一、气相色谱仪检修的一般知识当你在操作气相色谱仪的时候,一旦仪器发生了故障,怎么办呢?本文想以SP-2305型气相色谱仪为例,谈谈检修这类仪器的一些经验体会。对于该仪器的检修,应注意以下两点: 第一,对有故障的仪器,先作表观检查,后作电气检查。仪器的故障一般可分为两类,一类比较简单,另一类比较复杂。简单的故障,从表面进行观察就容易发现,例如:电子管的灯丝不亮、零件断裂或互碰、变压器冒烟、脱焊断线等。比较复杂的故障,则需要根据仪器的工作原理,借助简易的测试仪表,配合仪器面板上 First, the general knowledge of gas chromatography repair When you operate the gas chromatograph, once the instrument fails, how to do it? This article would like to SP-2305 gas chromatograph, for example, to talk about the maintenance of some of these instruments Experience experience. For the maintenance of the instrument, should pay attention to the following two points: First, the faulty instrument, for the first visual inspection, after the electrical test. Instrument failure generally can be divided into two categories, one is relatively simple, the other is more complicated. Simple fault, easy to observe from the surface to find, for example: the tube filament is not bright, parts break or touch each other, transformer smoke, off the wire and so on. More complex fault, you need the instrument according to the working principle, with a simple test instrument, with the instrument panel
