Reconfigurable Transmission Direction Travelling-Wave Structure for Lossless Ion Manipulation
摘要
Abstract
Travelling wave structures for lossless ion manipulations(TW-SLIM)utilize travelling wave electric fields to drive ions forward,enabling ultra-long ion transmission paths and holding broad application prospects in ion transport and separation.However,in conventional TW-SLIM designs,the ion transmission direction cannot be altered once the device is fabricated,significantly limiting the flexibility of SLIM-based systems in complex applications.To address this issue,this study proposed a reconfigurable transmission direction TW-SLIM structure(RTDTW-SLIM).By functionally integrating and redistributing the guard electrodes,travelling wave electrodes,and radio frequency(RF)electrod from the conventional TW-SLIM layout,this architecture achieved lossless ion transport in multiple directions.Furthermore,through a reduction in the size of the guard electrodes,the overall structure was miniaturized,facilitating system integration.An experimental platform for RTDTW-SLIM was constructed,and experiments were conducted using dimethyl methylphosphonate(DMMP)as the target analyte.The results demonstrated that under optimized voltage configurations,the ion transmission efficiency could exceed 90%in different transmission directions.These findings verified the effectiveness of RTDTW-SLIM in achieving reconfigurable ion transmission pathways and provided a novel technical approach for its application in ion mobility spectrometry and the coupling of diverse ion analysis systems.关键词
