戊二醛是目前医院常用的醛类消毒剂,具有杀菌广谱、杀细菌芽孢效果可靠、杀菌作用受有机物影响较小、对金属腐蚀性小等特点,应用十分广泛。戊二醛的浓度影响杀菌效果,目前消毒液中戊二醛含量的定量分析主要依据卫生部《消毒技术规范》,该方法测定时间长,试剂使用量大,溴酚蓝指示剂突跃范围小,滴定终点较难掌握。用气相色谱法测定戊二醛具有操作简便,快速,选择性强,灵敏度高的特
Glutaraldehyde is commonly used in hospitals aldehyde disinfectant, with broad-spectrum bactericidal, bactericidal effect of bacterial spores reliable, bactericidal effect less affected by organic matter, the characteristics of small metal corrosive, is widely used. The concentration of glutaraldehyde affects the bactericidal effect. At present, the quantitative analysis of glutaraldehyde in disinfectant is mainly based on the “Technical Specifications for Disinfection” of the Ministry of Health. The method has a long determination time, large amount of reagents and a small jumping range of bromophenol blue indicator Titration end point difficult to master. Determination of glutaraldehyde by gas chromatography with simple, fast, selective, high sensitivity
