气相色谱红外光谱（ＧＣＩＲ）联用技术，在催化反应产物分析及催化机理的研究中具有独到的优越性．利用气相色谱红外光谱联用仪，对多相催化反应（如环己烯在ＴＳ１分子筛催化剂存在下的双氧水氧化反应）产物及均相催化反应（如α（６′甲氧基２′萘）乙醇羰基化合成萘普生）产物进行分析，捕捉到了一些对催化反应机理研究产生影响的物种．
Gas chromatography-infrared spectroscopy (GC IR) technology, in the catalytic reaction product analysis and catalytic mechanism has unique advantages. The use of gas chromatography-infrared spectroscopy, heterogeneous catalytic reactions (such as cyclohexene in the presence of TS zeolite catalyst hydrogen peroxide oxidation reaction) products and homogeneous catalytic reaction (such as α (6 methoxy 2 ’- naphthalene) ethanol carbonylation of naproxen) products were analyzed to capture some of the catalytic reaction mechanism influencing species.
