四、CQ-1型500ml索氏提取(萃取)器使用方法：

1、 萃取(qu)前應先將固體物質(zhi)研磨細，以增加(jia)液(ye)體浸溶(rong)(rong)(rong)的面積。然后(hou)將固體物質(zhi)放在濾紙套內，放置(zhi)于(yu)萃取(qu)室(shi)中。當(dang)溶(rong)(rong)(rong)劑(ji)(ji)(ji)加(jia)熱沸騰后(hou)，蒸汽(qi)通過導氣管上升(sheng)，被(bei)冷凝為液(ye)體滴入提取(qu)器中。當(dang)液(ye)面超過虹吸(xi)(xi)管最高處時(shi)，即發生虹吸(xi)(xi)現(xian)象，溶(rong)(rong)(rong)劑(ji)(ji)(ji)回(hui)流入燒瓶，因(yin)此可(ke)萃取(qu)出溶(rong)(rong)(rong)于(yu)溶(rong)(rong)(rong)劑(ji)(ji)(ji)的部分物質(zhi)。就這樣利用溶(rong)(rong)(rong)劑(ji)(ji)(ji)回(hui)流和虹吸(xi)(xi)作用，使(shi)固體中的可(ke)溶(rong)(rong)(rong)物富集到燒瓶內。

2、 提(ti)取(qu)(qu)時，將待測樣(yang)(yang)品(pin)包(bao)在脫脂濾紙(zhi)包(bao)內(nei)，放入(ru)(ru)萃(cui)(cui)(cui)取(qu)(qu)管(guan)內(nei)。萃(cui)(cui)(cui)取(qu)(qu)瓶內(nei)加入(ru)(ru)石油醚，加熱(re)萃(cui)(cui)(cui)取(qu)(qu)瓶，石油醚氣化，由連接(jie)管(guan)上升進入(ru)(ru)冷凝(ning)(ning)器，凝(ning)(ning)成液(ye)體滴入(ru)(ru)萃(cui)(cui)(cui)取(qu)(qu)管(guan)內(nei)。浸提(ti)樣(yang)(yang)品(pin)中(zhong)的(de)脂類物(wu)質。待萃(cui)(cui)(cui)取(qu)(qu)管(guan)內(nei)石油醚液(ye)面達到(dao)一定高度，溶有樣(yang)(yang)品(pin) 的(de)石油醚經虹吸管(guan)流(liu)入(ru)(ru)提(ti)取(qu)(qu)瓶。流(liu)入(ru)(ru)萃(cui)(cui)(cui)取(qu)(qu)瓶內(nei)的(de)石油醚繼續被(bei)加熱(re)氣化、上升、冷凝(ning)(ning)，滴入(ru)(ru)提(ti)取(qu)(qu)管(guan)內(nei)，如(ru)此(ci)循環往復，直到(dao)抽提(ti)為止。

3、 把(ba)濾(lv)紙(zhi)做(zuo)成與(yu)萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)大小相(xiang)應(ying)的(de)(de)濾(lv)紙(zhi)筒(tong)，然后把(ba)需要提(ti)(ti)取(qu)(qu)(qu)(qu)的(de)(de)樣品放在(zai)濾(lv)紙(zhi)筒(tong)內(nei)，裝入萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)，注意(yi)濾(lv)紙(zhi)筒(tong)既要緊貼器(qi)(qi)壁，又要方(fang)便取(qu)(qu)(qu)(qu)放（濾(lv)紙(zhi)筒(tong)上可以套(tao)一(yi)(yi)圈棉線，方(fang)便提(ti)(ti)取(qu)(qu)(qu)(qu)完成后取(qu)(qu)(qu)(qu)出(chu)(chu)(chu)濾(lv)紙(zhi)筒(tong)）。被(bei)(bei)提(ti)(ti)取(qu)(qu)(qu)(qu)物(wu)(wu)高(gao)度不(bu)能超過虹吸(xi)(xi)(xi)(xi)管(guan)(guan)，否則被(bei)(bei)提(ti)(ti)取(qu)(qu)(qu)(qu)物(wu)(wu)不(bu)能被(bei)(bei)溶(rong)(rong)劑(ji)(ji)充分浸(jin)泡，影響提(ti)(ti)取(qu)(qu)(qu)(qu)效果，被(bei)(bei)提(ti)(ti)取(qu)(qu)(qu)(qu)物(wu)(wu)亦不(bu)能漏出(chu)(chu)(chu)濾(lv)紙(zhi)筒(tong)，以免堵塞虹吸(xi)(xi)(xi)(xi)管(guan)(guan)，如果試(shi)樣較輕，可以用脫脂棉壓住試(shi)樣。萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)的(de)(de)下端(duan)與(yu)盛有溶(rong)(rong)劑(ji)(ji)的(de)(de)萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)瓶(ping)(ping)相(xiang)連(lian)，上面(mian)接回流冷(leng)凝(ning)管(guan)(guan)。用加(jia)熱(re)套(tao)加(jia)熱(re)萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)瓶(ping)(ping)，使溶(rong)(rong)劑(ji)(ji)沸騰，蒸汽通過萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)的(de)(de)支管(guan)(guan)上升(sheng)，被(bei)(bei)冷(leng)凝(ning)后滴(di)入萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)中(zhong)(zhong)，當溶(rong)(rong)劑(ji)(ji)面(mian)超過虹吸(xi)(xi)(xi)(xi)管(guan)(guan)的(de)(de)最(zui)高(gao)處時，含有萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)物(wu)(wu)的(de)(de)溶(rong)(rong)劑(ji)(ji)虹吸(xi)(xi)(xi)(xi)回萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)器(qi)(qi)，因而萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)出(chu)(chu)(chu)一(yi)(yi)部分物(wu)(wu)質(zhi)(zhi)，如此重復，使固體物(wu)(wu)質(zhi)(zhi)不(bu)斷為純的(de)(de)溶(rong)(rong)劑(ji)(ji)所萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)、將萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)出(chu)(chu)(chu)的(de)(de)物(wu)(wu)質(zhi)(zhi)富(fu)集在(zai)萃(cui)(cui)(cui)(cui)(cui)(cui)(cui)取(qu)(qu)(qu)(qu)瓶(ping)(ping)中(zhong)(zhong)。

4、在萃取用(yong)的(de)燒瓶中(zhong)加(jia)入萃取溶(rong)劑和沸石（沒有沸石可以用(yong)玻璃珠(zhu)或碎(sui)瓷片），目的(de)就是防(fang)止(zhi)暴(bao)沸。

5、 具(ju)體(ti)的回流時間是(shi)不一樣的，有(you)的是(shi)提(ti)(ti)取至提(ti)(ti)取液無色。總之就是(shi)要提(ti)(ti)取。停(ting)止(zhi)加熱，移去(qu)加熱套，冷(leng)卻(que)提(ti)(ti)取液。拆(chai)除索氏萃取器(qi)，安裝冷(leng)凝管進(jin)行(xing)蒸餾。

五、加熱套注意事

1、由于玻璃纖維表面涂(tu)有(you)油脂，使用時(shi)要(yao)緩慢升溫，見生白煙(yan)后關(guan)閉電(dian)源，煙(yan)散后在通電(dian)升溫，反復(fu)幾次，直到通電(dian)無(wu)煙(yan)后，即可正式使用。

2、電(dian)熱套內不能進入易(yi)燃、易(yi)爆、具有腐蝕(shi)性液體(ti)或氣體(ti)。電(dian)熱套的相對工作環境(jing)濕度(du)不超過85%。

3、本產品一定(ding)要(yao)接地，存放時要(yao)干(gan)燥(zao)、切勿受潮。如(ru)有(you)潮濕，使(shi)用時應注意(yi)有(you)感(gan)應電，不要(yao)用手觸摸，待其(qi)干(gan)燥(zao)后便(bian)可恢復其(qi)良好的絕緣性能。
