Latest Patents

Grosshans' latest patents focus on methods and apparatus to control charge neutralization reactions in ion traps. One of his inventions involves an ion trap mass spectrometer that utilizes electrospray ionization to introduce multiply-charged positive ions in an axial direction into a quadrupole ion trap. Additionally, it employs glow discharge ionization to introduce singly-charged negative ions in a radial direction into the ion trap. His methods for controlling ion-to-ion charge transfer reactions include applying a combination of dipolar DC voltage and dipolar RF voltage across endcap electrodes. This allows for partial charge state neutralization reactions to occur between the positive and negative ions, enabling the suspension and resumption of further charge state neutralization reactions. The remaining ions can then be processed and transformed, leading to the creation of a mass spectrum by scanning a quadrupolar RF field.
