Analytical Instrument Documents

This Solid-state battery Note has been created to provide solutions and reference information for research and development of solid-state batteries evolving from the lithium ion batteries (LIBs).

Here, we combine ED and solid-state NMR through the first principle quantum computation with the NMR crystallography approach for crystalline structure solution. The method, electron and NMR nano-crystallography, can be applied to nano- to micro-crystals even for mixture samples.

The applications for lithium ion batteries (LIB) cover a wide range, from power sources for personal computers and mobile devices to automobiles, and there is always a demand for even better performance and safety. In order to ensure the performance and quality of LIB, analysis and evaluation using high-performance assessment systems is necessary. JEOL offers a full line-up of equipment to support the development of new LIB technologies and to improve product quality, including instruments for morphology observation and surface analysis, chemical analysis systems to perform structural analysis on a molecular level, as well as fabrication systems to create high-performance coatings and powders. This LIB note offers solutions for researchers and engineers who are looking for the best equipment for their application.

JEOL offers numerous analytical tools to support both "food safety & security" as well as various evaluations of primary, secondary and tertiary functions of foodstuffs which are useful for a wide range of users associated with this field. This Foodnote introduces the features of each of the instruments and actual analysis examples, and is designed for researchers and engineers who are considering purchases of instruments. This brochure also presents comprehensive evaluations and analysis solutions that can be achieved with combinations of multiple instruments.

This Bionote presents an overview of the basics, namely principles and features of various instruments, as well as application examples using numerous optional attachments. We hope that the Bionote will assist researchers and engineers who intend to perform analyses in finding and exploring new approaches.

Introduction: In recent years, polymer materials have become more complex due to increased composition and diversification so that a one-sided analysis is insufficient and multifaceted observations and analyses are required. In response to this need, JEOL has engaged in applied research under the keyword of "YOKOGUSHI" (multifaceted cross-instrumental) using various instruments organically. In this Urushi Note, multifaceted analysis methods for polymer materials are illustrated using the examples of natural lacquer (urushi) analysis.

In this report, we have expanded MALDI-MSI to analyzing a PET film that was exposed to UV radiation. Additionally, a SEM was used to look at the morphological differences in the PET film before and after UV irradiation.

Since 1949, the JEOL legacy has been one of outstanding innovation in developing instruments used to advance scientific research and technology. JEOL has over 60 years of expertise in the field of electron microscopy, more than 50 years in mass spectrometry. In this applications note, we performed an analysis of a Gold Star Mothers Postage Stamp by using three JEOL instruments. We used the JSM-IT300LV which the latest addition to JEOL‘s popular series of analytical low vacuum SEM, , the JMS-T100LP “AccuTOF- DART” the first commercially available ambient ionization mass spectrometer, and the JMS-S3000 “SpiralTOF” which has highest mass-resolution and mass accuracy of all commercially available MALDI-TOFMS systems. We can therefore correlate analyses from various analytical techniques on the same sample.

Smokeless powders are often used in improvised explosive devices. The formulations for smokeless powders vary between manufacturers and between brands from a given manufacturer; ingredients include energetics, stabilizers, plasticizers and deterrents. Both chemical composition and morphology are important in characterizing smokeless powders. Chemical analysis of smokeless powders can provide valuable forensic evidence. Observation with the SEM can reveal morphological information to help with identification. Here we show how SEM-EDS analysis can be used to identify inorganic components, and how the AccuTOF-DART mass spectrometer can rapidly identify the organic components and provide a chemical fingerprint that can be used to identify individual powder particles.

A batch of contaminated welding wire received from a vendor by a customer was causing problems in a manufacturing process. Visual comparison of the clean and contaminated wire did not show any obvious differences, but the contamination was readily observed on backscatter electron images obtained with the JEOL IT300 scanning electron microscope.
