定量分析CO2气体碳同位素组成的激光拉曼检测方法
摘要：
本发明提供了一种定量分析CO2气体碳同位素组成的激光拉曼检测方法，包括以下步骤：一、计算12CO2的拉曼量化因子F12CO2；二、计算13CO2的拉曼量化因子F13CO2；三、根据公式C[12CO2]/C[13CO2]＝(A12CO2/A13CO2)×(F13CO2/F12CO2)计算出CO2气体中12CO2和13CO2的摩尔比C[12CO2]/C[13CO2]。本发明对不同比例12CO2/N2混合气体和13CO2/N2混合气体进行显微激光拉曼测试分析，采用的显微激光拉曼光谱法具有高精度、原位、无损和快速等特点，利用显微激光拉曼光谱法能够定量分析CO2碳同位素的组成，具有广泛的应用前景。
