Abstract
The application provides a mass spectrometry device and method based on a composite ion source, which comprises a mass spectrometer with a mass spectrometry inlet; the first central axis of the first outlet of the first ion source and the second central axis of the mass spectrometry inlet form an acute angle, and the first central axis enters the mass spectrometry inlet unobstructed; the first ion source adopts an electrospray ion source; the third central axis of the second outlet of the second ion source is parallel to the second central axis, and the third central axis enters the mass spectrometry inlet unobstructed; the second ion source adopts a pulsed direct current electrospray ion source; the first distance between the first outlet and the inlet is greater than the second distance between the second outlet and the inlet. The application realizes the quick switching of multiple working modes.
