Send us Fan MailIn 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.
