Release of the JSM-7900 UHR FEG-SEM

JSM-7900F is JEOL’s new flagship FE-SEM which combines ultimate high resolution imaging, enhanced stability and exceptional ease of use for any level of operator in multi-user environment.

Newly developed functionality that integrates lens control system and automatic technology, "Neo Engine" (New Electron Optical Engine) is a standard feature, allowing for fast and easy image acquisition at any accelerating voltage and probe current.
The system is the premier example of the JEOL’s advanced electron optics technology.

Release of the JIB-4700F Multi Beam System

The JIB-4700F features a hybrid conical objective lens, GENTLEBEAM™ (GB) mode and an in-lens detector system to deliver a guaranteed resolution of 1.6nm at a low accelerating voltage of 1 kV. Using an "in-lens Schottky-emission electron gun" that produces an electron beam with a maximum probe-current of 300nA, this newly-developed instrument allows for high-resolution observations and fast analyses. For the FIB column, a high-current density Ga ion beam of up to 90nA maximum probe-current is employed for fast ion milling and processing of specimens.

Concurrent with high-speed cross-section processing by FIB, high-resolution SEM observations and fast analyses can be conducted utilizing energy dispersive X-ray spectroscopy (EDS) and electron backscatter diffraction (EBSD). Additionally, a three-dimensional analysis function that automatically captures SEM images at certain intervals in cross-section processing is provided as one of the JIB-4700F's standard features.

JEOL introduces the InfiTOF Spectrometer JMS-MT3010HRGA

The InfiTOF  Spectrometer JMS-MT3010HRGA is a Time-of-Flight Mass Spectrometer using Multi-turn® and Perfect focusing® technologies, which achieves high mass-resolving power in a very compact package. This mass spectrometer is designed for real time monitoring of directly introduced gas. It is a high mass-resolution mass spectrometer with stability for real time gas monitoring and capable of elemental composition determination through accurate mass measurement.

High-Resolution Gas Monitoring

MS measurement results shown below are acquired by introducing the standard gases (10 ppm each) and then performing sequential measurement of 4 hours at high mass resolution conditions. High-resolution gas monitoring is enabled for all components over a long period of time with high stability.

High Mass Resolving Power

An innovative Multi-Turn technology makes the spectrometer compact while maintaining high mass resolving power. The maximum resolving power of 40,000 (FWHM) or higher is achieved even for a low-mass range, such as nitrogen molecule (28.0062 Da). With the conventional compact spectrometers, it was difficult to perform mass separation of gas components like carbon monoxide (27.9949) and nitrogen molecule (28.0062), or carbon dioxide (43.9898) and nitrous oxide (44.0011 Da). However, a new InfiTOF can easily separate these gas components and moreover, this revolutionized spectrometer calculates elemental composition through accurate mass measurement. 

Capable of Measuring Hydrogen Ions

JMS-MT3010HRGA is capable of measuring proton (1.0078 Da; a fragment ion of hydrogen molecule) as well as hydrogen molecule (2.0157 Da). Hydrogen is very difficult to measure with a time-of-flight mass spectrometer because of very low mass and fast flight velocity compared to other elements. The JMS-MT3010HRGA, however, achieves stable measurement of these species. This capability will contribute to research of various advanced materials, including electrolytic reactions and catalyst reactions.
