Micro-molecular spectrum identification device

Abstract

The invention discloses a micro-molecular spectrum identification device, comprising a box body, an ultraviolet visible near infrared circuit is arranged in the box body, the inner wall of one side ofthe box body is a spectrum sampling window, the near infrared spectrum sampling window is provided with a near infrared spectrum sensor, a visible light spectrum sensor, an ultraviolet spectrum sensor and an ultraviolet visible near-infrared LED light source which are connected with the ultraviolet visible near infrared circuit; the opposite side of the infrared spectrum sampling window is windowglass capable of transmitting ultraviolet visible near-infrared light, and an integral cavity is formed in the middle. The window glass is pressed on a sample, and the surface of the sample can be flattened by the window glass, so that the sampling quality is improved. After flattening, the ultraviolet visible near-infrared LED light source emits light beams to be directly emitted or reflected tothe surface of the sample through the inner wall of the integral cavity, the light beams emitted by the ultraviolet visible near-infrared LED light source are absorbed by the sample irradiated by theultraviolet visible near-infrared light, and then, the light passes through the ultraviolet visible near-infrared window glass to be received by the spectral sensor to form a spectrum.

Description

technical field [0001] The invention relates to the technical field of molecular spectroscopy, in particular to a miniature molecular spectroscopy identification device. Background technique [0002] Near-infrared spectral analysis technology is a rapid detection technology that uses chemometric methods to analyze the near-infrared spectrum of objects, and can conduct qualitative and quantitative analysis of the chemical main components and physical form information of objects. Near-infrared spectroscopy technology has the excellent characteristics of no need for sample preparation, non-destructive, rapid and simultaneous detection of multiple indicators. As an alternative to traditional physical and chemical analysis techniques, it has been widely used in the manufacturing field. The main purpose of near-infrared spectral analysis is to extract the response of physical and chemical information of different objects to the absorbance of near-infrared light, and then use the d...
