TEM Optical Gas Heating Holder

Operando heating, biasing under environmental conditions

Enclosed Optical Gas Heating Cell Inside the TEM

The Hummingbird Scientific TEM Optical Gas Heating Sample Holder enables in-situ TEM imaging of gas-solid reactions influenced by optical illumination, heating, gas composition, pressure, and electrical bias. The enclosed microchip gas cell supports atmospheric and elevated-pressure gas experiments up to 2 bar while maintaining microscope vacuum protection and stable nanoscale imaging.

Light-Stimulated Gas-Phase Reaction Workflows

A fiber optic feedthrough delivers light to samples mounted on SiN viewing membranes, enabling studies of heterogeneous photocatalysis, high-temperature photochemical reactions, growth and dissolution dynamics, light-assisted corrosion, and photo-sensitive thin films.

‍

Engineered for Reproducible Setup

A precision-machined, screw-free chip loading mechanism provides self-aligning viewing windows and controlled compression for repeatable gas-cell assembly. Hummingbird gas delivery, heating, sample chips, and software support experiments that correlate structure, composition, temperature, gas chemistry, pressure, and optical stimulus in real time.
