一種方(fang)(fang)法(fa)(fa)是把固體(ti)物(wu)質(zhi)放于溶(rong)劑(ji)(ji)中(zhong)(zhong)長期(qi)浸泡(pao)而達(da)到萃取(qu)(qu)的(de)(de)(de)目的(de)(de)(de),但是這種方(fang)(fang)法(fa)(fa)時間長,消耗溶(rong)劑(ji)(ji),萃取(qu)(qu)效率也(ye)不高(gao).另一種是采用(yong)(yong)索氏提(ti)取(qu)(qu)器的(de)(de)(de)方(fang)(fang)法(fa)(fa),它是利(li)(li)用(yong)(yong)溶(rong)劑(ji)(ji)的(de)(de)(de)回流(liu)和虹(hong)(hong)吸原理,對(dui)固體(ti)混合(he)物(wu)中(zhong)(zhong)所(suo)需成分進行連續(xu)提(ti)取(qu)(qu).當(dang)提(ti)取(qu)(qu)筒中(zhong)(zhong)回流(liu)下的(de)(de)(de)溶(rong)劑(ji)(ji)的(de)(de)(de)液面超過索氏提(ti)取(qu)(qu)器的(de)(de)(de)虹(hong)(hong)吸管時,提(ti)取(qu)(qu)筒中(zhong)(zhong)的(de)(de)(de)溶(rong)劑(ji)(ji)流(liu)回圓底燒瓶內,即發生虹(hong)(hong)吸.隨溫度(du)升高(gao),再次回流(liu)開始,每(mei)次虹(hong)(hong)吸前,固體(ti)物(wu)質(zhi)都能被純的(de)(de)(de)熱溶(rong)劑(ji)(ji)所(suo)萃取(qu)(qu),溶(rong)劑(ji)(ji)反復利(li)(li)用(yong)(yong),縮短了提(ti)取(qu)(qu)時間,所(suo)以萃取(qu)(qu)效率較高(gao)。
