How do Electric Fusion Machines Actually Work?

Electric fusion machines are high-technology sample preparation systems used to create homogenous discs or beads from raw mineralogical materials – not to be confused with electrofusion devices, also known as butt welders.

The reason the verbiage here sounds so similar is that both methods of electric fusion rely on similar principles to complete different objectives. Electrofusion welding involves the heating, or in some cases pressurization, of two contacting workpieces until they form a joint. This is typically carried out via electronic resistance heating as opposed to open flame or plasma torch welding. Analytical scientists rely on remarkably similar principles when preparing a mineral or metallic sample for X-ray fluorescence (XRF) spectroscopy – provided they are usin...

Platinum Products for Electrochemical Analysis

Electrochemical analysis is a complex field of study concerning chemical reactions under electrical stimulation. This involves the transfer of electrons through the heterogeneous interface between an electrode and an ionic conductor. By analyzing the gain/loss of electrons from the ionic solution, it is possible to draw detailed conclusions about its chemical status, ionic concentration, kinetic behavior, mechanism of reaction, and more.

Accurately characterizing ionic solutions via electrochemical analysis requires a series of electrodes working in tandem. At XRF Scientific, we have years of experience manufacturing anodes and electrodes for complex analytical applications. Our suite of platinum products includes a choice of electrodes suitable for various forms of electrochemic...

X-ray Fluorescence: The Basics

Analytical chemistry is built on the premise of acquiring information about the composition and structure of sample materials through rigorous testing. This may involve the application of mechanical loads or extremely high temperatures to monitor the way that matter reacts to specific stressors. Although, the method applied fundamentally depends upon the properties of interest. Assessing the chemical content and structure of materials, for instance, is typically carried out via spectroscopic methods like X-ray fluorescence (XRF).

What is Spectroscopy?

Spectroscopy refers to a diverse toolset used to analyze materials based on various emission spectra. In this context, emission spectra are defined as the signals emitted by molecules after they have interact...
