Apreo ChemiSEM

High-performance SEM with EDS and EBSD for sub-nanometer resolution analysis

The Thermo Scientific Apreo ChemiSEM System provides outstanding nanometer-scale resolution at an optimized 10 mm analytical working distance. Its versatile FEG source permits high-resolution characterization across challenging sample types, including nanomaterials, magnetics, composites, and beam-sensitive specimens.

Seamlessly combining imaging and compositional analysis, the platform features fully integrated EDS. This allows operators to run live, quantitative elemental mapping within a single, unified interface, bypass traditional system-switching, and accelerate data acquisition.

Operational efficiency is further enhanced by a suite of upgraded hardware features: self-aligning electron optics, multiple detector configurations, an easily accessible large stage with a multi-sample holder, and accelerated vacuum pump-down cycles to minimize sample-loading downtime.

Features

High performance, resolution, and contrast
The Apreo 2 combines advanced optics, detection systems, and automation to make high-resolution imaging accessible, even for users who are new to SEM.

Wide range of sample types
Designed for maximum versatility, the Apreo 2 enables high-quality, high-resolution imaging across a variety of sample types. Whether working with insulating, beam-sensitive, or magnetic materials, the Apreo 2’s unique optics, detection options, and beam control ensure easy imaging regardless of sample properties.

Live quantitative EDS with ChemiSEM
ChemiSEM provides live, quantitative elemental mapping, delivering elemental information in real time, ensuring fast and easy results.

Integrated EBSD EDS technology for complete materials analysis

Accessible Microstructural Analysis: The TruePix EBSD Detector and intuitive xTalView software demystify advanced characterization, offering step-by-step guidance from setup through to data processing.

Built for Busy Labs & Industry: Specifically designed for multi-user R&D facilities and production environments, prioritizing ease-of-use without sacrificing reliable, repeatable results.

Multi-Technique Integration: Merges chemical and structural data into a single, comprehensive package, helping your team accelerate materials development and tighten quality control.

Advanced automation
From optical alignment to image acquisition, the Apreo 2 incorporates a range of automated features to optimize imaging efficiency. FLASH Technology automates image fine-tuning, while the unique Undo function allows users to efficiently explore different imaging conditions. Thermo Scientific Maps software automates large-area acquisition with up to four simultaneous signals.

Performance at long working distances
The Apreo 2 is the only SEM that delivers 1-nanometer resolution and excellent image quality at a 10 mm analytical working distance. Users can simultaneously explore sample morphology, topography, and surface information while maintaining a safe distance from the pole piece. Its high-speed, high-sensitivity in-lens backscattered detector ensures BSE detection even at ultra-low beam currents, down to a few pA.
