ELECTRON MICROSCOPE AND ELECTRON MICROSCOPE SAMPLE RETAINING DEVICE

摘要

An objective of the present invention is to provide an electron microscope and an electron microscope sample retaining device whereby it is possible to easily and safely produce either a gas or liquid environment within an electron microscope, and to observe a sample therewithin and a reaction thereof at high resolution. An electron microscope comprises a sample retaining means (6) for retaining a sample (23). The sample (23) is positioned within a capillary (17) wherethrough it is possible for an electron beam to pass. The electron microscope further comprises: a supply device wherein which supplies either a gas or a liquid within the capillary (17); and a recovery device which recovers the gas or liquid. The electron microscope acquires a sample image of the sample while streaming the gas or liquid.
