A method of sampling ingredients of an oil-bearing inclusion includes a) providing a first container and a second container, an external diameter of the first container being smaller than an internal diameter of the second container, and the first and second containers both being transparent; b) adding a solvent into the first container and sealing said first container; c) adding an oil-bearing inclusion sample into the second container, and putting the first container that contains the solvent and is sealed in step b) into the second container; and d) using a laser to ablate the oil-bearing inclusion sample contained in the second container that is sealed in step c), and using the laser to break an end portion of the first container close to the sample on condition that the second container is maintained complete, so as to allow the solvent in the first container to enter the second container.

Method of sampling oil-bearing inclusion

The present invention relates to a sample chamber for laser ablation analysis of fluid inclusions, comprising a sample cell having a sample cell through-hole extending along the vertical direction and a sample channel extending through the sample cell in a direction transverse to the vertical direction and communicating with the sample cell through-hole. A transparent element is arranged on each of the top and bottom sides of the sample cell through-hole, and is fixed to the sample cell through a fixing ring. The sample chamber further comprises a base comprising a viewing hole and a receiving portion for receiving the sample cell, wherein the viewing hole is coaxially aligned with the sample cell through-hole when the sample cell is placed within the receiving portion. According to the sample chamber of the present invention, it is only necessary to change the sample cell during replacement of the sample chamber, which leads to a convenient operation. At the same time, light from the microscope can pass through the viewing hole, so that the effect of observation is improved.
