Differential analysis of coffee aroma compounds using HS GC-QMS and msFineAnalysis iQ
MSTips No. 363
The msFineAnalysis iQ is an automated qualitative analysis software for gas chromatograph quadrupole mass spectrometer JMS-Q1500GC / JMS-Q1600GC that performs integrated analysis combining library database (DB) search results using EI (Electron Ionization) mass spectra and molecular weight information using soft ionization methods. In addition, the software provides automatic peak detection by deconvolution, differential analysis of two samples, and qualitative analysis by retention index (RI). Using this software, a more accurate qualitative analysis can be achieved in a shorter time.
Coffee aroma contains a very large number of components. Therefore, a large number of peaks are observed in TIC chromatogram, and it takes a long time to identify the components of each peak and to analyze differences between samples. In this report, we present the results of differential and integrated analyses performed on coffee aroma components using msFineAnalysis iQ.
