In this episode, we tackle unexpected high recoveries, caused by internal standard signal timing during ICP analysis. Then we unpack a challenging multi-element blend, involving silver, tungsten, sulfur, rare earths, and more — plus how acid choices and order of addition impact stability. Finally, we dig into a sample prep puzzle for chloride analysis in iron phosphate, offering digestion strategies, matrix compatibility tips, and insights from Dr. Paul Gaines.

These real-world cases are packed with lessons to improve your prep, analysis, and problem-solving in the lab.
