Result findig and presentation

Two fluidically independent collums for reference gas and sample gas are used.
Differences in temperatue and thermal conductivity occur between them and let to
changes in the electrical evaluation circuit which are analysed. It results in the "signal
mountain" known as the peak in the chromatogram. The figure below shows examples
of what chromatograms look like.

All the main gas components can therefore be recorded directly and can undergo
further processing.
