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。分析仪,就选上海禹重实业有限公司,用户的信赖之选,欢迎新老客户来电!
