图书馆文献库房挥发性有机化合物的监测与分析

Monitoring and Analysis of Volatile Organic Compounds in Stack Rooms

库房环境是影响文献保存寿命的重要因素。除温度和湿度外,挥发性有机化合物对文献的影响不容忽视。文章采用热脱附-气质联用技术测定配备不同类型装具的库房中挥发性有机化合物。研究发现,温湿度控制较好的库房环境优于其他库房,配备金属书架的库房环境优于配备其他类型装具的库房,库房中挥发物具有季节性变化的特征。

The environment of stack rooms in a library must be a key factor affecting the preservation life of literature. Aside from temperature and humidity, volatile organic compounds also play an ignorable role in the preservation of literature. In this paper,the thermal desorption-gas chromatography-mass spectrometry is used to determine what kind of volatile organic compounds there are in stack rooms with different equipments. It is shown that in stack rooms with a good control of temperature and humidity,there are fewer volatile organic compounds,and stack-rooms with metal shelves are better than those with other kinds of shelves. Besides, the content of volatile organic compounds in stack rooms might vary with the change of seasons.
