Because organic geochemistry does not seem to follow a simple mixing model, endmember concentrations cannot be calculated. To that respect composition of the purest fluids is presented and assumed to be close to endmembers composition. Note that quantitative results are not available for the Kulo Lasi fluids (see Figure <a href="../fig6/">6</a> for chromatograms).</div>
