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 405359252 s (sclk) for this chromatogram. The retention time is calculated by substracting this time, to the times of the peaks maxima. Peak 0 ; IT FLASH1 ; 0 s Peak 1 ; ; 184 s Peak 2 ; ; 218s Peak 3 ; BENZENE ; 252 s Peak 4 ; TOLUENE ; 313 s Peak 5 ; ; 331 s Peak 6 ; ; 341 s Peak 7 ; ; 438 s Peak 8 ; ; 599 s Peak 9 ; IT FLASH2 ; 940 s Peak 10 ; ; 1159 s 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), 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 substraction.
