Title:
EIGHT-ELECTRODE LINEAR ION TRAP MASS ANALYZER
Document Type and Number:
WIPO Patent Application WO/2019/095727
Kind Code:
A1
Abstract:
Provided is an eight-electrode linear ion trap mass analyzer, formed by eight columnar electrodes and at least two end cap electrodes: the inner surface of the eight columnar electrodes is arbitrary in shape; the material of the eight-electrode linear ion trap mass analyzer is a conductive metal material or an insulating material plated with a conductive coating; every two columnar electrodes is in one group, and there are a total of four groups of columnar electrodes, which are placed with every two being in parallel with each other; and at least one through hole is provided in the center of the end cap electrode, and the two end cap electrodes are respectively arranged at the two ends of the columnar electrode. According to the prevent invention, a traditional four-electrode structure is replaced with an eight-electrode structure, so that the working voltage is applied in a more flexible manner, and more new functions can be achieved.
