[en] Understanding the hafting processes used during prehistory gives us an indication of the human technical capacity during those times. Hafting relies on adding a handle to a stone tool, often with the use of an organic glue (plant or animal based).1
Here dynamic headspace with two-dimensional gas chromatography coupled to a time-of-flight mass spectrometer (DHS-GCxGC-TOFMS) is applied for the characterization of pine resin and hide glue. The DHS parameters are optimized using a design of experiment approach. Several figures of merits were evaluated for quality assessment and the DHS method was challenged against an existing headspace-solid phase micro extraction (HS-SPME) – GCxGC-TOFMS approach.2
Generally, DHS was found more sensitive than HS-SPME, but the relative standard deviation was a little bit higher.
With this method a first step in a new, minimal invasive chemical identification method for prehistoric glues and resins is established. The DHS method was also evaluated against hide glue.
