Thoughts about high chlorine peaks in X-ray microanalysis.

C H Becker

    Experientia
    |August 15, 1979
    PubMed
    Summary

    High chloride (Cl) peaks in biological tissue analysis suggest this element originates from the tissue itself. This finding may enable rough regional estimations of chloride levels in biological samples.

    Area of Science:

    • Biomedical science
    • Analytical chemistry
    • Microscopy

    Background:

    • X-ray microanalysis frequently reveals high chloride peaks in biological tissues.
    • The source of this observed chloride is often unclear, potentially stemming from the sample or embedding medium.

    Purpose of the Study:

    • To investigate the origin of high chloride peaks observed during X-ray microanalysis of biological tissues.
    • To assess the feasibility of using chloride levels for regional estimations in biological samples.

    Main Methods:

    • X-ray microanalysis of biological tissues embedded in epoxy resin.
    • Comparison of chloride peak intensities within the tissue versus the surrounding epoxy environment.

    Main Results:

    • Consistently observed high chloride peaks in biological tissue samples.
    • Chloride peaks were significantly higher in the tissue compared to the epoxy embedding medium.
    • This suggests a substantial endogenous source of chloride within the biological tissue.

    Conclusions:

    • The majority of chloride detected in X-ray microanalysis of biological tissues originates from the tissue itself.
    • This endogenous origin of chloride opens possibilities for rough regional quantification of chloride levels in biological samples.
