本文介绍了用于光离子化气相色谱仪的一种真空紫外光源,给出了实现光源长寿命、高效的基本原则,例如工作气体、辐射能组、激发能量等参数的合理选择。使用这种灯(Kr)的光离子化气相色谱仪,灵敏度为10.SC/g,(苯),检出限为023pg(苯)。
This paper introduces a vacuum ultraviolet light source used in photoionization gas chromatograph, and gives the basic principles of long life and high efficiency of light source, such as working gas, radiant energy group, excitation energy and other parameters. A photoionization gas chromatograph using this lamp (Kr) has a sensitivity of 10. SC / g, (benzene), the detection limit of 023pg (benzene).
