Description

Fixing device for Raman spectrum collection of spherical fruit and vegetable samples

Technical Field

The utility model relates to a raman spectroscopy detects technical field, relates to a fixing device of spherical fruit vegetables sample is gathered to raman spectroscopy.

Background

Based on the raman scattering effect, a raman spectrometer is used to study the spectrum of light scattered by a sample, so as to detect the structure of the sample and obtain various physical and chemical information of the sample, and the method for obtaining the structure and related information of the sample is called as a raman spectrum detection technology.

In recent years, the raman spectroscopy detection technology has become one of the research hotspots in the detection and analysis field due to its advantages of rapidness, high sensitivity, nondestructive detection, etc., and is widely applied to the fields of food detection, drug detection, jewelry identification, etc. When a Raman spectrum signal of a sample is collected, in order to improve the effectiveness and reliability of the signal, the sample needs to be fixed to prevent the sample from sliding, but the number of sample fixing devices for collecting the Raman signal at present is small, so that the Raman spectrum data collection of the sample is restricted to a certain extent, and particularly for a spherical sample which is easy to slide and is not easy to fix, the sample fixing requirements during the Raman spectrum collection are higher.

SUMMERY OF THE UTILITY MODEL

In view of the not enough of prior art, the utility model aims to provide a fixing device that spherical fruit vegetables sample raman spectrum gathered aims at solving among the prior art not good fixed position when the spherical fruit vegetables sample of raman spectrum collection, influences the problem of data accuracy.

Based on above technical problem, the utility model discloses the technical scheme who adopts does: the utility model provides a fixing device that spherical fruit vegetables sample raman spectrum gathered, include: a base; the arc-shaped sample cell seat is arranged on the base; the button with the adjustable position is arranged on the arc-shaped sample pool seat and used for positioning a sample in the arc-shaped sample pool; the adsorption module is used for increasing the overall stability of the device; and the fixing module is used for quickly and accurately connecting the arc-shaped sample cell seat with the base.

Above-mentioned fixing device that spherical fruit vegetables sample raman spectrum gathered is equipped with the absorption module bottom the base, can firmly hold the mesa, makes fixing device more firm. The positioning module is arranged on the base, so that the arc-shaped sample cell holder can be quickly fixed on an ideal position of the base, can be detached to save space, and improves the detection efficiency and the space utilization rate. The arc sample cell seat is arranged on the base, the spherical fruit and vegetable samples to be tested are arranged on the arc sample cell, and the rolling of the spherical fruit and vegetable samples arranged on the arc sample cell seat can be reduced to a certain degree due to the fact that the arc sample cell seat has a certain radian. The button of adjustable position can move and must set up on arc sample cell seat, realizes fixing spherical fruit vegetables sample through adjusting the button of adjustable position.

The utility model discloses relative prior art's advantage is: the conventional Raman sample table cannot well fix spherical fruit and vegetable samples, and when Raman spectra of the spherical fruit and vegetable samples are collected, the samples often roll to enable sample points for collecting Raman spectrum data to shift, so that the reliability and effectiveness of the obtained data are insufficient. The fixing device of the utility model has exquisite and reasonable appearance, is convenient to assemble and disassemble, the base is made of metal materials, the chassis is stable, and the bottom of the base is provided with the adsorption module, so that the fixing device is more stable to be placed on a smooth horizontal table top; the arc-shaped sample pool seat reduces the rolling of spherical fruit and vegetable samples which are easy to roll to a certain extent, the buttons with adjustable positions can quickly and accurately fix the spherical fruit and vegetable samples, and the spherical fruit and vegetable samples can be effectively prevented from rolling when Raman spectra are collected, so that the collected Raman spectrum data are more reliable and effective.
