氧氮氢分析仪的原理：分析样品在惰性气流存在下于石墨坩埚中加热熔融，其中脉冲炉温度可自由设定，并通过一个非接触式的光学温度传感器进行实时监控，用于实现样品的完全分解，反应所生成的COH2和N2被带入到具有高稳定性和灵敏度的检测系统进行检测。对于CO的检测采用的是非色散性红外检测器，对于N2和H2的检测则采用热导检测器。氧氮氢分析仪的特点：快速准确分析，自动化操作；精密气体校准；CO红外检测器，高分辨率和重现性的N、H热导池检测器；同一台仪器实现熔融提取和热提取；热提取分析时间可调；可自由选择温度高达2500°C；光学温度计温度测定和控制；所有检测器自动调零/自动水平控制（ALC）；数据评估的自动优化选择范围；炉自动清洁和坩埚自动进样（可选）；外设电脑进行操作和控制；样品信息保存；所有样品数据可追踪查询；通过FTP或本地局域网进行数据传输；ON，H分析轻松切换。上海禹重实业有限公司致力于提供分析仪，欢迎您的来电！台州力可LECO分析仪
