Gas Chromatographic Applications with the Dielectric Barrier Discharge Detector

Abstract

With gas chromatography, there are many more choices for detectors when compared to other separation disciplines in analytical chemistry. The presence of sensitive and selective detectors aids in easing the separation requirements imposed on the capillary column. The current gas phase detectors, however, do not completely fulfill contemporary analytical needs. One example is in the area of ultratrace analysis of permanent gases for semiconductor industry. Another example is in the area of environmental/industrial hygiene monitoring for compounds such as 1,3-butadiene or vinyl chloride. The dielectric barrier discharge detector, a new highly sensitive detector with tuneable selectivity, has recently been innovated and commercialized. In this paper, the principle of operation of the detector, along with critical challenging industrial applications such as the analysis of oxygenated compounds, sulfur-containing compounds, and other compounds of industrial significance is presented.

“…Gras et al invented and commercialized a DBD detector for GC (79). An electrometer was connected to one electrode and the second electrode was the grounding electrode.…”

Time-resolved spectroscopy of a homogeneous dielectric barrier discharge for soft ionization driven by square wave high voltage

“…They are easy to set up in simple and compact way, have low power consumption, and can operate over a wide pressure range with different discharge gasses. Therefore, the DBDs have found a wide range of analytical applications, such as the DBD atomizer for analytical atomic spectrometry [2,3], DBD detector for gas chromatography [4], DBD-induced and/or assisted chemiluminescence [5,6], and as the ionization source for ion-mobility spectrometry [7]. A comprehensive presentation of the history, principles, development, applications, and future prospects of this ionization source can be found in several reviews and articles [8][9][10][11][12][13].…”

Time-resolved line emission spectroscopy and the electrical currents in the plasma jet generated by dielectric barrier discharge for soft ionization

“…Due to their favorable characteristics, a number and diversity of DBDs applications have extended beyond the molecular mass spectrometry [5][6][7][8]. They have been used in many different scientific and technological areas, such as gas chromatography [9,10], ion mobility spectrometry [11,12], atomic fluorescence and diode laser spectrometry [13,14], element-selective detection [1], forensics [15,16], in vivo analysis [17][18][19], plasma cleaning [20,21], ozone generation for disinfecting water [22] and surfaces [23], pesticide testing [24], as light sources [25,26], and as sources for atomic emission spectroscopy [27,28].…”
