Abstract
An environmental chamber for a transmission electron microscope, in which a specimen is held in position within the transmission electron microscope so an electron beam passes through the specimen to a detector. A removable sleeve surrounds the specimen holder and is sealed at both ends by a seal between the removable sleeve and the specimen holder to form a differential pressure chamber. Apertures are formed in the removable sleeve allowing the electron beam to pass through the specimen to the detector. A vacuum line allows gases to be removed from the differential chamber. A reactive inlet line extends into the differential chamber to allow a material to be introduced onto the specimen.
