Dependence Of Calibration Curves Obtained From Gram-Schmidt Chromatograms From Experimental Parameters In CGC/FTIRS

The calibration curve for quantitative evaluation of Gram-Schmidt chromatograms (GSC) show a non-linearity in the low concentration region. Systematic experiments revealed, that variation in the baseline height in the GSC is responsible for a shift in the calibration curve. Summarized results are: (1) small changes of baseline introduce relative large errors; (2) this non-linearity must also be considered, when small peaks are measured which are not completely separated from a major one.
