Abstract
The invention belongs to physical experiment instruments, and particularly relates to a split-type physical absorption instrument sample pipe. The split-type physical absorption instrument sample pipe is characterized by being divided into an upper part and a lower part, wherein sand plates or sand cores are accommodated in an upper portion pipe body, the lower end of a lower portion pipe body is closed, and the upper end of the lower portion pipe body is connected with the lower end of the upper portion pipe body in a sealing mode. The lower end of the upper portion pipe body can be a polished opening, the upper end of the lower portion pipe body can be a polished opening, and the lower end of the upper portion pipe body or the upper end of the lower portion pipe body can be cone-shaped bodies or cylindrical bodies. The split-type physical absorption instrument sample pipe can prevent powder or tiny particle samples from being pumped into a system, is simple in structure, is more practical and more convenient to use because of split-type combination on the basis that the basic structure of a prior physical absorption instrument sample pipe is not changed.
Description
Technical field
The invention belongs to a kind of physical experiment apparatus, particularly relate to a kind of split type physical adsorption appearance sample cell.
Background technology
Can obtain the physical parameters such as specific area, pore size distribution, pore volume of material by the physical absorption performance of gases such as test nitrogen etc., at present, normally testing sample is packed in the physical adsorption appearance sample cell (Fig. 1), the sample cell that will contain testing sample then connects with physical adsorption appearance to be tested.In the sample test process, need carry out evacuation processes to remove the impurity of sample surfaces absorption to articles for use.Yet when testing sample is a powder or during than granule, sample is drawn in the system probably in the process of evacuation processes, and then pollutes and damage physical adsorption appearance.
Summary of the invention
At the problems referred to above, the invention provides a kind of split type physical adsorption appearance sample cell, be that a kind of powder or less particulate samples avoided is drawn into sample cell in the system.
Technical scheme of the present invention is as follows:
A kind of split type physical adsorption appearance sample cell, this sample cell are divided into two parts up and down, and the top body contains sand plate or core, the lower end closed of bottom body, and the lower end of the upper end of bottom body and top body is tightly connected.
Further feature, the lower end of top body is a ground, the upper end of bottom body is a ground.
Further feature, the upper end of the lower end of top body or bottom body is a cone, by cone upper and lower port is closely linked together, sealing effectiveness is better.
Further feature, a kind of split type physical adsorption appearance sample cell according to claim 1 is characterized in that the upper end of the lower end of top body and bottom body is a column, and is middle by the column sealed attachment.
The invention has the beneficial effects as follows simple in structurely, on basis on the basic structure that does not change original physical adsorption appearance sample cell, connect by split type, make the physical adsorption appearance sample cell more practical, make things convenient for.
