Embodiment Construction

[0043] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0044] As a sustainable energy source, triboelectric nanogenerator (TENG) can convert mechanical energy in the environment into electrical energy. A triboelectric nanogenerator (TENG) consists of two electrodes and at least one pair of triboelectric material layers. The relative mechanical movement between these friction layers breaks the initial electrostatic balance, and the induced charge is redistributed on the electrodes, thus generating an output of charge in the external circuit. The application of TENG in self-propelled systems demonstrates its great application prospects in the fields of biomedical science and personal electronic devices. Based on tri...

Abstract

The invention provides an ion source device, a method for generating an ion pulse, application of ion source devices in material analysis, material deposition and / or surface processing and a mass spectrometer. The device comprises a friction nanometer power generator and an ion source, wherein the friction nanometer power generator provides a power supply for the ion source. Ion pulses with unipolarity or positive polarity and negative polarity which are alternative can be generated by a high output voltage of the friction nanometer power generator, and total ionization charge is quantitatively controlled in a mass spectrometry system; during the analysis process, the definition is high, and the duration time, the pulse frequency and the polarity of spraying ions all can be adjusted; and moreover, the consumption of a sample can be reduced to the lowest extent. The device can be used for analyzing various chemical constituents, and natural protein conformation can be stored very well.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an ion source device for an analytical instrument, a method for generating ion pulses, and its application in material analysis, material deposition and / or surface treatment, and a mass spectrometer. Background technique [0002] Due to the high sensitivity and insurmountable molecular uniqueness of mass spectrometer, it is a key analytical tool in various fields such as biomedicine, food science, systems biology, and drug identification. As a link before mass spectrometry, it is necessary to add a voltage to the ion source (this voltage is usually used as the basic standard parameter) to convert neutral substances into gas phase ions. However, the amount of ions generated in this process does not have a direct relationship with the applied voltage value, because the ion source in the molecular mass spectrometry system is usually powered by a DC power supply, and the user cannot contr...
