Abstract
Systems, methods, and devices to dissociate ions using one or more light emitting diodes (LEDs). A mass spectrometer for ion dissociation includes an ion source for providing ions for dissociation, a mass analyzer, and a photodissociation (PD) device. The PD device includes an ion transport device. The ion transport device is configured perform one or more of: transporting the ions through the PD device, and trapping the ions within a region of the PD device. The PD device also includes one or more LEDs positioned to irradiate the ions in the PD device, resulting in fragmentation of the ions.
