EM Sample Preparation Coating, Etching and Fracturing

Sample Preparation for EM: A Practical Guide to Coating and Freeze-Fracturing

From coatings done in a low-vacuum sputter coating machine at room-temperature to those done in high-vacuum and even at cryogenic temperatures, Leica coating solutions cover a large range of needs.…

Brief Introduction to Coating Technology for Electron Microscopy

Coating of samples is required in the field of electron microscopy to enable or improve the imaging of samples. Creating a conductive layer of metal on the sample inhibits charging, reduces thermal…

Carbon Thickness Evaluation in Electron Microscopy

The coating layers applied and used for electron microscopy imaging are commonly controlled and measured by quartz crystals. These crystals oscillate with a certain frequency (around 6 megahertz when…
