氧氮氫分析儀的原理：分析樣品在惰性氣流存在下于石墨坩堝中加熱熔融，其中脈沖爐溫度可自由設定，并通過一個非接觸式的光學溫度傳感器進行實時監控，用于實現樣品的完全分解，反應所生成的COH2和N2被帶入到具有高穩定性和靈敏度的檢測系統進行檢測。對于CO的檢測采用的是非色散性紅外檢測器，對于N2和H2的檢測則采用熱導檢測器。氧氮氫分析儀的特點：快速準確分析，自動化操作；精密氣體校準；CO紅外檢測器，高分辨率和重現性的N、H熱導池檢測器；同一臺儀器實現熔融提取和熱提取；熱提取分析時間可調；可自由選擇溫度高達2500°C；光學溫度計溫度測定和控制；所有檢測器自動調零/自動水平控制（ALC）；數據評估的自動優化選擇范圍；爐自動清潔和坩堝自動進樣（可選）；外設電腦進行操作和控制；樣品信息保存；所有樣品數據可追蹤查詢；通過FTP或本地局域網進行數據傳輸；ON，H分析輕松切換。上海禹重實業有限公司致力于提供分析儀，歡迎您的來電！臺州力可LECO分析儀
