Abstract
A novel system and methods for accelerating analytes including, without limitation, molecular ions, biomolecules, polymers, nano- and microparticles, is provided. The invention can be useful for increasing detection sensitivity in applications such as mass spectrometry, performing collision-induced dissociation molecular structure analysis, and probing surfaces and samples using accelerated analyte.
Claims21
An apparatus comprising:
- a. a source of ionized analyte;
- b. a linear pulsed-voltage acceleration subsystem;
- c. at least one power supply and at least one function generator connected to the pulsed-voltage acceleration subsystem;
- and
- d. an ion detector;
- wherein the apparatus is configured to accelerate the ionized analyte linearly from the source to the detector, and wherein the detector is located at the end of the accelerator flight path.
3 more elements
A linear pulsed-voltage ion acceleration apparatus comprising:
- a linear series of from 5 to 1000 electrodes, wherein the electrodes are plates, cylinders or boxes;
- a series of three or more function generators, wherein each function generator is independently connected to one or more of the electrodes;
- wherein the apparatus is configured to accelerate a singly-charged ion to an energy of up to 10 MeV.
