JEM-ARM300F: The Ultimate Atomic Resolution Transmission Electron Microscope

Transmission electron microscopy (TEM) has long been a tool essential for micro structure evaluation in the field of materials development.
However, as the fine structures of advanced materials are being designed at the nano level or atomic level, the synthetic process for such materials increasingly requires imaging and analysis at higher resolution.

To meet this demand, JEOL has focused on development of a transmission electron microscope incorporating spherical aberration correctors to exceed the current resolution boundary.
In 2009, JEOL announced the JEM-ARM200F, a 200 kV atomic resolution analytical transmission electron microscope featuring spherical aberration correctors, which achieved a resolution of 80 pm (scanning transmission (STEM) image) as the first ever commercial electron microscope.  To achieve the atomic level resolution, the JEM-ARM200F incorporates various capabilities to ensure highly stable operation.  With over 100 units of the ARM200F currently in operation worldwide, many researchers have become familiar with atomic level imaging and analysis.

Meanwhile, as aberration correctors are widely used, various new requirements for transmission electron microscopy are emerging, in addition to higher resolution, including higher analytical sensitivity, in-situ imaging, flexible accelerating voltage control, and ease of operation for aberration correction.

Thus, JEOL developed the JEM-ARM300F, a 300 kV atomic resolution transmission electron microscope featuring JEOL's own aberration correctors as an enhanced model of the JEM-ARM200F.
Nicknamed GRAND ARM, the JEM-ARM300F, incorporates JEOL's propriety dodecapole correctors, successfully increasing the resolution level to 63 pm (STEM resolution).
The GRAND ARM can be configured for ultra high resolution imaging or analytical applications for high sensitivity and in-situ analysis according to the user's needs.

The system is primarily intended for public and private research institutes and semiconductor manufacturers.

JEOL Reinvents Time-of-Flight Mass Spectrometry with Innovative SpiralTOF™ MALDI-TOF System

JEOL announced the introduction of the company’s first commercially available MALDI-TOF mass spectrometer, the JEOL JMS-S3000 SpiralTOF™. The SpiralTOF reinvents Time-of-Flight ion optics with an extended flight length in a compact footprint, delivering a resolving power of greater than 60,000 (FWHM) over a wide mass range of m/z 10-30,000 - the highest resolving power of all commercial MALDI-TOF systems.

JEOL’s patented technology consists of a staggered figure-8 ion trajectory of 17 meters. By refocusing the ion packets during each turn, the divergence of the ions is reduced over the flight distance. The SpiralTOF ion optical system is engineered to overcome the limits of delayed extraction with kinetic energy convergence resulting in high sensitivity, resolving power and mass accuracy (less than 1ppm) over a wide mass range.

To meet the diverse needs of researchers, the SpiralTOF is available in four configurations:

• MALDI-TOFMS with unsurpassed high mass resolving power and high mass accuracy

Additionally, a family of 300 to 930MHz NMR spectrometers completes its chemical analysis product line.

First JEOL JEM-ARM200F Electron Microscope Produces Atomic Resolution Data in Record Time at University of San Antonio

The first transmission electron microscope of its caliber to be installed, the eagerly awaited atomic resolution JEOL JEM-ARM200F TEM arrived at the University of Texas at San Antonio in January, and by early February began producing outstanding imaging results.
“Achieving raw HAADF images showing at least 78 picometer information transfer in just three weeks demonstrates the stability of this all-new instrument and the skill of the UTSA-JEOL team to quickly power up the first TEM of its kind,” said Dr. Thomas Isabell, JEOL USA Director of the TEM Product Division.

UTSA physics and astronomy department chair Dr. Miguel Yacaman, a renowned electron microscopist and nanotechnology researcher, tested the new ARM200F performance on Si <110> samples as the JEOL engineering, service and applications team worked closely together to install the TEM in UTSA’s Advanced Microscopy Lab.

“At the level of this new microscope, the potential for new discoveries is enormous,” says Yacaman, who likened the capabilities of the JEOL ARM200F for sub-atomic research to those of the Hubble telescope for intergalactic exploration.

The ARM200F represents more than 60 years of TEM expertise at JEOL and was designed from the ground up to integrate aberration correction into a super-shielded electron column that safeguards the ultrahigh-powered optics from environmental interferences.

“This first installation of the ARM200F demonstrates that JEOL is out in front in the development of stable, ultra-quality instruments and showcases just what our service and applications teams are capable of.” said Isabell.

The JEM-ARM200F enables both atom-by-atom imaging resolution and unmatched spatial resolution for atom-to-atom chemical mapping of materials, including EDS (energy-dispersive x-ray spectroscopy) and EELS (electron energy-loss spectroscopy). The completely new electron column design integrates S/TEM with Cs correction for atomic spatial energy resolution combined with high probe currents for microanalysis.
