氧氮氢分析仪的常见故障及解决方法供电正常、通讯正常,点击确认键后分析仪不工作。这是没有水流,炉子温度太高或仪器通道电压不正常。如没有水流,炉子温度太高这些信息会显示在显示器画面上,但没有信息显示说明这两项正常。接下来检查仪器通道零位电压,如果比±3V高出1V以上,可能是因为气瓶空了,或者是空气进入到分析仪中。检查并更换化学试剂,如果有空气进入热导池里,热导池的电压就会<-6V,此时打开右面的门,堵住炉子气体进口,10s后,热导池电压值必然升高。经过逐一排查,**终确认碱石棉有问题,更换后仪器正常。上海禹重实业有限公司为您提供分析仪,有需要可以联系我司哦!
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,有需求可以来电咨询!安徽专业分析仪采购
