摘要/Abstract

摘要： 紫外光电离源是离子迁移谱中最重要的电离源之一，常被用来电离有机物，产生正离子。利用紫外光照射金属表面产生电子作为离子源，建立了一套光电子源离子迁移谱仪，由于卤化物具有较强的吸附电子能力，该装置可以应用于卤化物的检测。使用CCl4样品，得到了该装置的离子峰强度、半峰宽、分辨率随迁移管电场、离子门脉宽、离子门电压的变化关系，并进行了简单的理论分析。兼顾离子峰强度与分辨率，得到了优化的实验参数，在该参数下测量了CCl4的检测限达到4 ppb，线性范围跨越2个数量级。

Abstract: With a photoelectron source induced by ultraviolet radiation on mental surface, a photoemission ion mobility spectrometry (PE-IMS) was set up, which can be used to detect halide since halide has a good ability to attach electron. Using CCl4 sample, the evolutions of the ion intensity, full width at half maximum and resolution versus drift electric field, ion gate pulse width and ion gate voltage were got, and the reasons for the evolutions were analyzed simply. Taking into account both ion intensity and resolution, optimized experimental parameters were got. The PE-IMS has a limit of detection at 4 ppb for CCl4 and its measurable linear dynamics range is over two orders of magnitude in the optimized experimental parameters.

Key words: spectroscopy, ion mobility spectrometry, photoemission, photoelectron source, tetrachloromethane
