April 30, 2021 -- Thermo Fisher Scientific has launched a new cold field emission gun (CFEG), the Thermo Scientific E-CFEG, being offered as a value-added component for the Thermo Scientific Krios cryo-transmission electron microscope (Cryo-TEM).
Together, as part of four major components, the E-CFEG enables improvement upon resolution levels for single particle analysis.
The E-CFEG has a narrow energy spread that results in high contrast images. It joins the Thermo Scientific Selectris and Selectris X imaging filters, which provide stability, ease of use, and performance.
It also accompanies the company's Falcon 4 camera direct electron detector, which generates images with high contrast and high signal-to-noise ratio as well as faster throughput than the previous generation. Company leaders say when integrated with the Thermo Scientific Krios Cryo-TEM, these systems help advance cryo-electron microscope discovery with high contrast, resolution, and speed.
