Learn to Select and Apply the Proper Internal Standard in ICP-OES

Choosing the right internal standard is critical to achieving accurate, reliable ICP‑OES results—but knowing how and when to apply one isn’t always straightforward. In this webinar, we’ll review the fundamental principles of internal standardization in ICP‑OES and provide practical guidance on selecting the most appropriate internal standards for different elements, sample types, and analytical challenges. You’ll learn how internal standards help correct for signal drift, matrix effects, and sample introduction variability, as well as common pitfalls to avoid. Through real‑world examples, we’ll demonstrate how proper internal standard selection and implementation can improve data quality, confidence, and consistency across both routine and more challenging analyses.
