“…Changes in the spectral emission patterns and the intensities of analyte lines were used to detect H 2 , O 2 , N 2 , CO 2 , and Ar. A similar 40.68-MHz miniaturized capacitive plasma device coupled to a GC was reported by Cziesla et al (50), which was distinguished from previous systems by its extremely simple construction and high robustness. A plasma with a diameter of 140 μm was coupled to a near-infrared echelle spectrometer, which was designed to detect various nonmetals in the near-infrared spectral range, especially the halogens and sulfur.…”

Microplasma is a useful detector for analyzing the effluent of gas chromatography due to its remarkable capacity for portability, high sensitivity, and excellent multielement selectivity. Compared to classical detectors, microplasma detectors have the advantages of small size, low cost, and low energy consumption in design and operation. We aim to provide an overview of microplasma detectors and show their applications in various chemical analyses. The operational characteristics and analytical performance of different microplasma detectors, such as capacitively coupled microplasma, glow discharge microplasma, and microhollow-cathode microplasma, are presented in detail to reveal the current status of microplasma detectors for gas chromatography. In addition, several approaches for the design of microplasma are discussed and the future trends in the development of microplasma detectors are highlighted at the end of this review. Various applications of microplasma detectors for gas chromatography systems are also presented in this review.

“…For this purpose, optical emission spectroscopy (OES) is combined with chromatography, in which a small amount of a liquid sample transferred by the electrophoresis effect in a capillary is taken into a micoplasma source, and the emission spectrum is analyzed for chemical constituents. In earlier days, a DC-discharge source with inner electrodes was used [52], but later ICP-type, coaxial type and microstrip-line type sources driven by high frequency power sources in a wide frequency range from RF to microwave have come to be used [53][54][55][56]. A micro-HC type DC source is also going to be used owing to its high plasma density [37,57].…”

Microscale plasmas of micrometer to millimeter range have been attracting much attention in recent years. Those microplasmas generally operate at high-pressure regions, including atmospheric pressure, and exhibit characteristics that differ from traditional plasmas at lower pressure regions in their plasma parameters and other parameters originating from their small dimensions. When those characteristics are well combined with the inherent properties of plasmas as reactive, light-emissive and conductive/dielectric media, there appear a variety of potential applications for nano-material syntheses, micromachining tools, microchemical analyses, photonic devices and biomaterial processing. In this article, the current status and perspective of microplasma research are reviewed from the viewpoints of plasma generation, diagnostics/simulations and new applications.

“…22–24 As a group, sensitivity was often tested using one gas or a similar series of halogen-containing hydrocarbons as the spectral lines for F, Cl, and Br are readily distinguished and spectrally remote. 20,24,25 Yet some studies have demonstrated detection of a series within the same family of compounds, e.g., alcohols. 23,26 Uniformly these plasmas have operated within an inert carrier gas.…”

An Investigation of Micro-Hollow Cathode Glow Discharge Generated Optical Emission Spectroscopy for Hydrocarbon Detection and Differentiation

The analytical utility of a micro-hollow cathode glow discharge plasma for detection of varied hydrocarbons was tested using acetone, ethanol, heptane, nitrobenzene, and toluene. Differences in fragmentation pathways, reflecting parent compound molecular structure, led to differences in optical emission patterns that can then potentially serve as signatures for the species of interest. Spectral simulations were performed emphasizing the CH (A(2)Δ-X(2)Π), CH (C(2)Σ-X(2)Π), and OH (A(2)Σ(+)-X(2)Π) electronic systems. The analytical utility of selected emission lines is demonstrated by a linear relationship between optical emission spectroscopy and parent compound concentration over a wide range, with detection limits extending down to parts per billion (ppb) levels.
