AA or ICP-OES/MS is often viewed as the golden standard to analyze elements during the pharmaceutical manufacturing process, from drug discovery to the QA/QC of final formulations.
While extremely accurate, these techniques have the downside of requiring the sample to be in liquid form when analyzing, resulting in a very arduous sample-preparation process and long analysis time.
In this seminar, we would introduce Energy-Dispersive X-Ray Fluoroscopy (EDX) as an alternative technique to perform elemental analysis that requires little sample preparation, is easy to use and can provide results quickly; and how it could be used in various areas of the pharmaceutical industry.
Learning Objectives:
<ul>
<li>Understanding how EDX can be used to perform elemental analysis
</li>
<li>Understanding how EDX can be used in the Pharma Industry
</li>
<li>Advantages of using EDX for elemental analysis
</li>

EDX: A Fast & Simple Technique

Traditionally, photometric methods are used to determine the concentration of a specific metal in a process stream. However, metal interferences in photometric methods pose significant challenges, leading to inaccurate readings of target analytes. Online X-ray fluorescence (XRF) is a powerful and efficient technique that offers a solution to these challenges and can be used to monitor multiple analytes simultaneously.
