SPME-GC-FTIR联用分析水处理药剂

Analyzing Water Treatment Agent with SPME-GC-FTIR

利用固相微萃取-气相色谱-傅里叶变换红外光谱联用技术对水处理药剂成分进行了剖析。用程序升温，检测出10多个组分，其中10个组分给出定性结果，依保留时间增大顺序10个峰分别为水、1，2丙二醇、N，N二甲基十二烷基胺、癸醛、硫醇、N，N二甲基十二烷基胺同系物、1-溴十一烷、N，甲基二辛胺及其两个同系物。定性结果与红外标准谱图的匹配率均在90％以上。

The composition of water treatment agent was analyzed by using of SPME-GC-FFIR method. More than 10 components were detected by programmed temperature. 10 components were determined qualitatively according to retention time, including water, 1,2-propanediol, N,N-dimethyl dodecylamine, decanal, thiol, homological compounds of N,N-dimethyl dodecylamine, 1-bromoundecane, N-methyldioctylamine and its two homological compounds. The matching rate between the results and standard FFIR spectra was over 90%.
