Abstract
Devices and methods for surface-induced dissociation (SID) are disclosed. In one aspect, a device for SID is disclosed which, in one embodiment includes a collision surface, a deflector configured to guide precursor ions from a pre-SID region to the collision surface to cause SID, and an ion carpet having applied electrical properties configured to guide product ions resulting from collision with the collision surface to a post-SID region. In another aspect, a method for SID is disclosed which, in one embodiment includes guiding, by a deflector, precursor ions from a pre-SID region to a collision surface to cause SID, and guiding, by an ion carpet having selected applied electrical properties, product ions resulting from collision with the collision surface to a post-SID region.
