摘要
目前高纯异丙醇已广泛应用在精密电子、半导体等行业。随着相关行业技术的发展,对高纯异丙醇的纯度提出了更高的要求。文章利用气相色谱仪探究高纯异丙醇最佳检测方法,结果表明异丙醇含量的最佳分析方法为:色谱柱初始温度为50℃,最终温度为200℃,中间升温速率为10℃/min,气化室温度为150℃,检测室温度为200℃,检测的分流比1∶100,色谱柱流量为1 mL/min,样品的进样量为0.5μL。
Currently,high-purity isopropanol has been widely used in the cleaning and drying of precision electronics.As the processing size ofintegrated circuits enters the era of submicron and deep submicron,higher requirements are put forward for the purity of high-purity isopropanol matched with them.This article uses a gas chromatograph to explore the best detection method for high-purity isopropanol.The results show that the best analysis method for isopropanol content is:the initial temperature of the chromatographic column is 50 ℃,the final temperature is 200 ℃,the intermediate heating rate is 10 ℃/min,the gasification chamber temperature is 150 ℃,the detection chamber temperature is 200 ℃,the detection split ratio is 1∶100,and the chromatographic column flow rate is 1 mL/min.The sample injection amount of the sample is 0.5 μL.
