Apreo ChemiSEM System: Smarter imaging and direct electron detection EBSD for material characterization
10:00 a.m. to 10:30 a.m.
Presented by Chris Stephens
In this session, we will present the latest advancements in material characterization using the Thermo Scientific Apreo ChemiSEM System, focusing on its Trinity detection system, direct electron detection for EBSD, and real-time elemental analysis with integrated EDS. The Trinity detection system, with three in lens detectors leveraging advanced column design, provides multiple imaging modalities for optimal contrast and resolution across a wide range of material types, including amorphous, non-conductive, and porous structures. The talk will also explore dedicated Smart Imaging strategies and automated real-time image optimization techniques. Additionally, we will discuss the integration of automated analytical workflows for materials science applications, including real-time EDS elemental mapping. Finally, we will introduce TruePix-based electron counting, which enables systematic diffraction pattern analysis by detecting every electron above a threshold. We’ll highlight low-kV direct electron detection EBSD, demonstrating its benefits for beam-sensitive materials and high-resolution crystallographic analysis. We will also define the median electron count (MEC) metric in EBSP, examining its applications in both SEM imaging and the characterization of 2D material layer thicknesses.
