    X-ray diffraction and scanning electron microscopy identified a 1mg sputum lith as calcite (rhombohedral calcium carbonate). These precise, non-destructive techniques offer broad applications for analyzing microcrystalline tissue deposits.

    Area of Science:

    • Analytical Chemistry
    • Mineralogy
    • Pathology

    Background:

    • Sputum liths are rare calcified deposits found in the respiratory tract.
    • Accurate chemical identification of such deposits is crucial for understanding their formation and potential health impacts.

    Observation:

    • A 1-milligram sputum lith was subjected to detailed chemical analysis.
    • Non-destructive analytical techniques, specifically X-ray diffraction and analytic scanning electron microscopy, were employed.

    Findings:

    • The sputum lith was unequivocally identified as rhombohedral calcium carbonate, specifically calcite.
    • The crystal structure and chemical composition were precisely determined.

    Implications:

    • The study demonstrates the utility of X-ray diffraction and scanning electron microscopy for analyzing microcrystalline biological samples.
