ION EXTRACTION AND FOCUSING FROM A FIELD-FREE REGION TO AN ION MOBILITY SPECTROMETER AT ATMOSPHERIC PRESSURE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240044840 titled 'ION EXTRACTION AND FOCUSING FROM A FIELD-FREE REGION TO AN ION MOBILITY SPECTROMETER AT ATMOSPHERIC PRESSURE
Simplified Explanation
The patent application describes an apparatus that includes a series of electrodes arranged in a specific sequence to create an electric field that guides ions along a defined path. The electrodes receive different voltages to generate the electric field, which propels the ions towards an ion outlet. The sequence of electrodes includes a first and last electrode that receive voltages according to a specific function, and at least one intermediate electrode that receives a voltage dip relative to the first function.
- The apparatus includes a series of electrodes that create an electric field to guide ions along a specific path.
- The electrodes receive different voltages to generate the electric field.
- The sequence of electrodes includes a first and last electrode that receive voltages according to a specific function.
- At least one intermediate electrode situated between the first and last electrodes receives a voltage dip relative to the first function.
