“…So far, various microsystems were proposed to sustain APGD generated in contact with analyzed sample solutions and determine in them different elements using this excitation source (Franzke and Miclea, 2006;Mitra et al, 2008;Jamroz et al, 2012;Schwartz et al, 2016). Miniaturization of these systems can significantly reduce costs of element analysis and amounts of samples required for this.…”

Purpose The purpose of this paper is to present a study on miniaturized instruments for analytical chemistry with a microplasma as the excitation source. Design/methodology/approach The atmospheric pressure glow microdischarge could be ignited inside a ceramic structure between a solid anode and a liquid cathode. As a result of the cathode sputtering of the solution, it was possible to determine its chemical composition by analyzing the emission spectra of the discharge. Cathodes with microfluidic channels and two types of anodes were constructed. Both types were tested through experimentation. Impact of the electrodes geometry on the discharge was established. A cathode aperture of various sizes and anodes made from different materials were used. Findings The spectroscopic properties of the discharge and its usefulness in the analysis depended on the ceramic structure. The surface area of the cathode aperture and the flow rate of the solution influence on the detection limits (DLs) of Zn and Cd. Originality/value Constructed ceramic structures were able to excite elements and their laboratory-size systems. During the experiments, Zn and Cd were detected with DLs 0.024 and 0.053 mg/L, respectively.

“…One method that overcomes these issues is the use of microplasma sources especially for liquid sample analysis. [1][2][3][4][5] There are a miniaturized atmospheric-pressure thermal plasma jet source, 6 electrolyte-cathode discharge (ELCAD), which is an atmospheric glow discharge in the air gap between a owthrough electrolyte solution cathode and a metal anode, [7][8][9][10][11][12] liquid-sampling atmospheric-pressure glow discharge (LS-APGD) that uses a conductive tube to deliver the sample 13,14 and so on. The other reported method using both electrodes consisting of solutions is discharge on boiling in a channel.…”

“…Recently, due to the growing demand for miniaturized instruments, there is a significant interest in developing small size plasma as part of the detector [15][16][17][18][19][20]. Several plasma sources have been explored, including the microwave induced plasma(MIP) [21][22][23], the capacitively coupled plasma (CCP) [24], the inductively coupled plasma(ICP) [25], the glow discharge(GD) [26], and the dielectric barrier discharge(DBD) [27,28].…”
