ToF-SIMS spectra of caffeic acid, vanillin, eugenol, and cellulose in positive polarity

Abstract: Initially used for fermentation or storage, oak wood barrels were found to enhance the organoleptic properties of spirits. Over time, wood compounds have been linked to the quality of the spirits. ToF-SIMS being an ionization technique that produces intense fragmentation patterns which are not fully understood, reference spectra are required to confidently analyze wood samples. Here, positive polarity ToF-SIMS reference spectra of important oak wood compounds being involved in spirit maturation, using a Bi3+ primary ion species, are presented.
