摘要
为检测液氧/煤油发动机清洗后清洗剂中煤油含量,采用带温度程序的毛细管柱气相色谱法对液氧/煤油发动机组件用T3清洗剂清洗后清洗剂中残留的煤油组分进行分离,所得色谱峰峰形好且稳定,所选分析峰的峰面积与煤油含量在一定的浓度范围内呈线性关系。考察了分析条件、分析方法的重现性、精密度及检测限,建立了T3清洗剂中煤油含量的分析方法。该方法简便、快速、灵敏度高、检测限低,可用于判断液氧/煤油发动机组件清洗干净与否的标准。
To detect oil content in T3 cleaning egent after washing a liquid oxygen/kerosene engine component, capillary gas chromatography with the temperature process was adopted to seperate residual kerosene from T3 cleaning agent. The obtained peak-peak shape is good and stable, the peak areas of selected peaks and the content of kerosene is a linear relation in a certain range of kerosene concentration. The analysis method for determining the kerosene content in T3 cleaning agent is established under the consideration of reproducibility, accruacy and detective limit. This method is simple, fast and has high sensitivity, low detective limits. It can be used to establish the standard for clean level of the components been washed.
