微电流放大器是气相色谱仪氢焰检测电路的重要组成部分,它的稳定性直接影响色谱仪的性能,零点漂移是微电流放大器常见故障之一,它使基线漂移,色谱分析工作无法正常进行.因此必须正确判断微电流放大
Micro-current amplifier is an important part of the gas chromatograph hydrogen flame detection circuit. Its stability directly affects the performance of the chromatograph. Zero drift is one of the common faults of the micro-current amplifier. It makes the baseline drift and the chromatographic analysis work abnormally. Therefore, we must correctly judge the micro-current amplification
