JXA-8230 Electron Probe Microanalyser
JEOL has developed a new EPMA(Electron Probe Microanalyser), that continues a long history of EPMA development extending over nearly a half century. The JXA-8230, designed for user-friendly operations, provides for a complete range of analyses through a new, simple to use, PC-based interface. The high-accuracy and fast speeds offered by the JXA-8230 are a result of its sophisticated hardware developed from JEOL's EPMA technologies refined over nearly 50 years. The JXA-8230 is powerful, next-generation, analytical tool that fully meets all of the requirements of an EPMA.
The EDS, which is a versatile and easy-to-use X ray detector, can be mounted. A combined WDS snd EDS system provides a seamless and user-friendly environment for analysis.
JEOL commercialized the world's first FE-EPMA, the JXA-8500F in 2003. This highly regarded FE-EPMA has long been used in various fields, such as: metals, materials and geology in both industry and academia. The JXA-8530FPlus is a third-generation FE-EPMA that comes with enhanced analytical and imaging capabilities. The In-Lens Schottky field emission electron gun combined with new software provides higher throughput while maintaining high stability, thus allowing a wider range of EPMA applications to be achieved with higher resolution.
The In-Lens Schottky Plus FEG EPMA version, with an optimized angular current density, allows for analysis with a large probe current of 2μA or more. The resolution of secondary electron image has been improved even under analytical conditions by automatically adjusting for the correct convergence angle.
A wealth of Microsoft Windows®-based advanced applications systems are available, including:
- Trace Element Analysis Program for simpler, optimized analysis of trace elements including adding data collected from up to 5 spectrometers,
- Phase Map Maker for automatic creation of phase maps based on principal components,
- Non-Flat Surface Analysis Program for automated WDS analysis of specimens with surface irregularities. This is possible due to the large Z travel of the stage (7.5 mm).
Various X-ray spectrometers (WDSs) can be selected: a Rowland circle radius of 140 mm (140R) or 100 mm (100R), 2 crystal or 4 crystal configurations and a mix of standard or large size crystals.
The XCE (2 xtl) X-ray Spectrometer, the FCS (4 xtl) X-ray spectrometer and the L (large 2 xtl) X-ray Spectrometer for 140R have wide spectrometry range and provide superior wavelength resolution and peak-to-background ratio. The H Type X-ray Spectrometer of 100R provides high X-ray intensity. Users can select from these spectrometers depending on requirements.
The JXA-8530FPlus comes with JEOL's 30mm2 silicon-drift detector (SDD).
A high count-rate SDD along with an in-situ variable aperture enables EDS analysis at WDS conditions. EDS spectra, maps and line scans can be acquired simultaneously with WDS data.
The JXA-8530FPlus is equipped with a highly-expandable specimen chamber and specimen exchange chamber, enabling you to integrate a variety of optional attachments on the chamber.
