氧氮?dú)浞治鰞x的常見(jiàn)故障及解決方法：氧和氮空白值超過(guò)20。這是由于氣流小，不能將爐子中的空氣驅(qū)趕出去。可調(diào)節(jié)氣體流量，調(diào)節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣，放一個(gè)石墨坩堝在下電極上，打開(kāi)主電源開(kāi)關(guān)，點(diǎn)擊軟件上的關(guān)爐按鈕，關(guān)閉爐子并等待10s。調(diào)節(jié)流量調(diào)節(jié)器，直到流量計(jì)a顯示為30L／h，打開(kāi)爐子。調(diào)節(jié)調(diào)節(jié)器直到流量計(jì)b顯示為50L／h，再次關(guān)閉爐子。如果以上設(shè)置不穩(wěn)定，則增加流量至100L／h，反復(fù)調(diào)節(jié)直至儀器穩(wěn)定。山東專業(yè)元素分析儀廠家直銷
