Analysis of Espresso Aroma Profiles using vAPCI Compact Mass Spectrometry

This application note demonstrates the use of the Advion Interchim Scientific^® expression^® Compact Mass Spectrometer (CMS) with a volatile Atmospheric Pressure Chemical Ionization (vAPCI) source for rapid, direct analysis of espresso headspace. Aroma profiles from four commercially available coffee pods were compared using positive- and negative-ion vAPCI, highlighting the technique’s potential for fast aroma fingerprinting and product differentiation.
