An ion trap chip and a system are disclosed, and are applicable to the field of quantum computing. The ion trap chip includes: a plurality of first ion traps (10), each configured to store an operation ion, where two adjacent first ion traps (10) form one ion trap group (30); and a plurality of second ion traps (20), where the second ion trap (20) corresponds to one ion trap group (30), and the second ion trap (20) is configured to perform quantum operations of operation ions (101) stored in the corresponding ion trap group (30). The second ion trap (20) is located between two first ion traps (10) in the corresponding ion trap group (30). The operation ions (101) stored in the first ion traps (10) in the ion trap group (30) are transported to the corresponding second ion trap (20) along a straight line. In the ion trap chip, an ion storage area and a quantum operation area are separated, and the ion storage area and the corresponding quantum operation area are located in a same straight line, so that ion transport does not require a turning. This greatly improves quantum computing efficiency.

The invention generally relates to systems and methods for analyzing operational status of an electronic instrument. In certain embodiments, the invention provides systems that include a sampling module that operable couples to an electronic instrument in a manner that the sampling module receives a vapor emitted from the electronic instrument, the sampling module comprising an ionization source and one or more mass analyzers to thereby produce a chemical signature of one or more analytes in the vapor; and an analysis module operable coupled to the sampling module to receive the chemical signature of the one or more analytes in the vapor and compare the received chemical signature to a database of known chemical signatures to thereby determine operational status of the electronic instrument.

What is disclosed herein are quadrupole mass filters (QMF) and related methods. The QMFs may have a relatively high surface roughness and / or be additively manufactured, wherein the QMF may be configured for ion filtering in a mass spectrometer. The methods may comprise: a. applying transverse sections to produce a dielectric part; b. masking one or more surfaces of the dielectric part to produce a partially masked dielectric part; c. positioning a metal on the partially masked dielectric part with a metal conductor to produce one or more electrically conductive surfaces on the printed part; and d. removing the mask from the printed part to produce a finished QMF; wherein the QMF is configured for ion filtering in a mass spectrometer.

The invention generally relates to sample analysis with a miniature mass spectrometer. In certain embodiments, the invention provides methods that involve generating ions of a first analyte and ions of a second analyte. Those ions are transferred through a discontinuous sample introduction interface into a first ion trap of a mass spectrometer in a manner in which the discontinuous sample introduction interface remains open during the transferring. The discontinuous sample introduction interface is closed and the ions are sequentially transferred to a second ion trap of the mass spectrometer where they are sequentially analyzed.
