EDX-8100 Energy Dispersive X-ray Fluorescence Spectrometer

Naturally occurring minerals in the Earth’s crust contain unique chemical signatures, which can reveal detailed information about the history of their formation and geographic origins.

In this free eBook, discover a suite of analytical technologies designed to assess the properties and composition of various minerals to help researchers understand how their instruments can be used for the analysis of gemstones for the jewelry industry, as well as basic research into the mineralogy of both volcanic and metamorphic rocks.

This eBook will also cover:

• Spectrophotometric analysis of gemstones
• X-ray analysis of precious stones
• Elemental mapping
• Electron probing of minerals in volcanic rocks

The U.S. Food and Drug Administration (FDA) identifies chemical hazards as serious threats to the food supply. Heavy metal contamination is among the many chemical hazards included in the official FDA guidance documents. Chemical contamination can be introduced at any stage in food production and processing. Heavy metals (e.g., cadmium, arsenic and mercury) can contaminate foods through agricultural practices or the use of contaminated soil or water. Additionally, heavy metals from equipment, containers or utensils can leach into food during processing and production.

Demands regarding the analysis of contaminants that are mixed in or adhered to products are increasing for food and chemical manufacturers and inspection agencies which are consigned inspections.

New guidelines governing the analysis of elemental impurities in pharmaceuticals are being implemented. Toxic heavy metals and residual metal catalysts may exist in the raw materials of Active Pharmaceutical Ingredients (APIs) or be added during the manufacturing process. These impurities may be a risk to human health.

EDX instruments have become capable in recent years of analysis accuracy comparable to that of low-output wavelength dispersive type instruments. Not only do they offer such conveniences as the ability to analyze powders as they are, their range of applicability has greatly widened to include the analysis of such substances as cement. This application note describes the analysis of pressure-formed cement standard powder samples using the new model EDX-8000.

In recent years, elemental analysis by EDX has been increasing due to the heightened concern for the environment. Even waste oil can quickly and easily be analyzed by EDX by merely pouring it as is into a container. This application note evaluates the repeatability and limit of detection in analysis using new, unused commercially available general oil that is similar waste oil using the EDX-7000.

This application note presents an example of quantitative analysis of a small amount of hijiki (a type of seaweed) using the background fundamental parameter Method (BG-FP) method.

Forensic spectroscopy encompasses a suite of analytical techniques designed to identify unknown substances and quantify trace elements with extreme precision and speed. In this SelectScience interview, Dr. Tom Spudich, Professor of Analytical Chemistry, explores how advanced tools like UV-Vis spectroscopy, GC-MS, FTIR with ATR, and ICP-OES are transforming forensic science workflows.

Discover how these methods are instrumental in diverse applications, from preserving historic documents through elemental analysis to detecting beverage adulterants like 1,4-butanediol. Learn how Shimadzu’s high-sensitivity instrumentation is slashing analysis times from hours to just 15 minutes, significantly boosting sample throughput and accessibility in the field.
