Microplasma-Based Detectors for Gas Chromatography: Current Status and Future Trends

Abstract

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.

Low temperature co-fired ceramics plasma generator for atmospheric pressure gas spectroscopy

“…However, the relatively low pressure on the generator operation significantly limits its possible application for gas characterization. Increasing attention has recently been put on gas chromatography based on optical emission spectrometry [25]. In our work, we present preliminary works on a miniature LTCC-based plasma generator for gas spectroscopy, which utilizes discharge in gas at atmospheric pressure.…”
