(Wooden Artifacts) Separating the Three Species of Swietenia spp. in Rhode Island Furniture Using Direct Analysis in Real Time – Time-of-Flight Mass Spectrometry

Separating the species of Swietenia spp. using traditional wood anatomy has been difficult since the cell structure of all three species is not diagnostic and the color and density overlap. Wood samples were taken from sixteen pieces of 18th C. American furniture made in Rhode Island, all in the collection of the Yale University Art Gallery along with seven samples from the author’s collection. This study compared heartwood chemotypes of 34 samples using Direct Analysis in Real Time – Time-of-Flight Mass Spectrometry (DART-TOFMS) to a known database. Results indicate that all three species of Swietenia spp. can be reliably separated and all three species were found in Rhode Island furniture made in the 18th C.
