摘　　要：目提出了一种利用普通印刷线路板(Printed Circuit Boards,PCB)加工构造离子阱质量分析器的新方法。用该方法制造的PCB离子阱仅由四块PCB平板电极和两块不锈钢薄片电极构成,具有结构简单、加工容易和价格低廉等优点,非常适合制造成低成本的便携式质谱仪。初步实验结果表明,应用这种方法所建造的PCB离子阱质谱仪系统,可以获得优于400的质量分辨率和300Thomson以上的质量扫描范围。A novel method is proposed to construct an ion trap mass analyzer based on normal printed circuit board （PCB） fabrication technology. The PCB ion trap, consisting of four PCB electrodes and two metallic electrodes, has a simple structure and very low cost. A PCB ion trap mass spectrometer, including relevant vacuum system, electronic systems and ion detection devices, was designed and constructed based on the PCB ion trap and electron impact （EI） ion source. Samples such as carbon tetrachloride and toluene were used to characterize the instrument experimentally. Preliminary experiments demonstrated that the PCB ion trap has better than 400 mass resolution and higher than 300 Thomson mass range.
