Design and optimization of a corona discharge ionization source for ion mobility spectrometry

Abstract: In this work the possibility of using corona discharge as an ionization source in ion mobility spectrometry has been investigated. The results for both positive and negative polarity in air are consistent with the Townsend formula which states that I/V is a linear function of V. The distribution profile of the corona ions has also been investigated and compared with that of the Ni63 ionization source. Generally, the total ion current obtained from the corona ionization source was greater than that of the Ni63 … Show more

“…Use of a corona discharge ionization source for IMS has been the main interest in recent IMS development [17,18]. Aside from radioactive-material safety issues, the corona discharge ionization source provides better signal-to-noise ratio than the 63 Ni source.…”

“…A continuously working corona discharge-based source was investigated regarding its usefulness for IMS by Tabrizchi et al (2000) . Although it was initially intended only to be a non-radioactive alternative, the corona discharge source showed greatly improved ionization efficiency and thus signal intensity as well as signal-to-noise-ratio.…”

“…Regarding the electron source, prominent examples are electrospray ionization (typically for liquid samples) (Wittmer et al 1994, Chen et al 1996, Wu et al 2000, Harris et al 2008, Yamagaki and Sato 2009, optical sources (high-intensity light sources resp. laser, X-ray) (Matsaev et al 2002, Sielemann et al 2002, Oberh ü ttinger et al 2009 ), corona discharges (Tabrizchi et al 2000, Schmidt et al 2001, Khayamian et al 2003, Han et al 2007, Mulugeta et al 2010, Tabrizchi and Ilbeigi 2010, and electron guns (Gunzer et al 2010a ). These sources were also examined in order to have non-radioactive alternatives because of the technical, organizational and related financial complications that accompany the application of radioactive substances.…”

“…In addition to these popular continuous ionization sources, there are current reports in exploring pulsed ionization sources for IMS. Pulsed corona discharge ionization and distributed plasma ionization were developed as alternative non-radioactive ionization sources [65][66][67][68][69][70]. MALDI was used as a interchangeable replacement of EDI to make use of its capability to form primarily singly charged ions and its ability to ionize bio-and synthetic polymers [71][72][73][74][75][76].…”
