Thermo Fisher Scientific has new electron microscopy and microanalysis solutions

Baltimore, MD-based Thermo Fisher Scientific recently displayed additions and advances to its portfolio of electron microscopy and microanalysis solutions aimed at academic and industrial customers who are working on today’s most difficult materials science and life sciences problems. The innovations were being presented at the Microscopy and Microanalysis 2018 Meeting at the Baltimore Convention Center.

Amongst the new products on offer were:

• The Phenom Pharos microscope, the first desktop scanning electron microscope (SEM) to include a field emission gun (FEG). Easy operation and advanced hardware design enable fast time-to-image and easy handling. With this new instrument, Thermo Fisher now offers academic and industrial customers a complete portfolio of SEMs ranging from desktop instruments to high-end floor models.

• The Lumis electron backscatter diffraction (EBSD) detector is used in SEM to study crystalline and polycrystalline materials. It allows material scientists, metallurgists and geoscientists to understand the structure, crystal orientation and phase of SEM samples and monitor structural transformations in samples. It combines advanced optics with a new complementary metaloxide semiconductor (CMOS) sensor that collects more than 2.2 megapixels which, the company says, is the largest number of pixels of any EBSD detector on the market. The detector is integrated with the Pathfinder 2.0 microanalysis software to complement EDS or WDS analysis.

• The newest Thermo Scientific Themis Z scanning transmission electron microscope (STEM) builds on its sub-Angstrom STEM imaging capability with the S-CORR probe aberration correction. With S-CORR, the Themis Z is designed to deliver unsurpassed STEM imaging and spectroscopy performance at low accelerating voltages, allowing scientists to analyze materials such as batteries, fuel cells, catalysts and lightweight metals and alloys that have historically been difficult to image. By improving the probe size and shape, while preserving sample integrity during investigation, researchers can better understand how to improve the performance of materials by revealing their structure and chemistry at the atomic level.

As well, Thermo Fisher has upgraded its portfolio of instruments, workflows and applications including:

STEM Maps and EDS Maps software which now include performance increases and connection to energy- dispersive X-ray spectroscopy (EDS), allowing users to complement high resolution imaging performance and elemental information from large areas across multiple imaging platforms;

• an updated HeliScan microCT analyzer design provides improved resolutions down to 400 nm;

Cryo-Ele Microscopy Single Particle Analysis (cryo-EM SPA) with increased automation, simplified alignments and optical enhancements for cryo-TEMs;

Cryo-EM Tomography a new integrated cryo-tomography workflow which seamlessly integrates light microscopes from Leica with cryo-EMs from Thermo Fisher;

DualBeam focused ion beam scanning electron microscopes (FIBSEMs) upgrades offering state-of-theart automation software to enable the highest-quality sample preparation for users of all experience levels in the shortest amount of time; advanced 3D materials characterization; a Pythonbased scripting engine to automate experiments; plasma FIB-SEM DualBeams to broaden the length scale and increase throughput; a multiple species source to broaden the applications space.
