Gas analysis is an ancient and young subject, it is a research and development at room temperature and pressure of gaseous material composition and content analysis method. According to gas content analysis accuracy requirements of the type of the target gas, analysis, analysis of the testing purpose and occasion and adaptability of different, modern analysis test tool types and test methods.
xiang ying analysis technology CO., LTD adopts XingyingGC7990plus gas chromatography for the characteristics of strong chemical activity and strong corrosion, using modified compound silica column as the CO2 and O2, N2 and CO separation column, and then USES the 5 a column separation of O2, N2 and CO, by double column switching, counter blowing method to protect the 5 a column column, effectively realized the separation of O2, N2 and CO in the yellow phosphorus tail gas measurement. Chromatographic conditions for injection port and column temperature: room temperature, detector (TCD) : 100 ℃, 100 mA bridge flow; Head pressure: 0.075 MPa, carrier gas flow rate: 32 m l/m in CO2 back switch time: 4 m in instrument working state is stable, good separation effect, the analysis results RSD % is less than 0.7.
气体分析是一门既古老又年青的学科,它是研究、开发在室温和常压下气态物质的组成及含量的分析方法。根据气体含量分析准确度要求的不同、分析气体目标种类的不同、分析检测目的的不同以及场合性和适应性要求的不同,现代常用的分析测试工具种类及测试方法繁多。
滕州市翔鹰分析技术有限公司采用XingyingGC7990plus气相色谱针对黄磷尾气化学活性强和腐蚀性强的特点,采用改性复合硅胶柱作为CO2与O2、N2及CO的预分离柱,然后采用5A柱分离O2、N2和CO,通过双柱切换,反吹预柱的方法保护了5A柱,有效实现了黄磷尾气中O2、N2和CO的分离测定。色谱条件为进样口与柱温:室温,检测器(TCD):100℃,桥流100 mA;柱头压:0.075 MPa,载气流量:32 m l/m in.CO2反吹切换时间:4 m in.仪器工作状态稳定,分离效果良好,分析结果RSD%小于0.7.
