To shred roughly or to grind? On the methods of sample preparation of the keratinous material for stable hydrogen isotope analysis

Hydrogen stable isotope measurement in keratin samples (hair, feathers, etc.) is one of the very popular, but rather complex tasks of isotope ratio mass spectrometry. The complexity of such analyzes is associated with the rapid contamination of samples with hydrogen from atmospheric moisture. The ef...
