浩瀚食品级二氧化碳中乙醇含量测定气相色谱仪GC7990

Carbon dioxide is widely used in nature, and is widely used in many industries. Beverage, beer and other products in the food industry is the need for a large number of carbon dioxide, China's food grade carbon dioxide annual sales of about 10 million T. Due to the different content of gas source components, production and purification device is different, resulting in a large number of these products are harmful to human health, alcohol, benzene, aldehydes and other substances.
Tengzhou Xiangying analysis GC7990 gas chromatography analysis of trace level group in carbon dioxide gas - Ethanol Technology Co. Ltd. the. The main influencing factors are the inlet temperature, the capillary column temperature, the temperature of the detector, the capillary column flow rate and the tail blow. The precision of the measurement is 0.6% and the linear error is not more than 2%. The method is fast and accurate, and can be applied to the analysis of the standard substance.
二氧化碳在自然界中广泛存在,在各行各业中被大量使用。食品行业中的饮料、啤酒等多种产品更是需要大量的二氧化碳,中国食品级二氧化碳的年销售量约为1000万t。由于气源组分含量不同、生产提纯装置不同,导致这些产品中含有大量对人体健康有害的烃、醇、苯、醛等物质。
滕州市翔鹰分析技术有限公司实验采用GC7990气相色谱法分析二氧化碳中的痕量级组分气体——乙醇。主要影响因素有进样口温度、毛细柱温度、检测器温度、毛细柱流速、尾吹,对各项优化后测得精密度为0.6%,线性误差不大于±2%。该方法快速、准确,可应用于该标准物质的分析定值。
