Parameters and performance analysis of photoionization ion mobility spectrometry

Abstract

Abstract:

The construction and performance study is reported for a newly developed photoionization ion mobility spectrometry (UV-IMS). An ion mobility spectrometry equipped with a 10.6eV Kr lamp has been developed. The effect of the total voltage of drift tube, pulse width and voltage of ion gate on resolving power and sensitivity of UV-IMS were discussed. The optimal values with the detection of benzene are 2153V, 0.15ms and 80V, respectively. The concentrations of benzene were prepared by means of exponential dilution method. The experiments show that the UV-IMS has a limit of detection at 400 ppt for benzene and its measurable linear dynamics range is over three orders of magnitude.

Key words: spectroscopy, UV-IMS, photoionization, benzene, resolution
