查询词典 sample

In the determination of methyl acrylate,butyl acrylate and methyl methacrylate in ambient air,the sample was absorbed with active carbon and resolved with carbon bisulfide,and then determined by GC.

测定环境空气中的丙烯酸甲酯、丙烯酸丁酯和甲基丙烯酸甲酯时，气样采用活性炭吸附，用二硫化碳解析，直接进气相色谱仪检测，根据保留时间定性，外标法定量，能获得良好的线性和较低的方法检出限，不仅精密度、灵敏度和重复性良好，而且可操作性强，易于在环境监测系统中推广。
