Energy Dispersive Spectroscopy

Energy dispersive spectroscopy (EDS) collects detailed elemental information along with electron microscopy images, providing critical compositional context for EM observations. With EDS, chemical composition can be determined from quick, holistic surface scans down to individual atoms.

3D EDS Tomography

Modern materials research is increasingly reliant on nanoscale analysis in three dimensions. 3D characterization, including compositional data for full chemical and structural context, is possible with 3D EM and energy dispersive X-ray spectroscopy.

EDS Elemental Analysis

Thermo Scientific Phenom Elemental Mapping Software provides fast and reliable information on the distribution of chemical elements within a sample.

Atomic-Scale EDS

Atomic-resolution EDS provides unparalleled chemical context for materials analysis by differentiating the elemental identity of individual atoms. When combined with high-resolution TEM, it is possible to observe the precise organization of atoms in a sample.

Electron Energy Loss Spectroscopy (EELS)

Materials science research benefits from high-resolution EELS for a wide range of analytical applications. This includes high-throughput, high signal-to-noise-ratio elemental mapping, as well as probing of oxidation states and surface phonons.

In Situ experimentation

Direct, real-time observation of microstructural changes with electron microscopy is necessary to understand the underlying principles of dynamic processes such as recrystallization, grain growth, and phase transformation during heating, cooling, and wetting.

Particle analysis

Particle analysis plays a vital role in nanomaterials research and quality control. The nanometer-scale resolution and superior imaging of electron microscopy can be combined with specialized software for rapid characterization of powders and particles.

Multi-scale analysis

Novel materials must be analyzed at ever higher resolution while retaining the larger context of the sample. Multi-scale analysis allows for the correlation of various imaging tools and modalities such as X-ray microCT, DualBeam, Laser PFIB, SEM and TEM.

Automated Particle Workflow

The Automated NanoParticle Workflow (APW) is a transmission electron microscope workflow for nanoparticle analysis, offering large area, high resolution imaging and data acquisition at the nanoscale, with on-the-fly processing.
