A method of preparing a sample for study in a charged-particle microscope, comprising the following steps:
- Providing a substantially planar sample holder having opposed faces substantially parallel to one another, comprising at least one aperture that connects said faces and across which a membrane has been mounted, which membrane comprises at least one perforation;
- Spanning a film of aqueous liquid across said perforation, which liquid comprises at least one study specimen suspended therein,
particularly comprising the following steps:
- Prior to said spanning step, placing a blotting sheet of blotting material in intimate contact with a first surface of said membrane, at a side distal from said sample holder;
- Depositing said aqueous liquid through said aperture and onto a second surface of said membrane, opposite said first surface;
- Subsequently removing said blotting sheet from said membrane. |
