New scanning electron microscope for nanomaterials

Thermo Fisher Scientific has developed a new Scanning Electron Microscope (SEM) which makes it possible for scientists to use a tabletop microscope to characterize the size, shape and chemical composition of nanoparticles at high resolution.

The Phenom Pharos G2 Desktop Field Emission Gun SEM makes it easier to resolve the morphology of nanomaterials in materials such as metals, minerals and ceramics at 2.0 nanometer (nm) resolution at 20 kilovolts (kV), the company said, compared to 2.5 nm in previous versions.

Researchers can also image soft, beam-sensitive or insulating samples at energy levels down to 1 kV, obtaining higher resolution views into polymers and multilayer organic films without damaging or obscuring their nanoscale features. Images can be obtained in just 30 seconds for high sample throughput, Thermo Fisher said.

‘The Phenom Pharos G2 progresses nanomaterial research by delivering high resolutions and a wide acceleration voltage range, all in a desktop system that can fit within a lab or office,’ said Rosy Lee, vice president of materials science at Thermo Fisher. ‘From more advanced textiles and food packaging to improved solar and wind energy, this easy-to-use instrument supports rapid innovation for a wide range of industries.’
