二氧化碳相变致裂装置加热剂的阴阳离子快速分析

Analysis of Carbon Dioxide Phase Change Fracturing Device Heater by Ion Chromatography

建立了二氧化碳相变致裂装置加热剂的离子色谱分析方法。使用Dionex IonPac AS-19高容量阴离子分析柱可同时分析三种加热剂成分的阴离子,确定了3种阴离子和3种阳离子的保留时间,实现定性分析。对6种离子以峰面积Y对相应的质量浓度X(μg/mL)进行线性回归,绘制了标准曲线,并确定了相应的线性范围、检出限和定量限。方法灵敏度高,检出限低,稳定性好,可为公安机关在相应案件中对二氧化碳相变致裂装置中加热剂的检测提供依据。

The method was established for the analysis of CO_(2) phase change fracturing device heating agents by ion chromatography.A high-capacity Dionex IonPac AS-19 column was used for the simultaneous analysis of the three heater component anions and the retention times were determined for three anions and three cations.The linear regression of the peak area Y on the corresponding mass concentration X(μg/mL)for the six ions was performed,a standard curve was plotted and the corresponding linear ranges,the limits of detection,and the limits of quantification were determined.The method is sensitive,with low detection limits and good stability,and can provide a basis for the detection of heating agents in CO_(2) phase change fracturing devices by public security authorities in the corresponding cases.
