This application note demonstrated the correlation coefficient (R2) > 0.99 from 26 fragrance compounds analyzed by a CDS Analytical 7000C concentrator equipped with a dynamic headspace (DHS) module. This setup was mounted on a PAL RTC rail and connected to a GC/MS for compounds separation and detection.
In the previous study, a CDS Analytical 7000C concentrator with an optional DHS module was used to perform fragrance profiling study. An average RSD = 2.8% (n=8) was observed from 26 fragrance compounds. Interestingly, the result was showing that the response factor from the DHS module is two times higher than the direct GC injection method. This application paper is a continuous study after the previous work. The experimental design focused solely on obtaining calibration curves from the same 26 fragrance compounds to show the system is qualified for quantification studies.
