| 摘 要： | 目的降低外界环境对离子迁移率的影响。方法讨论用标校物的IMS信号迁移时间对待测物质的IMS信号迁移时间进行校正的算法,通过对待测物质IMS信号进行修正,来减少外界环境的变化对IMS信号迁移时间的影响,提高探测的准确性,最后通过用空气作为标校物进行试验验证。结果迁移区电压的变化对IMS信号的影响降低了96%,迁移区温度的变化对IMS信号的影响降低了53%。结论该方法有效,为该校正技术在IMS信号处理中的应用奠定了基础。

| Abstract: | The paper aims to reduce the influence of external environment on ion mobility. In this paper, the algorithm of correcting the IMS signal migration time of the material to be measured by using the IMS signal migration time of the calibrator was discussed. By modifying the IMS signal of the material to be measured, the influence of the change of the external environment on the migration time of the IMS signal was reduced, and the accuracy of the detection was improved. Finally, the air was used as calibration object for verification. The influence of the voltage change in the migration zone on the IMS signal was reduced by 96%. The influence of the temperature in the migration zone on the IMS signal was reduced by 53%. This method is effective, which lays a foundation for the application of this correction technology in IMS signal processing. |
