  • Publication number: 20260002923
    Abstract: A testing device for measuring oil, gas and water contents in rock has a heating desorption unit that has a sample chamber for placing a rock sample to be detected, a crushing mechanism arranged within the sample chamber, and a heating mechanism. The heating desorption unit crushes and heats the rock sample in a sealed manner to achieve gas analysis and desorption analysis of oil and water contained therein, thus obtaining components to be detected. The device further has a cold trap collection unit in communication with the sample chamber, a light hydrocarbon capture unit in communication with the cold trap collection unit, a gas measuring unit in communication with the light hydrocarbon capture unit for measuring and calculating a gas volume; and a central control unit for controlling the testing device.

  • Patent number: 9207165
    Abstract: 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.
