A system and method for imaging a biological sample using a freezable fluid cell system is disclosed. The freezable fluid cell comprises a top chip, a bottom chip, and a spacer to control the thickness of a vitrified biological sample. The spacer is positioned between the top chip and the bottom chip to define a channel that is in fluid communication with an inlet port and an exit port to the freezable fluid cell system. The channel can be filled with a biological sample, vitrified, and imaged to produce high-resolution electron microscopic image.

An object of the invention is to easily acquire images of a position corresponding among a plurality of sample sections in an imaging device that acquires images of the plurality of sample sections. The imaging device according to the invention generates a cursor for specifying a first observation region and a contour portion of a first sample section, and superimposes the cursor on a contour portion of a second sample section so as to calculate coordinates of a second observation region of the second sample section.

A sample holder for holding a sample comprising a drill core sample or drill cuttings during X-ray transmission measurements and fluorescence measurements is disclosed. The sample holder comprises a confining structure having an axial direction and being adapted to, during measurement, at least partially enclose the sample and to restrict movement of the sample in a direction intersecting the axial direction. The confining structure comprises at least one region facing away from the axial direction and allowing exciting radiation impinging on, and fluorescent radiation emanating from, the sample during measurement to pass therethrough. An apparatus adapted for receiving such a sample holder is also disclosed, comprising a ray source, an X-ray transmission detector, a fluorescence detector and rotating means for rotating at least one of the sample holder, the X-ray source, the X-ray transmission detector and the fluorescence detector. Further, a system comprising such a sample holder and apparatus is disclosed.
