[交流] HPLC测量乙二醇,苯,甲苯,二甲苯 已有5人参与

本人正在做毕业论文,石油工业废水处理的,含有乙二醇,苯,甲苯和二甲苯,现在需要用到HPLC来测其单一物质溶液的浓度,请问有人测过这些物质吗?参数什么的分别是怎么设定的?急求。。。网上搜索半天,中英文都没有收获。。。

乙二醇没有紫外吸收,除非你换其他的检测器!气相可以检测这四种物质。液相紫外检测器可以检测那三种,方法随便,都是色谱柱性能测试用样品

用气相色谱做就OK的了,液相的话得用到示差检测器才行呢,乙二醇紫外吸收很弱的

气相就可以搞定,极性柱,程序升温。
柱箱 50℃保持2min,10℃每分升到230
进样口 230℃
检测器 230℃

Can GC be used to measure these four solutions? The concentrations of them are all 100 ppm. After treatment the concentrations are all about 5-10 ppm. How about the mixture of them, can GC measure them too? If I use GC, what the parameters(e.g column) should I choose? The GC equipment I will use is Agilent Tech. 6890N. Thx a lot.
P.S. There is no chinese in this PC. Sorry about that.

Is that OK to use capillary column (30m*0.25mm*0.25um)?
