Optimizing field type four pole rod

Abstract

Tetrapolar pole for optimizing shape of field can be in use as pole type analyzer for mass of ion, ion trap type analyzer for mass of ion, linear ion trap, or ion guidance. The tetrapolar pole includes at least four RF electrodes parallel to z-axis of central axis of mass analyzer, and RF voltage of generating RF ion capture electric field. Here, RF electrodes are in structure of cylinder body. The cylindrical surface is locus drawn out by generating line L of electrode parallel to z-axis, and moving along the gauge line of electrode f(x,y)=0. The locus possesses form of piecewise function. Using a set of parallel plane through each boundary point, the invention parses x or y electrode into at least two thin layer. It is easy to be produced for the electrode possible to be parsed to multiple units of thin layer. Adjusting parameters of the thin layers can obtain optimized shape of tetrapolar field so as to improve analytical performance of tetrapolar mass analyzer.

AI Technical Summary

Benefits of technology

This new method described by Currie et al describes how optimizing the design for optimal electric filed distribution within specific areas on a device called a quadrantium (Q) ion trap used in mass spectrometry analysis. By dividing up some parts of these devices into smaller sections and create them from simpler shapes like planar plates or circular discs instead of complicated ones made entirely out of metal, it allows for more precise control over electrically charged particles during experiments. Overall, this technology makes analyzers better at identifying unknown materials even when they have complex structures inside their cavities.

Problems solved by technology

Technologies described include various technical featments related to miniaturized devices called quadrplet ion counters (QIC). QISCs use multiple smaller circularly polarizable elements instead of traditional ones like hexapods, while QIMS utilizing triplex structures allows for more precise control over particle motion within these instruments. Additionally, there exist techniques for improving the performance of Quadrel Ion Time Spectrum Analysators (qIT) due to their ability to accurately analyze complex mixtures containing many different types of particles without requiring expensive precision machine tools.
