Abstract. We present XMM-Newton data of several RS CVn binary systems. High-resolution X-ray spectra obtained with the
Reflection Grating Spectrometers have been interpreted simultaneously with the European Photon Imaging Camera spectra.
Highly active stars show a depletion of elements with a low first ionization potential (FIP) relative to high-FIP elements,
