 Pre-register for this Webinar
Energy-filtered transmission electron microscopy (EFTEM) can reveal the elemental composition of natural and man-made structures at the micro-, nano-, and even sub-nanometer scale. This webinar is designed for microscope operators wishing to understand and perform EFTEM acquisition within DigitalMicrograph. We will introduce EFTEM imaging and discuss the basic theory and instrumentation behind this valuable acquisition mode. We will then discuss the operation and data analysis of specific EFTEM modes, including:
· Zero-loss filtering
· Contrast tuning
· Jump Ratio Imaging
· Elemental Mapping
· Chemical State Mapping During the Webinar, we will discuss ways to optimize the data acquisition and point out how to recognize and avoid possible artifacts. Familiarity with TEM microscope operation and DigitalMicrograph are suggested but not required. There will be a short question and answer period following the webinar.
About the Presenter:
This webinar will be presented by Dr. Ray Twesten of Gatan, Inc. Ray has over 15 years experience in electron microscopy. Before joining Gatan, Ray had over 7 years experience overseeing the (S)TEM operations at the University of Illinois’ Center for Microanalysis of Materials, where he was exposed to a broad range of materials problems requiring EELS and EFTEM for their solution.
