Interpretive Summary:

Technical Abstract: With aggravation of environment pollution, elemental monitoring of environmental and food samples has attracted extensive attention. Microplasma-based optical emission spectrometry (OES) demonstrates great potential in the elemental field analysis due to its small size, low power consumption, and low cost. In this review, advances of portable/miniaturized OES systems using microplasma as excitation sources are reviewed, with emphasis on four aspects: microplasma excitation sources, sample introduction methods, hyphenated techniques, and their applications for real samples. Limitations and potential development trends are also discussed for portable microplasma-based OES, which will earn its place in field instrumentation development.
