Hummingbird Scientific’s liquid TEM holder includes an energy-dispersive X-ray spectroscopy (EDS) feature for spectroscopic measurement inside the liquid cell. 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 ensures direct access from the sample to the EDS detector (even for multiple-detector configurations).
