HH-1 工业用N -甲基二乙醇胺纯度测定毛细管柱的详细介绍
工业用N -甲基二乙醇胺纯度测定毛细管柱 详细信息:
浩瀚色谱(山东)应用技术开发有限公司建立了一种同时测定N-甲基二乙醇胺(MDEA)脱碳剂中MDEA和哌嗪(PIP)含量的毛细管气相色谱法,并采用GC-MS对实验结果进行了验证,同时考察了不同色谱柱、溶剂、脱水剂对测定结果的影响。实验结果表明,使用HH-1毛细管色谱柱、氢火焰离子化检测器,以甲醇为溶剂,试样不经脱水处理,采用外标法定量,即可同时测定MDEA脱碳剂中MDEA和PIP的含量。测定结果为:MDEA脱碳剂原液中MDEA含量99.0%~99.3%(w),PIP含量10.1%~10.4%(w);MDEA脱碳剂工作液中MDEA含量为41.4%~42.9%(w),PIP含量为7.3%~8.2%(w);MDEA回收率为96.43%~99.98%,PIP回收率为96.64%~102.02%;MDEA检出限为0.21μg/L,PIP检出限为0.29μg/L。该方法具有操作简便、分析速度快、准确、分离效果好、精密度高等特点,能满足工厂生产质检过程中的分析要求。

Determination of purity of N - methyldiethanolamine for industrial use Capillary column
Details of capillary column for purity determination of N - methyldiethanolamine for industrial use:
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a capillary gas chromatography method for the simultaneous determination of MDEA and piperazine (PIP) in N-methyldiethanolamine (MDEA) decarburizer. The experimental results were verified by GC-MS, and the effects of different chromatographic columns, solvents, and dehydrating agents on the determination results were investigated. The experimental results show that the co
