“…Similar results were achieved by Leasure, Fleisher, Anderson, and Eiceman, 19 who also used a UV-IMS with detection limits of 15 ppb v for benzene and 10 ppb v for p-xylene, with nitrogen as the drift gas.…”

“…Unfortunately, the linear working ranges of such IMSs are limited, the selectivity is inflexible and sometimes poor, and many regulatory requirements exist because radioactive material is used. An attractive alternative is the application of UV-lamps, [19][20][21] which are routinely used in photoionization detectors (PID) for gas chromatography. Suitable UV-lamps are available with photoionization energies between 8.6 and 11.7 eV.…”

An ion mobility spectrometer (IMS) equipped with a 10.6 eV low‐pressure gas‐discharge lamp usually used in photoionization detectors for gas chromatographic applications was developed for the continuous detection of benzene, toluene, and m‐xylene. To improve the resolution of the IMS for single substances a customized IMS with a doubled drift tube length was built. The responses of both IMS (drift tube lengths of 6 and 12 cm) to the compounds selected were determined and compared. The advantages of the combination of multi‐capillary columns with IMS are discussed with the aim of achieving further enhancements to the resolution of the instrument. This coupling leads to a significant increase in the scope of application of ion mobility spectrometry for environmental applications. The influence of intermolecular charge‐transfer reactions on the peak can be reduced and more complex matrices considered. The presented three‐dimensional correlation supports the interpretation of the spectra acquired from the mixtures. © 2000 John Wiley & Sons, Inc. Field Analyt Chem Technol 4: 157–169, 2000

“…They have been used for the detection and quantitation of those classes of chemical compounds that are ionizable by a suitable vacuum-UV radiation. Some reports describe applications and developments of such a technology (Baim, Eatherton, &Hill, 1983;Leasure et al, 1986;Spangler et al, 1994) that were carried out with and without the addition of a dopant.…”

Atmospheric pressure photoionization (APPI) is the last arrival in the family of atmospheric pressure ionization (API) methods to couple mass spectrometry (MS) to liquid-phase separation techniques. The basic idea was to further extend the fields of application of liquid chromatography (LC)-MS to those molecules that are not, or are poorly amenable, to electrospray (ESI) or APCI. The present review explores the literature. After a short introduction with an historical background and the premises for its development, we describe the technique, its physical principles, and the factors that affect its efficiency. The review also presents a survey of applications in different fields.

“…Eiceman et al constructed a photoionization ion mobility spectrometer using an on-axis mounted 10.2-eV hydrogen discharge lamp in air, and ten organic compounds were detected with detection limits from 0.1 to 50 ppb and working ranges were improved 100-to 1000-fold. 14 Baumbach and Sielemann reported a membrane inlet ion mobility spectrometer (IMS) with radioactive and UV ionization sources in combination with multicapillary columns (MCCs) for realtime monitoring of methyl tert-butyl ether (MTBE) in water and nitrogen as well as the monoaromatic compounds benzene, toluene, and m-xylene (BTX). 15 Recently, Tabrizchi described an ion mobility spectrometer equipped with an atmospheric pressure photoionization and a corona discharge ionization source and observed peaks from either the corona discharge or photoionization individually or simultaneously, which makes it possible to accurately compare peaks in the ion mobility spectra from each individual source.…”

Dopant-Assisted Negative Photoionization Ion Mobility Spectrometry for Sensitive Detection of Explosives

et al. 2012

Ion mobility spectrometry (IMS) is a key trace detection technique for explosives and the development of a simple, stable, and efficient nonradioactive ionization source is highly demanded. A dopant-assisted negative photoionization (DANP) source has been developed for IMS, which uses a commercial VUV krypton lamp to ionize acetone as the source of electrons to produce negative reactant ions in air. With 20 ppm of acetone as the dopant, a stable current of reactant ions of 1.35 nA was achieved. The reactant ions were identified to be CO 3by atmospheric pressure time-of-flight mass spectrometry, while the reactant ions in 63 Ni source were O 2. Finally, its capabilities for detection of common explosives including ammonium nitrate fuel oil (ANFO), 2,4,6-trinitrotoluene (TNT), N-nitrobis(2-hydroxyethyl)amine dinitrate (DINA), and pentaerythritol tetranitrate (PETN) were evaluated, and the limits of detection of 10 pg (ANFO), 80 pg (TNT), and 100 pg (DINA) with a linear range of 2 orders of magnitude were achieved. The time-of-flight mass spectra obtained with use of DANP source clearly indicated that PETN and DINA can be directly ionized by the ion-association reaction of CO 3 − to form PETN·CO 3 − and DINA·CO 3 − adduct ions, which result in good sensitivity for the DANP source. The excellent stability, good sensitivity, and especially the better separation between the reactant and product ion peaks make the DANP a potential nonradioactive ionization source for IMS.
