The improvement of the analytical performance of direct current atmospheric pressure glow discharge generated in contact with the small-sized liquid cathode after the addition of non-ionic surfactants to electrolyte solutions

Coupling of cold vapor generation with an atmospheric pressure glow microdischarge sustained between a miniature flow helium jet and a flowing liquid cathode for the determination of mercury by optical emission spectrometry

“…9,13,15,16,21,26 In our latest papers, 9,21 physicochemical properties of the liquid cathode solution were modied by addition of non-ionic Triton surfactants. The effect of size and concentration of Triton surfactants on the analytical performance of APGD-OES was investigated.…”

“…9 Commonly, these kinds of excitation sources provide favorable conditions for excitation of alkali metals, therefore, detection limits (DLs) of Li and Na are typically better than 1 mg L À1 . [7][8][9][10] The values of DLs of alkaline earth metals and transition metals are higher and usually span the range of 1-25 mg L À1 . [7][8][9][10][11][12][13][14] Considering the achievements made in the last 3 years in the application of APGD generated in contact with the liquid cathode as an efficient excitation source for analytical OES, it is evident that much effort has been devoted to improving the DL of Hg.…”

On the coupling of hydride generation with atmospheric pressure glow discharge in contact with the flowing liquid cathode for the determination of arsenic, antimony and selenium with optical emission spectrometry

“…They sheared a considerable interest and are the subject of a growing number of works [1][2][3]. Among developed and studied in recent years miniaturized excitation sources there are dielectric barrier discharge (DBD), electrolyte as cathode glow discharge (ELCAD), liquid sampling atmospheric pressure glow discharge (LS-APGD), solution cathode glow discharge (SCGD), capacitively coupled plasma (CCP) and microstrip plasma (MSP) [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In general, these new excitation sources enable efficient excitation of elements with relatively low excitation potentials, i.e., alkali and alkaline earth elements and some of transition metals.…”

“…In general, these new excitation sources enable efficient excitation of elements with relatively low excitation potentials, i.e., alkali and alkaline earth elements and some of transition metals. Limits of detection (LODs) of elements usually vary from several to tens micro gram per liter and because of that miniaturized excitation sources are commonly used for their quantification in different samples [4][5][6][7][8][9][10][11][12][13][14][15][16]. On the other hand, mentioned radiation sources are rarely utilized for the determination of elements with high excitation potentials, e.g., As, Sb or Se, with OES.…”

Sensitive and selective detection of cesium via fluorescence quenching

“…4 Current methods for detecting cesium in complex environments include atomic absorption spectroscopy (AAS), 5 inductively coupled plasma mass spectroscopy (ICP-MS), 6 and solid state sensors. 7 20 While these methods are highly sensitive and selective for cesium detection, they are often expensive and require sample destruction.…”
