Overcoming Challenges in XRF Light Element Analysis: The Role of Helium and Vacuum Analyzing light elements, ranging from Sodium (Na, atomic number 11) to Sulfur (S, atomic number 16) using X-ray fluorescence (XRF) analysis, presents a notable challenge. Analyzing elements with atomic numbers less than 11 is nearly impossible. But what exactly makes light… View Article

Helium or Vacuum: What’s Best for Analyzing Light Elements? Characteristic X-ray radiation from light elements like sodium, magnesium, aluminum, and silicon is significantly absorbed by air, posing a challenge for analyzing these elements using desktop X-ray fluorescence (XRF) spectrometers. To enhance the analysis of light elements, XRF spectrometer manufacturers resort to either vacuuming the X-ray… View Article
