“…The to 0.8 Torr with air [7]. PETN, on the other hand, provided the adduct ion ([PETN+NO3] -, m/z 378) as the major ion when ionized at atmospheric pressure [10,11,21,29,30,98], which was similarly seen for RDX (Fig. 4a1).…”

“…Many attempts have been made to understand the processes occurring in the HCD since Friedrich Paschen's pioneering work in 1916 [29][30][31][32][101][102][103][104][105][106][107][108][109][110][111][112][113][114][115][116][117][118]. Despite the fact that the hollow cathode effect and conventional glow discharge (GD) are two distinct electrical processes, some of their properties were assumed to be the same.…”

“…The development of ambient ion sources is the only approach to fabricate miniaturized-MS systems that can analyze relevant analytes at trace to ultra-trace levels. Accordingly, many efforts have been made to develop ambient ion sources for mass spectrometer, such as desorption electrospray ionization (DESI) [69][70][71][72][73], probe electrospray ionization (PESI) [74][75][76], atmospheric pressure chemical ionization (APCI) [17,18,[77][78][79], direct analysis in real time (DART) [80][81][82], matrix-assisted laser desorption/ionization (MALDI) [83][84][85][86][87][88][89][90] and desorption atmospheric pressure chemical ionization (DAPCI) [91], electrospray-assisted laser desorption/ionization (ELDI) [92], dielectric barrier discharge ionization (DBDI) [21,[28][29][30][93][94][95][96][97][98][99].…”

“…On the other hand, fragmentation may improve the sensitivity of particular analytes. For example, when 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) was fragmented to ([M-NO2-HNO2] -, m/z 129), the limit of detection (LOD) was found to be 10.33±0.45 pg, whereas the LOD for its adduct ion, ([RDX+NO3] -, m/z 284) was 30.75±0.95 pg [21,23,[29][30][31]. According to McLuckey et al (1996), RDX's sensitivity has increased as it has fragmented to ([RDX-NO2] -, m/z 176) [7].…”

“…The essential step in the MS analysis is gasification of the analytes of interest. We recently developed an ultrasonic cutter-based desorption method for gasification of highly nonvolatile compounds such as explosives, drugs of abuse, herbicides, steroids, ionic liquids, rhodamine B, sugars etc, which were ionized using a homemade He-DBDI and analyzed using an ion trap MS [21,29,30].…”

Mass spectrometry (MS) has become an essential analytical method in every sector of science and technology. Because of its unique ability to provide direct molecular structure information on analytes, an extra method is rarely required. This review describes fabrication of a variable-pressure hollow cathode discharge (HCD) ion source for MS in detection, quantification and investigation of gas-phase ion molecule reactions of explosives and related compounds using air as a carrier gas. The HCD ion source has been designed in such a way that by altering the ion source pressures, the system can generate both HCD and conventional GD. This design enables for the selective detection and quantification of explosives at trace to ultra-trace levels. The pressure-dependent HCD ion source has also been used to investigate ion-molecule reactions in the gas phase of explosives and related compounds. The mechanism of ion formation in explosive reactions is also discussed.

Ambient ionization mass spectrometry (AIMS) has revolutionized the field of analytical chemistry, enabling the rapid, direct analysis of samples in their native state. Since the inception of AIMS almost 20 years ago, the analytical community has driven the further development of this suite of techniques, motivated by the plentiful advantages offered in addition to traditional mass spectrometry. Workflows can be simplified through the elimination of sample preparation, analysis times can be significantly reduced and analysis remote from the traditional laboratory space has become a real possibility. As such, the interest in AIMS has rapidly spread through analytical communities worldwide, and AIMS techniques are increasingly being integrated with standard laboratory operations. This annual review covers applications of AIMS techniques throughout 2021, with a specific focus on AIMS applications in a number of key fields of research including disease diagnostics, forensics and security, food safety testing and environmental sciences. While some new techniques are introduced, the focus in AIMS research is increasingly shifting from the development of novel techniques toward efforts to improve existing AIMS techniques, particularly in terms of reproducibility, quantification and ease-of-use.
