This episode takes a fun detour into the world of chemistry conspiracy theories! Mike Booth explores the science behind chemtrails vs. contrails and explains how you could actually test for elements like aluminum, barium, lead, and lithium in air samples using ICP-OES and ICP-MS. Learn practical tips for sample collection, how to avoid common interferences, and why trace analysis requires extra care with contamination control.

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.

In this episode, we dive into two real-world stability challenges from our lab. First, we explore a custom tune solution prepared in dilute ammonium hydroxide for ICP-MS, designed to improve lab efficiency. Learn how it performed over time and how to use it effectively for short-term use. Then, we dig into an unexpected silver instability in a low-level multi-element blend — traced back to residual chloride from chromium prep.

From method design to trace contamination troubleshooting, this episode is full of practical lessons for anyone working with custom solutions or chasing long-term stability.
