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(shè)定，并通過一個非接觸式的光學(xué)溫度傳感器進行實時監(jiān)控，用于實現(xiàn)樣品的完全分解，反應(yīng)所生成的COH2和N2被帶入到具有高穩(wěn)定性和靈敏度的檢測系統(tǒng)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(dǎo)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(xiàn)性的N、H熱導(dǎo)池檢測器；同一臺儀器實現(xiàn)熔融提取和熱提??；熱提取分析時間可調(diào)；可自由選擇溫度高達2500°C；光學(xué)溫度計溫度測定和控制；所有檢測器自動調(diào)零/自動水平控制（ALC）；數(shù)據(jù)評估的自動優(yōu)化選擇范圍；爐自動清潔和坩堝自動進樣（可選）；外設(shè)電腦進行操作和控制；樣品信息保存；所有樣品數(shù)據(jù)可追蹤查詢；通過FTP或本地局域網(wǎng)進行數(shù)據(jù)傳輸；ON，H分析輕松切換。上海禹重實業(yè)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
