Analysis of Fragrances by Multiple Detectors - FID and MS-TIC
Analysis of Fragrances by Multiple Detectors - FID and MS-TIC
The combination of an FID (Flame Ionization Detector), which has a wide quantitation response range, with an MS (Mass Spectrometer), which obtains qualitative information of unknown compounds, is suitable for analysis of natural product-origin samples, such as fragrances. Seen here is an example of simultaneous analysis of a fragrance with FID and MS (Split) using a detector splitting system.
In conventional analysis, a GC-FID and a GCMS obtain each chromatogram separately, and those data are compared. The detector splitting system enables users to obtain both a TIC (Total Ion Chromatogram) and FID chromatogram at the same time. As you can see with peaks A, B, and C, differences in retention times are one second or less with restrictors of appropriate inner diameter and length. From this analysis, the concentration of peak A is 0.13 % by FID, and it is identified as D-Limonene from a mass spectrum of peak A on the TIC. (See Fig. 2)
By acquiring abundant information at the same time, the detector splitting system saves both cost for analytical instruments and columns, and operators' time.
