SAMPLING HEAD, SAMPLING SYSTEM, MASS SPECTROMETRY IMAGING DEVICE, AND SAMPLING METHOD

WIPO Patent Application WO/2021/139406

A1

A sampling head, a sampling system, a mass spectrometry imaging device, and a sampling method. The sampling head comprises a sampling body (100), a tenon (601, 701) being provided on one of two opposite sides of the sampling body (100), and a mortise (602, 702) having a size matching the tenon (601, 701) being provided at an opposite position on the other side; a sampling cavity (200) arranged on a first end face (102) of the sampling body (100), wherein the sampling cavity (200) and a surface being sampled form a sampling region; a first flow channel (300) for injecting an extractant; and a second flow channel (400) for injecting air, and a third flow channel (500) for exporting sampling droplets. Since the sampling head is in direct contact with the surface being sampled, sampling can be implemented without exsomatization. The method of droplet extraction does not cause injury to the surface being sampled. The sampling cavity (200) is close to the surface being sampled, thereby improving the concentration of sampling droplets, which reduces the possibility of missing key compound information, and thus improves the quality of sampling.
