Embodiment Construction

[0027] The technical solution of the present invention will be described in detail below in combination with specific embodiments and accompanying drawings, so as to make it more clear.

[0028] Such as figure 1 As shown, the embodiment of the present invention provides a sample sol method, which may include the following steps:

[0029] S10: placing the jig fixed with the sample to be sold in a dissolver, adding a dissolver into the dissolver and heating;

[0030] S20: Clamp the area of ​​the jig that is not covered with the sample to be sol, take out the jig from the dissolving agent, and observe whether the encapsulating colloid of the sample is completely dissolved;

[0031] S30: If the encapsulating colloid is not completely dissolved, place the fixture in the dissolving agent, and observe repeatedly until the encapsulating colloid of the sample is completely dissolved.

[0032] In this method, the sample is a sample whose surface is covered with encapsulating colloid. ...

Abstract

The invention relates to a method for dissolving the colloid of a sample, a tool and device for the same. The method comprises: placing a tool to which a sample with colloid to be dissolved is fixed in a dissolver, adding a dissolving agent to the dissolver and heating the dissolution agent; capturing an area, uncovered with the sample with colloid to be dissolved, on the tool, taking out the toolfrom the dissolving agent, and observing whether the encapsulation colloid of the sample is completely dissolved; if not, placing the tool in the dissolving agent and repeatedly observing the encapsulation colloid until the encapsulation colloid of the sample is completely dissolved. There is no need to contact the sample during the process of dissolving the colloid of the sample such that the damage rate is reduced in the process of dissolving the colloid of the sample.

Description

technical field [0001] The invention relates to the field of colloid technology, in particular to a sample sol method, fixtures and equipment for the sample sol method. Background technique [0002] In order to obtain the internal components of a sample whose surface layer is covered with encapsulating colloid, it is usually necessary to perform sol treatment on the sample, that is, to dissolve the encapsulating colloid. The traditional sample sol method is to use a chemical solution to corrode the encapsulation colloid of the sample, and observe repeatedly until the colloid is completely dissolved, so as to obtain the components inside the encapsulation colloid. [0003] For example, when performing sol-solution for LED (Light-Emitting Diode, lamp bead) to obtain lamp bead chips, it is necessary to first put the lamp bead sample into a chemical solution for dissolution, and then repeatedly clamp the sample for observation until the lamp bead encapsulation colloid Completel...
