“…For instance, the suitability of DBD used as an atomizer for determining As, Sb and Se with atomic absorption spectrometry (AAS) and atomic fluorescence spectrometry (AFS) has already been reported for several years [19][20][21][22]. Use of the same discharge as the excitation source in determination of As by OES has been reported just recently [23]. Also other miniaturized excitation sources, e.g., SCGD [15,16], CCP [24,25] or MSP [26,27] were used for the determination of As, Sb or Se with OES just a few times.…”

“…However, no measurable arsenic emission signal could be obtained with the planar DBD when coupling with HG. Until 2014, arsenic determination was achieved with a cylindrical DBD but with a limit of detection of 4.8 μg L –1 . Frentiu et al reported simultaneous determination of As and Sb in soil using CCP microtorch by coupling with HG .…”

In this paper, a sensitive atomic emission spectrometer (AES) based on a new low power and low argon consumption (<8 W, 100 mL min) miniature direct current (dc) atmospheric pressure glow discharge (APGD) plasma (3 mm × 5 mm) excitation source was developed for the determination of arsenic in water samples. In this method, arsenic in water was reduced to AsH by hydride generation (HG), which was then transported to the APGD source for excitation and detected by a compact CCD (charge-coupled device) microspectrometer. Different parameters affecting the APGD and the hydride generation reactions were investigated. The detection limit for arsenic with the proposed APGD-AES was 0.25 μg L, and the calibration curves were found to be linear up to 3 orders of magnitude. The proposed method was successfully applied to the determination of certified reference material (GBW08605), tap water, pond water, groundwater, and hot spring samples. Measurements from the APGD analyzer showed good agreement with the certified value/values obtained with well-established hydride generation atomic fluorescence spectrometry (HG-AFS). These results suggest that the developed robust, cost-effective, and fast analyzer can be used for field based arsenic determination and may provide an important tool for arsenic contamination and remediation programs.

“…For this purpose, a cylindrical DBD was designed for the excitation of arsenic followed by OES detection. 45 Arsine or arsenic hydride was transported to the DBD micro-plasma for excitation and the emission was detected at 193.7 nm by use of a photomultiplier tube with a monochromator. This system provided a detection limit of 4.8 mg L À1 .…”

During the last years, various miniaturized optical emission spectrometric (OES) systems based on dielectric barrier discharge (DBD) micro-plasma as a radiation source have gained novel advances and exhibited powerful capability in the field of trace elemental analysis. As the heart of such analytical systems, DBD micro-plasma possesses a series of unique features and it is a promising technique for the development of miniaturized atomic spectrometric instrumentations, including OES spectrometers. This mini-review presents and 10 discusses the progress of DBD-OES systems in the analysis of gaseous species and those in aqueous medium. In the case of gaseous species, the approaches are focused on direct detection by DBD-OES after appropriate sample introduction. For the case of analyzing target species in aqueous medium, the entire analytical process includes DBD-OES detection unit, electrothermal vaporization or chemical vapor generation unit. Special emphasis has been focused on the novel applications of DBD-OES systems and its hyphenation with various analytical techniques. Future perspectives of DBD-OES systems for trace elemental analysis have been depicted. 15 65
