HF-Free Sample Preparation: Safer Strategies without Compromised Digestion Performance

Hydrofluoric acid (HF) has long been used for the digestion of silicate and other difficult matrices, but its extreme toxicity and handling risks make it one of the most hazardous reagents in the laboratory. Reducing or eliminating its use can significantly improve laboratory safety and simplify compliance.

This webinar will demonstrate how advanced microwave digestion systems enable complete sample decomposition without relying on hydrofluoric acid. By leveraging higher thermal and pressure capabilities, laboratories can achieve effective breakdown of challenging matrices using safer acid combinations while maintaining analytical integrity.

Through practical examples, we will show how HF-free methods can deliver reliable recoveries, clean solutions, and reproducible results for ICP-OES and ICP-MS analysis.

Key Learning Objectives:

  • Recognize the safety and compliance risks of using HF
  • Understand how higher temperature and pressure enable HF-free digestion
  • Identify safer acid alternatives for challenging matrices
  • Assess performance of HF-free methods for ICP-OES and ICP-MS
  • Apply practical strategies for safer digestion workflows
