Handheld Microplasma Optical Emission Spectrometer Coupling With Self-Heating Solid-Phase Microextraction For On-Site Detection Of Urinary Lead

“…To solve these problems and improve analytical performance, the MP-OES has been coupled with many sample introduction techniques, including cold vapor generation, 22 hydride generation, 18 photochemical vapor generation, 23 tungsten coil (Wcoil) electrothermal vaporization, 24,25 and solid-phase microextraction (SPME). 21,[26][27][28] These sampling approaches can efficiently separate analytes from liquid phase as "dry" species before their exposure to microplasma, significantly enhancing the MP-OES sensitivity and alleviating matrix interferences.…”

“…However, for field analysis, only sample introduction and detection are often focused on, and sample pretreatment in the field is ignored. As a result, most microplasma OES methods and devices are suitable for field analysis of environmental water samples instead of biological samples. − Although direct determination of heavy metals in biological samples can be achieved by electrothermal/electromagnetic heating vaporization, − the treated sample amount (0.15–20 mg) is very small, ,, leading to a higher detection limit. In addition, this method can only treat one sample at a time, greatly limiting the analytical throughput, and the high heating power makes it difficult to achieve long-term battery power, so it is still limited in field analysis.…”
