Chasing (macro)elements in microinvertebrates: a new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle Induced X-Ray Emission) applied to glacier tardigrades

Data related to the journal paper "Chasing (macro)elements in microinvertebrates: a new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle Induced X-Ray Emission) applied to glacier tardigrades" in MEE. The study focuses on the estimation of P content (%) per dry weight (and other low Z elements) in microinvertebrates using PIXE (Particle Induced X-Ray Emission) with the application of PESA (Proton Elastic Scattering Analysis).

All further details of this dataset are present within the study or will be gladly provided upon the request to the authors.
