WebThe results showed that SPCA can significantly improve the signal-to-noise ratio and hence lower the detection limits (∼0.389% g/mL for mannitol−methanol suspensions and 0.4 wt … WebAbstract. While the resolving power of drift tube ion mobility spectrometers has been studied and modelled in detail over the past decades, no comparable model exists for the signal-to-noise-ratio. In this work, we develop an analytical model for the signal-to-noise-ratio of a drift tube ion mobility spectrometer based on the same experimental ...
