Abstract [en]

A new freeze-substitution method using tetrahydrofuran (THF) as organic solvent was tested in the preparation of pancreas for determination of elemental content and distribution. Particle induced X-rayemission (PIXE) allowed analysis at the cellular level and X-ray microanalysis (EPMA) at the subcellular level. Using PIXE allowed detection of Zn, Ca and Fe, not detectable in the EPMA spectra. The ratios of Cl and K to P and to S obtained from analysis using both PIXE and EPMA agreed well. A good preservation of the in vivo ionic content was manifested in high K to Na and K to Cl ratios.
