HK-8100電感耦合等離子體的(de)形成(cheng)(cheng)就是工作氣體的(de)電離過程(cheng)。為了(le)形成(cheng)(cheng)穩定的(de)   HK-8100電感耦合等(deng)離子(zi)體(ti)炬焰需要四個條(tiao)件：   高頻高強度(du)的電磁場  ，工作氣體 ，維持(chi)氣(qi)體穩定放電(dian)的石英矩管(guan) ，電子離子源     
矩管(guan)(guan)是(shi)由直徑20mm的(de)三重同(tong)心(xin)石(shi)英(ying)管(guan)(guan)構成。石(shi)英(ying)外管(guan)(guan)和中間(jian)管(guan)(guan)之間(jian)同(tong)10~20L/min的(de)氬氣(qi)，其(qi)作(zuo)(zuo)用是(shi)作(zuo)(zuo)為工(gong)作(zuo)(zuo)氣(qi)體形(xing)成等(deng)離(li)子體并冷卻石(shi)英(ying)矩管(guan)(guan)，稱(cheng)為等(deng)離(li)子體氣(qi)或冷卻氣(qi)。中間(jian)管(guan)(guan)和中心(xin)管(guan)(guan)通(tong)入(ru)05~1.5L/min氬氣(qi)，稱(cheng)為輔(fu)助氣(qi)，用以(yi)輔(fu)助等(deng)離(li)子體的(de)形(xing)成。中心(xin)管(guan)(guan)用于導入(ru)試樣氣(qi)溶膠(jiao)。石(shi)英(ying)矩管(guan)(guan)外套(tao)有高頻感應線圈，感應圈一般為2~4圈空心(xin)銅管(guan)(guan)。
         形成 HK-8100電感耦(ou)合等離子(zi)體焰炬通稱(cheng)為(wei)點火。點火分(fen)三步：*步是(shi)(shi)向外(wai)管及中管通入等離(li)子體(ti)(ti)和輔助氣(qi)(qi)，此時(shi)中心管不(bu)通氣(qi)(qi)體(ti)(ti)，在矩管中建立氬(ya)氣(qi)(qi)氣(qi)(qi)氛；第二部(bu)向感(gan)(gan)(gan)應線圈接入高(gao)(gao)頻電(dian)(dian)(dian)(dian)(dian)(dian)源，一般頻率為(wei)27~40MHz，電(dian)(dian)(dian)(dian)(dian)(dian)源功率為(wei)1~1.5KW，此時(shi)線圈內(nei)有高(gao)(gao)頻電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)及由(you)它(ta)(ta)產生(sheng)(sheng)的(de)高(gao)(gao)頻電(dian)(dian)(dian)(dian)(dian)(dian)磁場。由(you)于(yu)在室(shi)溫(wen)下干燥的(de)氬(ya)氣(qi)(qi)并不(bu)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)，不(bu)會(hui)在氬(ya)氣(qi)(qi)中產生(sheng)(sheng)感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，必須用(yong)其他(ta)方(fang)法使氬(ya)氣(qi)(qi)局(ju)部(bu)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)成(cheng)為(wei)導(dao)(dao)體(ti)(ti)。高(gao)(gao)頻電(dian)(dian)(dian)(dian)(dian)(dian)磁場才能使它(ta)(ta)進(jin)一步電(dian)(dian)(dian)(dian)(dian)(dian)離(li)形成(cheng)等離(li)子體(ti)(ti)。使氬(ya)氣(qi)(qi)部(bu)分(fen)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)的(de)方(fang)法有兩種(zhong)，一種(zhong)是(shi)(shi)石墨(mo)棒(bang)加熱(re)法，目前多用(yong)能產生(sheng)(sheng)放電(dian)(dian)(dian)(dian)(dian)(dian)的(de)高(gao)(gao)壓Tesla線圈，在管內(nei)氬(ya)氣(qi)(qi)流(liu)中形成(cheng)放電(dian)(dian)(dian)(dian)(dian)(dian)，使氬(ya)氣(qi)(qi)局(ju)部(bu)電(dian)(dian)(dian)(dian)(dian)(dian)離(li)為(wei)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)體(ti)(ti)，并進(jin)而產生(sheng)(sheng)感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)。感(gan)(gan)(gan)應電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)加熱(re)氣(qi)(qi)體(ti)(ti)，形成(cheng)火炬狀 HK-8100電(dian)感耦合等離子體炬焰(yan)。
