Rapid and Reliable Zinc Determination in Liquid Using a Compact Benchtop EDXRF

We introduce EDXRF analysis as a rapid and reliable method for Zinc determination in liquid solution. We demonstrated Zn determination at ppm levels using the calibration curve method with commercial Zinc liquid standard samples. Our calibration curve had a good linearity (R2 > 0.999) and we could accurately determine 22 ppm of Zn in 1 minute. The results demonstrated that EDXRF is an effective tool for rapid and reliable laboratory analysis.
