The holder has a beta-tilt of about +/-30°. The specimen cradle and clamping material (hexring and anti-twist washer) are made of beryllium to minimize unwanted X-ray signal from the holder. The holder has a Faraday-cup at the tip for possible measurement of the beam current (with an external picoampermeter). | |||

Classical furnace heating holder which is suited for standard 3mm samples. The heating furnace is made from tantalum and ONLY suited for heating in non-oxidizing gas environments (ETEM) up to about 1000°C. This holder is not suited for EDS because of the furnace design. | Classical furnace heating holder which is suited for standard 3mm samples.

The MEMS-based closed-cell holder offers the possibility of gas environments up to atmospheric pressure (1bar). Up to three gasses can be used simultaneously. Additionally, it offers temperature control up to 1000°C. The setup is also equipped with an residual gas analyzer to detect reaction products. | |||
