In terms of impact and friction sensitivity for both peroxides a content of 40 wt-% resulted in >30 Nm impact sensitivity and >360 N friction sensitivity. Both phlegmatized peroxides passed the Koenen Tube and Thermal Stability Test according to the UN recommendation on the transport of dangerous goods test manual. Investigations with a process mass spectrometer indicate that d40-TATP can produce a saturated TATP headspace at least in the same time as the same amount of pure TATP. Measurements with the transpiration method demonstrated that the vapor pressure (Formula presented.) at 298.15 K of d40-TATP (2.3 Pa) and d32.7-TATP (0.9 Pa) is lower than that of pure TATP (6.7 Pa). Headspace SPME-GC/MS measurements revealed that the active charcoal does not contribute to the vapor profile of the training aid. Both d40-TATP and d10-HMTD were tested as training aids for explosive detection dog teams (EDD). In both differentiation track and realistic environment scenarios a detection rate of 100 % could be achieved by German Federal Police EDD with a false positive rate of solely 3 %.enCanine Training Aidexplosive detectionExplosive Detection Dogsperoxidesvapor pressure660662journal article
