Abstract:

In an ion cyclotron resonance mass spectrometer, ion cyclotron resonance signals at higher harmonics of cyclotron frequency are employed to increase the resolution of ICR mass spectrometer without increasing the magnetic field. The detection electrodes consist of M (where M is an integer) identical electrodes arranged in M-fold symmetry about the axis of the coherent cyclotron motion of the observed ions. In an ion cyclotron having four points of voltage in space, the cyclotron electrodes are set up in clockwise symmetric fashion. To increase the resolution in signal detection resulting from the potential induced by ions moving in orbits in the specrometer, the first and third voltages are added and the second and fourth voltages are subtracted from the sum of the first and third voltages.

Abstract:

A container is provided in the present disclosure. The container includes at least one outer wall that is made of a low temperature tolerant material where the at least one outer wall is arranged to substantially form the container with an opening end; a tube that is situated inside the at least one outer wall, where the tube and the at least one outer wall are substantially thermally insulated, and the tube is open at one end that is on a same side of the opening end of the container; and a container cover being shaped substantially to match the at least one outer wall, where the container over is capable of covering the opening end of the container.
