Ion trap array for high-throughput charge detection mass spectrometry

摘要

An electrostatic linear ion trap (ELIT) array comprises a number of elongated charge detection cylinders, each defining an axial path that is arranged end-to-end and extends through the center, a pair of axially aligned cavities and a center extending through the center. A plurality of ion mirror structures each defining an axial passage, a different ion mirror structure disposed between both ends of each cylinder, and a front surface each defining an axial passage extending through at least one cavity and a center, and A rear ion mirror, wherein the front ion mirror is disposed at one end of the array of charge detection cylinders and the rear ion mirror is disposed at the opposite end of the array of charge detection cylinders, wherein the charge detection cylinder, ion mirror structure, front ion mirror and The axial passage of the rear ion mirror is coaxial to define a longitudinal axis passing from the center through the ELIT array.
