“…ICP simulation based on COMSOL has been widely used and studied at home and abroad, which mainly involves the design optimization of ICP source, plasma physics, surface treatment, spectral analysis, and other aspects. With the continuous development of science and technology, ICP-based simulation will play an increasingly important role in the design and application of ICP sources [6,7] .…”

By studying the basic principle of ICP and the characteristics of low-temperature plasma, the advantages of using a plasma metal cylinder discharge chamber are discussed, and the influence of skin effect on discharge effect is deeply investigated. COMSOL multi-physics finite element software is used to analyze the physical characteristics of the sensitively coupled plasma. The results show that COMSOL has high feasibility and accuracy in numerical simulation of the perceptualcoupled plasma, which provides theoretical and technical support for the application of plasma in material processing, environmental purification, and other fields.

“…These kinds of herbicides are used in isolation or in combination during the period of rice crops' growth, resulting in the same effect as weeding [2]. However, herbicide residues are a universal phenomenon in agricultural production, where the process of spraying herbicides may lead to the absorption of herbicides into crops, resulting in indirectly effects on human health [1,3,4]. Due to the abuse of these herbicides, their residues have been found in rice crops and the surface water near rice paddies, which had concentration ranges of 5-270 µg/kg and 0.2-340 ng/L, respectively, creating a threat to health.…”

Abuse of herbicides in food safety is a vital concern that has an influence on the sustainable development of the world. This work presents, a modified ionization method with separation of the sample and carrier gas inlets, which was utilized for efficient ionization and analyte transfer of herbicides in crops. The working parameters of voltage, injective distance, desorption temperature, and the carrier gas flow rate were optimized to achieve the high efficiency of the transfer and ionization of the analyte. When it was applied in the analysis of herbicides in laboratory, the method exhibited excellent performance in achieving the quantitative detection of herbicides in solutions and residues spiked in an actual matrix with a limit of quantification of 1–20 μg/kg and relative standard deviations of less than 15%. Although a simple QuEchERS process was used, the programmable heating platform ensured efficient gasification and transfer of the target analyte, with the advantages of high speed and selectivity, avoiding the noted matrix effect. The method exhibited a relatively acceptable performance by using air as the discharged gas (open air). It could be used to monitor herbicide residues in the growth stage via on-site non-destructive analysis, which obtained low LODs by dissociating the herbicides from the crops without any pretreatment. It showed great potential for the supervision of the food safety market by achieving non-destructive detection of crops anytime and anywhere. This finding may provide new insights into the determination of pesticide emergence and rice quality assessment.
