How Elemental Analysis Supports Compliance in Cobalt Production
Cobalt is a cornerstone of modern technology, powering electric vehicle batteries, renewable energy systems, and consumer electronics. Yet, its production carries significant ethical, environmental, and regulatory challenges. Compliance is not just a legal necessity but a moral obligation to address these concerns. Elemental analysis, particularly through X-ray Fluorescence (XRF), is a critical tool in meeting compliance standards. By providing precise, actionable insights into material composition and traceability, elemental analysis supports a transparent and sustainable cobalt supply chain.

Reducing the Particle Size Effect in XRF Measurements
Undertaking X-ray fluorescence (XRF) is an excellent way of ascertaining a material’s elemental make-up. Not only is XRF a non-destructive technique, meaning that the analyzed sample remains undamaged, but it can identify a variety of elements, starting with sodium (Na) and ending with uranium (U). Its ability to decipher the elements within a sample works through the application of X-rays. These X-rays can excite a material’s atoms, generating characteristic X-rays that have a specific energy that relates to an element, which can be deciphered through a detector. Unfortunately, there is something that can affect the accuracy of XRF measurements: the particle size effect.

Minimizing Matrix Effects in XRF Spectrometry
X-ray fluorescence (XRF) spectrometry is a mainstay in chemical analysis. It provides non-destructive elemental detection of major and trace elements—ranging from 100% to the sub-PPM range. This applies to a huge range of elements, typically from beryllium (Be) up to uranium (U). But it’s not without limitations. Matrix effects, for instance, pose a serious obstacle to accuracy. Elemental variations within the sample trigger these effects. They can disrupt X-ray absorption and fluorescence emission, which impairs results.
Fortunately, there are tried-and-trusted solutions to overcoming matrix effects.
1. Prioritize Proper Sample Preparation
The foundation of accurate XRF analysis begins with meticulous sample preparation. A homogenous and repre
