The JEOL JMS-SX102/SX102A/E is a one of a kind mass spectrometer. The instrument consists of two SX102 double-focussing instruments followed by a JEOL HX110 ESA. The SX102 is a reverse geometry instrument(BE). The SX102 is capable of resolving powers >60,000 and has a mass range of 2,500 at 10kV accelerating voltage. MS1 has electron ionization(EI), chemical ionization, fast atom bardbardment (FAB), continues flow FAB, and electrospray ionization (ESI) ionization capabilities. MS2 has EI and FAB ionization capabilities, but this source is typically used for calibration of MS2 only. The unique geometry of the JEOL JMS-SX102/SX102A/E provides for the ability to analyze the products of dissociation up to the 5th generation products. An important feature of this instrument is that all of the field-free regions of the spectrometer have easily removable collision cells. This feature allows for the study of metastable dissociations and collision induced dissociation reactions. The HX110 ESA is used for studies of the kinetic energy released upon fragmentation of an ion. The kinetic energy release provides information about the potential energy surface of the reaction.
