JEOL’s Particle Analysis Software 3 (PA3) enhances the capability of your analytical SEM by automating the detection, EDS analysis and classification of particles, grains or other features in your samples. Fully integrated with our SEM-EDS systems, PA3 increases throughput and productivity by providing fast, unattended measurements across large areas of a sample, or multiple samples.

Phase Analysis provides a new level of automation to your JEOL EDS data analysis and interpretation workflows

This Polymer note introduces a broad range of instruments used for polymer analysis and their applications.

The Pulse system is a modular and retrofittable upgrade to improve the speed and precision of scanning transmission electron microscopy signals.

When a sample is exposed to the electron beam in a scanning electron microscope a variety of signals are generated. X-rays being one of those signals that can provide valuable insight into a materials chemical makeup. The collected X-ray signal includes background X-ray radiation and more importantly, X-rays of specific energies, that are characteristic of the elements present in the sample. For this reason, an energy dispersive X-ray detector (EDS) is one of the most common detectors that is added to a scanning electron microscope (SEM). It is used to not only determine the elements present in a sample but in many instances can give insight to the quantity as well as the spatial distribution of these elements over very small volumes.

The IDES Relativity Electrostatic Subframing System multiplies the frame rate of cameras on JEOL TEMs. Microscopes equipped with Relativity achieve exceptional time resolution, data throughput, and advanced automation capabilities. Addition of Relativity allows current JEOL TEM users to forego expensive camera upgrades to their existing systems, instead relying on installation of an electrostatic optics assembly in a wide-angle camera port. These optics rapidly deflect the image data to different regions (subframes) of the camera in a programmable sequence. Each camera readout contains a tiled array of crisp, blur-free subframes. Raw data is automatically analyzed to give a stack of open format images that are loaded back into the camera control software for viewing or further analysis.

The first commercially available SEM was introduced over 50 years ago and to this day there is still no internationally accepted standard for determining SEM resolution. To add to the confusion, each SEM manufacturer relies on their own sample and methods for determining resolution.

Defining the edge of a particle manually is also always subjective in nature; values will differ from one person to the next based on how that person interprets or ‘sees’ the edge of a particle.
