| 主权项 | 1. A mass spectrometry system, comprising: an ion source; an ion trap; an ion detector; and an electronic processor connected to the ion source, the ion trap, and the ion detector, and configured to operate the ion source and ion trap in at least two ionization modes during a survey time period of 500 ms or less, wherein in a first ionization mode of the at least two ionization modes, the electronic processor is configured to operate the ion source to generate a plurality of positively charged ions from sample molecules or particles in the system; and wherein in a second ionization mode of the at least two ionization modes, the electronic processor is configured to operate the ion source to generate a plurality of negatively charged ions from sample molecules or particles in the system. | ||
