摘要：随着质谱检测技术应用领域不断扩大，质谱仪正朝着小型化、便携式方向发展。针对应急快速检测场景对质谱仪便携性的需求，提出一种小型化的极板形四极杆质量分析器，并设计了极板的宽度、厚度等参数。利用多物理场耦合分析软件分析极板的宽度、厚度对离子传输效率的影响；探究在宽质量范围（10~150 amu）内马修参数a、射频频率f、离子入射能量E对极板形四极杆质量分析器离子传输效率的影响。仿真结果显示：当质荷比为40 amu时，随着极板宽度增加，离子传输效率增大；在宽质量范围（10~150 amu）内，采用极板宽度W为10.5 mm、极板厚度H为2 mm、马修参数a为0.17、射频频率f 为1.6 MHz、离子入射能量E为4 eV的最优参数组合时，极板形四极杆质量分析器的离子传输效率均达到80%以上，可满足环境、土壤重金属等快速质谱检测的需求。

Abstract: As the application fields of mass spectrometry continue to expand, mass spectrometers are increasingly moving toward miniaturization and portability. To meet the portability requirements of mass spectrometers for rapid on-site detection scenarios, a miniaturized plate-type quadrupole mass analyzer is proposed, and parameters such as plate width and thickness are designed. A multi-physics coupling simulation software is used to analyze the influence of plate width and thickness on ion transmission efficiency. The effects of the Mathieu parameter a, radio frequency f, and ion injection energy E on the ion transmission efficiency of the plate-type quadrupole mass analyzer over a wide mass range (10-150 amu) are investigated. Simulation results show that for a mass-to-charge ratio of 40 amu, the ion transmission efficiency increases with increasing plate width. Within the wide mass range (10-150 amu), using the optimal parameter combination of plate width W = 10.5 mm, plate thickness H = 2 mm, Mathieu parameter a = 0.17, radio frequency f = 1.6 MHz, and ion injection energy E = 4 eV, the ion transmission efficiency of the plate-type quadrupole mass analyzer reaches above 80%. This performance meets the requirements for rapid mass spectrometry detection in applications such as environmental and soil heavy metal analysis.
