摘要
气相色谱仪是用高纯气体作为流动相,待测样品或标准试样在气化室气化后被载气带入色谱柱,各组分在色谱柱内分离后,被检测器检测。基线是气相色谱仪运行中检测器信号的直接表现,也是仪器性能的综合表现,组成仪器的各部分发生故障、操作条件和外界条件的变化等因素都会反映到基线上,因此根据基线异常状况可以判断故障的原因和部位。
The gas chromatograph uses gas as the mobile phase,and the sample to be measured is brought into the column by the carrier gas after gasification in the gasification chamber,and the components are separated in the column and detected by the detector.The baseline is the comprehensive performance of the performance of the gas chromatograph in operation,and the failure of each part of the instrument,the change of operating conditions and external conditions and other factors will be reflected on the baseline,so the cause and location of the fault can be judged according to the baseline.
