“…The limits of detection (LODs), calculated using the definition 3 s / m ( s is the standard deviation of 9 measurements of the blank and m is the slope of the calibration curve), were in the range of 0.25–0.37 μg L –1 using different emission lines. The obtained LODs is improved by about 1 order of magnitude compared with other miniaturized plasma sources such as DBD, point discharge, and LFC-APGD and is comparable to that obtained with μCCP (0.2 μg L –1 ), where a QE65 Pro microspectrometer equipped with a Peltier cooled CCD at −20 °C was employed. Repeatability based on the variability of peak height (193.7 nm) of the standard was estimated.…”

“…37 Frentiu et al reported simultaneous determination of As and Sb in soil using CCP microtorch by coupling with HG. 29 In 2015, Greda et al 38 reported determination of As, Sb, and Se using a atmospheric pressure glow discharge (HG-He-APGD) generated between a He nozzle jet and a liquid flowing cathode (LFC). Despite these developments, to the best of our knowledge, there is no report of any portable atomic emission spectrometer developed for arsenic determination in water samples, perhaps because of high detection limits or lack of portability.…”

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.

“…Similar observations were made for Ge and Sn, although the effects were less pronounced, particularly in the case of Ge. Therefore, these observations, mainly due to the HG efficiency, improve with an increase in NaBH 4 concentration in a certain range, which are similar to those reported by Greda et al 30 When the HG efficiency improves, the intensities of the Se, Ge, and Sn emission lines increased, thus resulting in lower DLs. However, upon increasing the NaBH 4 concentration beyond the optimal value, decomposition likely took place, generating H 2 , impacting signal stability, and yielding higher DLs.…”

We herein describe a novel method of hydride generation (HG) coupled to a newly designed atmospheric pressure solution-cathode glow discharge (SCGD) spectrometric technique for the ultratrace determination of tin, germanium, and selenium. In this novel SCGD process, gas introduction was permitted using a hollow titanium tube as both the anode and sampling port. In these experiments, the analytes were converted into volatile hydrides upon passing through the hydride generator, and were introduced into the near-anode region of the SCGD system, where they were detected directly by atomic emission spectrometry (AES). A significant improvement in both selectivity and sensitivity was achieved, which was reflected in an improvement in the detection limits (DLs) by 3 orders of magnitude, in addition to successful valence analysis of Se without the requirement for chromatographic separation. In the absence of a strict sample pretreatment process and with a reduction in electrolyte consumption, the detection limits of Sn, Ge, and Se were determined to be 0.8, 0.5, and 0.2 μg·L. Moreover, our HG-SCGD-AES system demonstrated excellent repeatability (<3% peak height relative standard deviation) and more than 2 orders of linear dynamic range. The optimal operating conditions are outlined herein, and the analytical performance of the system is evaluated as described. Furthermore, our method was applied for the analysis of Sn, Ge, and Se in both environmental and biological samples, and the obtained results were in good agreement with reference values.

“…Over past few years, a significant interest in new applications of plasma‐liquid interactions (PLIs) has been observed, particularly in relation to their usage in environmental engineering, microbiology, analytical chemistry, and nanotechnology . The use of large quantities of nanomaterials, especially silver (AgNPs) and gold nanoparticles (AuNPs) of well‐defined optical properties and morphology, appears to be necessary nowadays in a broad range of application fields, including medicine, sensing, environmental engineering, and catalysis .…”

Direct current atmospheric pressure glow discharge (dc‐APGD), generated between a pin‐type tungsten solid cathode and the surface of a flowing liquid anode (FLA), was used to synthesize Ag nanoparticles (AgNPs) and gelatin‐stabilized Ag nanoparticles (GEL‐AgNPs) in a flow‐through plasma‐reaction system. To characterize the nanostructures, UV/Vis absorption spectrophotometry, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) were applied. Resulting GEL‐capped AgNPs were more stable and lower in size than AgNPs. By applying attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT‐IR) and FT‐Raman spectroscopy, possible functionalization of the AgNPs surface by GEL after dc‐APGD treatment was examined. The described method was robust and provided high amounts of the suspensions of nanocolloidal Ag.
