氧氮?dú)浞治鰞x的常見故障及解決方法:氧和氮空白值超過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,打開主電源開關(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。分析儀,就選上海禹重實(shí)業(yè)有限公司,讓您滿意,歡迎您的來(lái)電!松江分析儀
