氧氮氢分析仪的操作过程氧氮氢分析仪可根据的用户的要求定制。该分析仪配备两个不同灵敏度的探测器,在更多的应用中保证了准确度。操作简单而且安全。在样品称重以后,样品的重量数据通过电子界面传导至相连的电脑中,也可以在软件界面中手动输入样品的重量。样品被放置在水平放置的炉子中的低温区域。分析开始以后,炉子开始向上转动,然后样品逐渐落入加热区。通过添加载体气体氮气,氢气被扩散出来并且随载体被传导至一个高灵敏度的热传导测量池。通常一次测量的时间在3到15分钟之间。在分析的过程中设备可以显示测试信号和设备的参数,从信号的评估到结果在界面上的显示全部自动完成;而测量数据则被传导至LIMS(实验室信息管理系统)中。无需过多的保养和维护,而除尘器和净化管的维护工作也方便。新疆进口分析仪上海禹重实业有限公司致力于提供分析仪,欢迎您的来电哦!
