Preliminary investigation of differential tapelifting for sampling forensically relevant layered deposits

Highlights • Differential tapelifting does not enhance recovery of layered multi-donor deposits. • True for different tapelifting methods and combinations of deposit types. • An unexpectedly high amount of sample migrated through the substrate. • Findings are relevant to sampling strategies and prof...

Zusammenfassung:Highlights • Differential tapelifting does not enhance recovery of layered multi-donor deposits. • True for different tapelifting methods and combinations of deposit types. • An unexpectedly high amount of sample migrated through the substrate. • Findings are relevant to sampling strategies and profile interpretation. • More research is needed on substrate/sample interactions.
