Abstract
An apparatus for detecting constituents in a sample includes first and second drift tubes defining first and second drift regions, and a controllable electric field device within a fragmentation region coupled to the first and second drift tubes. The apparatus also includes a first ion shutter positioned between the first drift and fragmentation regions. The apparatus further includes a control system configured to regulate the first ion shutter, thereby facilitating injection of a selected portion of ions from the first drift region into the fragmentation region. The control system is also configured to regulate the controllable device to modify the selected portion of ions to generate predetermined ion fragments within the fragmentation region, thereby facilitating injection of a selected portion of the predetermined fragmented ions into the second drift region. A method of detecting constituents in a sample is facilitated through such an apparatus.
