Embodiment 1

[0034] Such as Figure 1~3 As shown, a sample sealing tube for protecting air-sensitive samples includes a sample loading tube 11 and an auxiliary device 12 matched with the sample loading tube 11; one end of the sample loading tube 11 is connected with the auxiliary device 12, and the The other end is used to hold the sample; the wall thickness of the sample loading tube 11 is 5-50 μm.

[0035] Further, the wall thickness of the sample loading tube 11 is 5-50 μm. Preferably, the wall thickness of the sample loading tube 11 is 10-30 μm. More preferably, the wall thickness of the sample loading tube 11 is 20 μm. Through a large number of product experiments, the present inventor found that the sample loading tube 11 can be used to prepare the sample sealing tube 1, and the use of the sample loading tube 11 for sample loading will not affect the diffraction experimental data, especially for single crystal diffraction testing. Experiment; at the same time, the sample loading t...

Embodiment 2

[0042] A preparation method for a sample sealing tube for protecting air-sensitive samples, comprising the following steps:

[0043] S1. Prepare a sample loading tube 11 with a tube wall thickness of 5-50 μm and an auxiliary device 12 matching the sample loading tube 11;

[0044] S2, connecting one end of the sample loading tube 11 to the auxiliary device 12, specifically, inserting one end of the sample loading tube 11 into a microsyringe, and then performing single crystal sample loading after the stable connection;

[0045] S3, after the single crystal sample loading is completed, the sample loading tube 11 is firstly removed from the auxiliary device 12, and the two ends of the sample loading tube 11 are sealed;

[0046] The preparation method is simple and easy to operate. Although the diameter and wall of the tube used are smaller and thinner, compared with the capillary tube purchased regularly, the sample sealing tube 1 of the present invention is more suitable for the...

Embodiment 3

[0048] An application of a sample sealing tube for protecting air-sensitive samples in an X-ray diffraction test experiment, the sample sealing tube 1 is the sample sealing tube 1 described in Example 1. Among them, the most effective one is used in the X-ray single crystal diffraction test experiment.

Abstract

The invention provides a sample sealing tube for protecting an air sensitive sample. The sample sealing tube comprises a sample loading tube and an assistor matched with the sample loading tube, one end of the sample loading pipe is connected with the assistor, and the other end of the sample loading pipe is used for containing a sample; and the thickness of the tube wall of the sample loading tube is 5-50 mu m. Compared with the prior art, the thickness of the tube wall of the sample loading tube adopted by the invention is proper, the situation that the tube wall is usually broken due to toothin thickness is avoided, and the quality of diffraction data is not influenced due to too thick tube wall. According to the sample sealing tube, sample preparation operation is easier and more flexible than that of an existing glass capillary tube, the sample loading sealing tube can be prepared at any time according to experimental requirements, and the problems that an existing capillary tubeis not easy to prepare, the wall thickness is difficult to control, and the capillary tube cannot be well applied to capillary tube sealing sample loading are solved. In addition, the invention alsoprovides a preparation method and application of the sample sealing tube.

Description

technical field [0001] The invention relates to the technical field of diffraction testing, in particular to a sample sealing tube for protecting air-sensitive samples, a preparation method and application thereof. Background technique [0002] Single crystal diffraction refers to the experimental method of determining the crystal structure of a single crystal using the diffraction effect of X-rays. At present, single crystal diffraction has become a powerful means to analyze molecular crystal structure. The single crystal diffraction experiment mainly includes four steps: 1) sample preparation; 2) single crystal sample loading; 3) diffraction test; 4) data analysis. Since the emergence of single crystal diffraction, the performance of instruments and the ability of analysis software have been improved. In the past, one structure was analyzed every year, and now one structure is analyzed in one hour. [0003] At present, the methods for loading single crystal samples mainl...
