| 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. |
