Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] In the following description, a lot of specific details are set forth in order to fully understand the application, but the application can also be implemented in other ways different from those described here, and those skilled in the art can do without violating the connotation of the application. By analogy, the present application is therefore not limited by the specific embodiments disclosed below.

[0028] As mentioned in the background technology section, the mass spec...

Abstract

The embodiment of the invention discloses an infrared light dissociation spectrometer device. The infrared light dissociation spectrometer device comprises an ion source, a mass spectrum component anda light spectrum component; the ion source is used for generating preset ions; the mass spectrum component is used for screening out a specific ion from the preset ions; and the light spectrum component is used for acquiring a spectrum chart of the specific ion. The mass spectrum component replaces the time-of-flight mass spectrum system by a hyperbolic linear ion trap system, thereby greatly reducing the size of the mass spectrum component, and further reducing the size of the infrared light dissociation spectrometer device, so that the infrared light dissociation spectrometer device is easyto carry for external field experimental observation.

Description

technical field [0001] The present application relates to the field of spectroscopy technology, in particular to an infrared photodissociation spectrometer device. Background technique [0002] Characterizing the geometric structure, energy level structure and chemical reactivity of particles (such as gas phase ions, clusters, etc.) is one of the most active research directions in molecular reaction dynamics. These studies involve the most fundamental issues such as the nature of chemical bonding, chemical reactions, and energy redistribution within reaction systems. [0003] Spectroscopy methods based on laser technology are very efficient experimental methods for determining properties such as molecular structures. Among them, infrared spectroscopy is the most effective method to obtain the gas phase particle structure. Since most gas-phase compound molecules or ions have infrared absorption and have characteristic absorption peaks, through infrared spectrum analysis, th...
