液相色谱仪恒流泵故障检修流程!

发布时间:2017/02/23 点击量:


新英体育 高压恒流泵是一台由微电脑控制的往复式双柱塞并联泵,具有操作方便、流速稳定、压力脉动小、故障率低的特点,能很好地起到高效液相色谱系统中输液单元的作用。在进行色谱仪分析实验过程中,流动相溶液中杂质残留会对泵造成损害。以下简要分析液相色谱仪恒流泵故障检修方法及流程。


1.将泵的流动相替换成纯化水,将盛有纯化水的储液瓶置于高位而形成位压差。拧开卸下流动相输入管的螺丝,观察从流动相输入管口流出的纯化水的流速;如果流的纯化水很顺畅,说明过滤头没问题。如果流的纯化水流速很慢或者是一滴一滴向下滴,说明过滤头需要清洗(采用超声波清洗机处理)。
