氧氮氢分析仪是快速、准确分析氧、氮、氢元素的、高性能仪器,整机采用模块化、一体化设计,即主机由可靠的脉冲电极炉、高灵敏高精度的检测系统、布局合理和气密性好的气路系统、可靠耐用的电源系统、稳定的电路系统、高校节能的水循环散热系统等六个**的硬件模块单元组成。
氧氮氢分析仪的测量原理:
测量范围非常***。分析样品时,样品被称重后放到样品端口中,然后用载气进行冲洗,防止大气(含氧气和氮气)进入到炉子系统中。
石墨坩埚在脉冲炉中脱气,以尽量减少自带的污染。经过稳定阶段后样品落入坩埚中并熔融。样品中的氧与石墨坩埚中的碳反应生成一氧化碳。氮和氢以单质的形式释放。载气和样品气体通过粉尘过滤网后再进入到氧化铜催化炉中,将一氧化碳氧化成二氧化碳。
二氧化碳进入到红外池中用于测定氧含量,被测后的气体导入化学试剂管,这时二氧化碳和水被化学试剂除去,氮元素通过热导检测池含量被测定。测量氢时,载气换为氮气,样品气体通过舒茨试剂而不是氧化铜催化剂。测氧和氮时也可采用更廉价的氩气作为载气。 山东LECO分析仪国际**的非色散红外及热导检测器 ,无移动部件,不需要手动调整。

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CO H2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。
