AI Technical Summary
Technical Problem
Existing mass spectrometers use a method of applying bacteria to a metal plate using cotton swabs or toothpicks, requiring sampling for each test, resulting in slow loading efficiency and failing to meet usage requirements.
Method used
A sample feeder for mass spectrometer testing was designed, comprising a housing, a sample feeding structure, a sample core, and a cutting structure. The sample core is moved by a rotating head driving a threaded rod and a slider, and the sample core is cut by a cutting blade, enabling multiple sampling operations.
Benefits of technology
It improves sample loading efficiency, facilitates multiple sampling, meets practical needs, and enhances the sample loading efficiency of the mass spectrometer.

Abstract
This utility model belongs to the field of mass spectrometer testing technology, and discloses a sample feeder for mass spectrometer testing, including a shell with a gripping part in the middle; a sample feeding structure disposed inside the shell for sample feeding; a sample core disposed on the sample feeding structure and located inside the shell; and a cutting structure disposed inside the shell for cutting the sample core. A cylindrical groove is formed inside the shell, and multiple arc-shaped slots are formed on the inner wall of the cylindrical groove, arranged in a circumferential array. The sample feeding structure is located within the cylindrical groove and the arc-shaped slots. A threaded hole is formed on the inner side wall of the cylindrical groove, and the sample feeding structure is located within the threaded hole. The sample feeding structure includes a cylindrical slider, which is slidably connected to and adapted to the inner cavity of the cylindrical groove. Multiple arc-shaped blocks are integrally formed on the outer surface of the cylindrical slider. This utility model not only facilitates sample feeding but also has high efficiency and meets practical application requirements.
