The Determination of Pb Tl Bi Ga Sn in High Purity Sulfuric Acid using Zeeman Graphite Furnace AA Application Note

Update: 29 September, 2023

This study outlines the methodology of using Zeeman graphite furnace atomic absorption (AA) for the determination of Pb, Tl, Bi, Ga, and Sn in high purity sulfuric acid. High purity acids are widely used in the semiconductor industry for various purposes. The study involved diluting 500 grams of high purity sulfuric acid to 1000 mL and analyzing unspiked and spiked samples for the five elements. The graphite furnace AA method provides the necessary sensitivity and precision to analyze metals at part-per-billion levels.
