The retention times are calculated from the moment the sample is injected
in the chromatographic column (IT FLASH1). In the chromatogram, this
corresponds to the first peak observed in time, which is generated by the
flash heating of the injection trap of SAM-GC. This time is 
422943315.96 s (sclk) for this chromatogram. The retention time is 
calculated by subtracting this time, to the times of the peaks maxima.

The abundance given in the table corresponds to the area of the peaks which
are measurable. These surfaces are proportional to the amount of the species
detected when a peak is eluted. When peaks are co-eluted (over of different
peaks), the peaks are fitted using a gaussian function. If the fit does not work, 
only one surface value is given, corresponding to the sum of the
abundances of the species contributing to the peak.The areas are calculated
using a trapezoidal rule, after a baseline subtraction.
