    摘要: The present disclosure provides a frozen sample holder having an identification ring, and relates to the technical field of freezing sectioning-related equipment, the frozen sample holder having an identification ring comprising an identification ring structure and a frozen sample holder structure, wherein the identification ring structure is in connection with an outer wall of the frozen sample holder structure; and the identification ring structure includes an identification segment, which is configured to mark the information of a sample in the frozen sample holder structure. The present disclosure solves the technical problem existing in the operating process of freezing sectioning all along that multiple samples would easily be confused with each other due to the difficulty to mark frozen sample holders.

    摘要: A method includes introducing a fluidic sample into the void volume and onto the surface of a porous material, bringing the porous material into contact with a hydrophilic substrate compatible with a cryogenic Transmission Electron Microscope, separating the porous material from the substrate, and transferring a portion of the sample from the porous material to the substrate between their contact and separation.

    摘要: A particle concentration measurement system includes a first window and a second window in a housing. The first window and the second window respectively define a first end and a second end of an interaction region between the first window and the second window. The system also includes a particle-laden gas inlet through a wall of the housing between the first window and the second window. The particle-laden gas inlet introduces particle-laden gas from an environment that includes particles mixed with other materials into the interaction region. A first set of clean gas inlets through the wall of the housing are at different radial positions of the housing and at a first axial location of the housing, and a second set of clean gas inlets through the wall of the housing are at different radial positions of the housing and at a second axial location of the housing.
