With concerns increased for environmental pollution and human health, monitoring elemental levels in various real world samples has been frequently performed via laboratory-scale atomic spectrometers or mass spectrometers. However, their large size, high power consumption and complicated operation disable fast and field analysis. 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 applications for samples analysis. Limitations and potential development trends are also discussed for portable microplasma-based OES, which will earn its place in field instrumentation development.

用于元素分析的基于微等离子体的小型化便携式发射光谱仪研究进展

随着对环境污染和人类健康的关注日益增加,人们经常通过以下方式监测各种真实世界样品中的元素水平实验室级原子光谱仪或质谱仪。然而,它们体积大、功耗高、操作复杂,无法进行快速和现场分析。基于微等离子体的光学发射光谱法 (OES) 由于其体积小、功耗低和成本低而在元素场分析中显示出巨大的潜力。在这篇综述中,回顾了使用微等离子体作为激发源的便携式/小型化 OES 系统的进展,重点介绍了四个方面:微等离子体激发源、样品引入方法、联用技术和样品分析应用。还讨论了基于便携式微等离子体的 OES 的局限性和潜在的发展趋势,这将在现场仪器开发中占有一席之地。
