ElectroChemistry
Hummingbird Scientific was the first company to provide a commercial holder facilitating liquid-electrochemical experiments inside the TEM. In the years following its original release, we have continued to refine the holder's capabilities. The holder enables electrochemical research via integrated biasing contacts that connect to our specially-patterned electrochemical chips, which available in a variety of materials. Among other topics, the system has been used for key research into battery materials.
Heating
Our heating system is optimized for moderate temperature requirements. Heating is performed using a thin-film heater inside the liquid cell, which heats up to the boiling point of your solution (max 200?C).
Spectroscopy
Hummingbird Scientific’s liquid TEM holder includes an energy-dispersive X-ray spectroscopy (EDS) option for spectroscopic measurement. Our specialized chips ensure the thinnest possible liquid layer, allowing for electron energy loss spectroscopy (EELS) inside the liquid cell. This in turn allows researchers to perform direct elemental analysis and mapping at high magnifications. The EDS liquid-cell holder's large viewing angle allows direct access from the sample to the EDS detector.
Vapor System
Hummingbird Scientific’s low-pressure vapor system allows researchers to introduce water vapor into the sample chamber of our fluid TEM sample holders, thus providing greater control over in-situ reaction conditions and protecting delicate biological samples. The system is available as an add-on to Hummingbird’s liquid and gas holders and can be used with all existing environmental cell systems.
TEM Safety
Our high vacuum pumping station is a compact all-in-one vacuum storage and seal checking solution for TEM specimen holders. The station features short pumping and venting times, a low base pressure (10-6mbar), and a glass viewing port for the holder tip.
