气相色谱法分析气体中组分的加速

Gas chromatographic analysis of gaseous components in acceleration

通过对气相色谱法分析气体样品N2、CO、CH4、CO2的实验方法中进样阀动作时间做相应的调整,第1次动作,第1个样品进样;第2次动作,第2个样品开始置换;第3次动作,第2个样品进样;第4次动作,阀复位到初始状态。在满足各色谱峰能够完全分离且分离度大于1.5的条件下,在对多个样品进行分析时,可以节省分析时间43%,RSD<0.010%。

Gas chromatography analysis of gas samples N2,CO,CH4,CO2 of the experimental method in the injection valve operating time adjusted accordingly,first action：the first sample injection;second action：the second sample begin replacement;third action：the second sample injection;the fourth action：the valve reset to the initial state.The peaks were the completely separated and separation was greater than 1.5.Under the conditions of this method in the analysis of multiple samples,analysis time can be saved 43%,RSD was less than 0.010%.
