To achieve a highly sensitive and onsite analysis of a small amount samples, a microplasma-based micro total analysis systems (μ-TAS) device was developed. A dielectric barrier discharge (DBD) that can generate a stable plasma at atmospheric pressure was generated in a microchip and used as the plasma source. The use of DBD suppresses the temperature rise of the electrodes and enables operation for long times because of a reduction of the electrode damage due to suppression of the current via dielectric interposing between the electrodes. It is expected that the analytical system can be miniaturized because helium plasma is generated in the microchannel contained in the microchip. Emissions from gaseous Cl, Br, and I were analyzed using the plasma source, and it was found that the detection limits for these analytes were 0.22, 0.18, and 0.14 ppm, respectively. The calibration curves for gaseous Cl, Br, and I were also plotted obtaining correlation coefficients of 0.975, 0.955 and 0.986, respectively, and showing good linearity for the developed plasma source.

“…One paper has reported a miniaturized atomic emission detector with picolitre sample introduction by an inkjet microchip. 115 The finger-sized atomic emission detector used a helium RF plasma and the performance of this detector was evaluated for Cl determination using 1,1,1-trichloro-2-methyl-2-propanol dissolved in isopropanol. The ejection volume of one droplet from the inkjet microchip was calculated as 463 pl, (5100 droplets were 2.36 AE 0.04 ml (n = 5)).…”

“…A compact elemental analysis system was developed in Japan, 245 incorporating an inkjet microchip for sample injection, a helium rf plasma and a ''finger-size'' atomic emission detector. The performance of the system was evaluated with 1,1,1,-trichloro-2-methyl-2-propanol (chloretone) dissolved in isopropanol as the sample.…”
