氧氮氫分析儀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趕出去??烧{節(jié)氣體流量,調節(jié)載氣壓力在0.2~0.4MPa。接通儀器載氣,放一個石墨坩堝在下電極上,打開主電源開關,點擊軟件上的關爐按鈕,關閉爐子并等待10s。調節(jié)流量調節(jié)器,直到流量計a顯示為30L/h,打開爐子。調節(jié)調節(jié)器直到流量計b顯示為50L/h,再次關閉爐子。如果以上設置不穩(wěn)定,則增加流量至100L/h,反復調節(jié)直至儀器穩(wěn)定。專業(yè)元素分析儀供應商上海禹重實業(yè)有限公司為您提供分析儀,有想法的不要錯過哦!
