Title:
ANALYSIS METHOD FOR QUADRUPOLE ROD MASS ANALYZER
Document Type and Number:
WIPO Patent Application WO/2017/206965
Kind Code:
A1
Abstract:
An analysis method for a quadrupole rod mass analyzer, which belongs to the field of mass analysis. In the method, a higher quadrupole mass spectrum mass distinguishing capability is implemented by using a working voltage technology loaded on a quadrupole rod, that is, two AC excitation voltages are applied to the quadrupole rod in addition to a direct current (DC) voltage and a radio frequency (RF) voltage on a traditional quadrupole rod, and correspondingly an unstable band is generated at the top point of a stable region. Accordingly, a peak form is effectively optimized, and the reliability of mass distinguishing and measurement is improved. By scanning the stable band, the mass distinguishing of the quadrupole rod can exceed 10000 and has no substantial ion transmission loss.
