The aim of this study is the comparison of samples at dry and aqueous ambient conditions. Especially in biological and environmental sciences, x-ray spectromicroscopy is a powerful tool for investigating key questions, e.g., the study of structures in soil samples or cells showing dimensions on the nanoscale, concurrently gaining insight into chemical interactions. The spectral range around the C K-edge, in the so-called water window (285 eV – 523 eV), is especially well suited for the samples mentioned above, since it allows for working under aqueous and natural conditions. Exemplarily we present x-ray spectromicroscopy experiments of three different samples of high carbon content to demonstrate the importance of a sample environment as close to natural conditions as possible
