103气相色谱仪热导池不能调零的故障在日常维修中经常会碰到。它集中表现在热导电源开启后。电桥电流正常可调,但桥路却无法调平衡。出现上述现象后,我们首先必须排除气路是否漏气,或是否存在两路载气流量不一致等情况。因为气路失衡也是产生调零困难的原 103 Gas Chromatograph heat conduction pool can not zero the fault often encountered in routine maintenance. It focuses on the thermal conductivity of the open source. Bridge current adjustable, but the bridge can not be balanced. After the above phenomenon, we must first rule out whether the gas leaks, or whether there is inconsistency between the two carrier gas flow and so on. Because the airway imbalance is also produced before the original zero adjustment
