Mastering Geological Sample Preparatione

Learn the strategies for Complete Digestion and Low Blanks

Preparing geological samples for elemental and isotopic analysis can be challenging. From silicate rocks to matrices containing resistant minerals, achieving complete dissolution while maintaining low blanks is essential for reliable trace and ultra-trace results. Yet traditional digestion methods can be slow, prone to contamination, or ineffective with refractory matrices.

Milestone has the solution: the SRC technology achieves complete digestion across diverse geological matrices.
Through practical examples and digestion guidelines, Milestone can guide you to achieve complete digestion, reduce procedural blanks, and simplify your laboratory workflow.


Read the Handbook “Efficient rock digest preparation for geochemists”

The practical handbook features a scientific overview of the digestion challenges associated with silicate-rich, refractory, and HFSE-bearing rocks, along with method development strategies.
With the cooperation of Professor Balz Kamber of Queensland University of Technology, we introduce practical insights and comparative data on microwave digestion approaches, with a focus on Single Reaction Chamber (SRC) technology. Key topics include reproducibility, blank control, reagent reduction, and compatibility with HF mixtures.
Additionally, we showcase a newly proposed framework for categorizing geological matrices to simplify digestion protocols, reduce consumables, and promote method consistency across research groups.
