氣相色譜儀空氣發生器  實驗室使用(yong)的空氣(qi)要求嚴格，為能確保實驗正常(chang)進行，需要對日常(chang)生(sheng)(sheng)活中我們接(jie)觸的空氣(qi)進行處(chu)理，這樣才能被使用(yong)，從而“誕(dan)生(sheng)(sheng)"了(le)空氣(qi)發生(sheng)(sheng)器!空氣(qi)發生(sheng)(sheng)器代(dai)替了(le)原來(lai)傳(chuan)統使用(yong)的高(gao)壓空氣(qi)瓶。

　　空氣發生(sheng)器(qi)的結(jie)構原(yuan)理，空氣發生(sheng)器(qi)一般是(shi)由空氣泵(beng)/壓縮機、穩壓系統、壓力(li)控制系統、凈化(hua)系統和顯示系統組成。　

　在氣(qi)(qi)相色譜的(de)使用(yong)(yong)(yong)(yong)過程中，空(kong)氣(qi)(qi)的(de)用(yong)(yong)(yong)(yong)途有(you)(you)多種：一(yi)方面，FID、FPD和NPD都(dou)需要(yao)使用(yong)(yong)(yong)(yong)空(kong)氣(qi)(qi)作為助燃氣(qi)(qi)；另(ling)外，當(dang)氣(qi)(qi)相色譜儀安裝有(you)(you)自動(dong)六通閥(fa)等(deng)裝置(zhi)時候，可以使用(yong)(yong)(yong)(yong)空(kong)氣(qi)(qi)作為驅(qu)動(dong)切(qie)換裝置(zhi)進(jin)行切(qie)換的(de)驅(qu)動(dong)氣(qi)(qi)；此外，當(dang)使用(yong)(yong)(yong)(yong)FID等(deng)檢測器進(jin)行檢測時，一(yi)些(xie)研究人員使用(yong)(yong)(yong)(yong)空(kong)氣(qi)(qi)作為尾吹(chui)氣(qi)(qi)，具有(you)(you)一(yi)些(xie)出人意外的(de)結果。

　　因為氣(qi)(qi)相(xiang)色(se)譜(pu)使(shi)(shi)用(yong)(yong)的(de)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)流(liu)量(liang)較大，單臺(tai)FID使(shi)(shi)用(yong)(yong)的(de)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)流(liu)量(liang)可以達到300mL/min左右，因此(ci)并不能(neng)通過(guo)(guo)使(shi)(shi)用(yong)(yong)大氣(qi)(qi)中(zhong)的(de)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)來(lai)滿(man)足儀(yi)器(qi)(qi)的(de)需求。常用(yong)(yong)的(de)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)供(gong)(gong)給方式包括(kuo)使(shi)(shi)用(yong)(yong)鋼(gang)(gang)瓶空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)和使(shi)(shi)用(yong)(yong)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)壓(ya)(ya)縮(suo)機(ji)(ji)(ji)(ji)/空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)來(lai)提供(gong)(gong)。鋼(gang)(gang)瓶空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)需要(yao)向氣(qi)(qi)體(ti)供(gong)(gong)應(ying)商購(gou)買，空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)/壓(ya)(ya)縮(suo)機(ji)(ji)(ji)(ji)的(de)種(zhong)類(lei)、原理和結構多(duo)種(zhong)多(duo)樣，難以一一說明，本文主要(yao)談及(ji)可置于(yu)實驗室內的(de)小型無油空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)。（請注意是使(shi)(shi)用(yong)(yong)無油空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)）從(cong)名稱上而(er)言，無論稱之為空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)、空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)源、空(kong)(kong)(kong)(kong)(kong)壓(ya)(ya)機(ji)(ji)(ji)(ji)或者空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)壓(ya)(ya)縮(suo)機(ji)(ji)(ji)(ji)，其本質類(lei)似，都(dou)是通過(guo)(guo)氣(qi)(qi)體(ti)壓(ya)(ya)縮(suo)機(ji)(ji)(ji)(ji)來(lai)提供(gong)(gong)達到一定壓(ya)(ya)力的(de)氣(qi)(qi)體(ti)。介于(yu)實驗室氣(qi)(qi)相(xiang)色(se)譜(pu)儀(yi)使(shi)(shi)用(yong)(yong)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)的(de)要(yao)求，空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)發(fa)(fa)生(sheng)器(qi)(qi)會在壓(ya)(ya)縮(suo)機(ji)(ji)(ji)(ji)后(hou)安(an)裝儲(chu)氣(qi)(qi)罐(guan)、凈化(hua)裝置等，從(cong)而(er)使(shi)(shi)提供(gong)(gong)的(de)空(kong)(kong)(kong)(kong)(kong)氣(qi)(qi)達到使(shi)(shi)用(yong)(yong)的(de)要(yao)求。
