气相色谱法分析Ar+N_2含量准确性的探讨

DISCUSSION OF THE ACCURACY FOR ANALYZING Ar+N_2 WITH CHROMATOGRAPHY

探讨了采用TDX 0 1碳分子气相色谱法分析高、低变出口气中Ar +N2 的含量时 ,高变出口气中Ar+N2 的含量比低变出口气中Ar+N2 的含量低的原因。采用峰高测量法代替峰面积测量法 ,可以消除数据处理机对色谱峰重叠处理时造成的偏差 ,测定值与实际值相符合 。

The Ar+N 2 content in high temperature shift exit gas was lower than that in low temperature shift exit gas when TDX 01 carbon molecule gas chromatography was used. This abnormal results mainly owe to the defaults of data processor during the overlapping of the peaks.While we use peak height method to replace peak area integerating method,the analytical results are satisfactory,which coincide with the real value.
