Abstract: This invention relates to systems and methods of optimizing the control and performance of Laser Desorption and Ionization (LDI) ion sources or Electro Spray (ES) ion sources employing electro-pneumatic superposition, the ion sources being operably connected to a mass spectrometer. Methods and systems of control include analyzing data from the mass spectrometer during its operation, generating signals from the data analysis, and providing the signals as feedback to control the operation of the ion source. Data from which informative feedback signals are generated may include the mass spectrum data from a sample being analyzed, and may also include data from sensors providing conditions of the ion source during operation.

Abstract: The invention provides apparatus and methods for controlling ion current in an ion transmission device. An apparatus of the present invention comprises an ion source, an ion transmission device, and a controller. The ion source and the ion transmission device are in ion communication therebetween, and the controller is in signal communication with both the ion source and the ion transmission device. The ion current of the ion transmission device may be controlled by coordinating at least one of the operating parameter values of the ion source with at least one of the operating parameter values of the ion transmission device. Such coordination may result in, for example, improved ion current in the ion transmission device. Also embraced by the present invention are mass spectrometer embodiments that include or use the apparatus or methods of the present invention for controlling ion current.

Abstract: A cell-quadropole cell structure is disclosed which extends the principle of sharing the bitline-stud between two different cells (arranged in a one-dimensional line, e.g. w-direction) further to the maximal possible degree of a sharing in a two-dimensional area (x- and y-direction) consequently forming a cross of four cells around one bitline-stud with each drain region and buried strap extended to the side and the trench attached forming a hook like structure.
