Digestion
Intended Learning Objectives
1. Prepare quartz samples for cosmogenic isotope analysis by accurately weighing and adding Beryllium 9 and Aluminium 27 carriers to ensure detection limits are met for AMS measurement.
2. Safely conduct hydrofluoric acid digestion by following laboratory safety protocols, wearing appropriate PPE, and monitoring reaction progress to ensure complete sample dissolution.
3. Process and purify digested samples through evaporation, re-dissolution, and conversion to chloride form, ensuring readiness for anion exchange chromatography.
