Originally produced as a legitimate pain killer, the Fentanyl molecule is extremely potent and 100 times stronger than heroin. Due to the widespread adoption of Fentanyl, synthetic opioids and other pharmaceutical based agents, first responders are likely to come into contact with these highly toxic substances. Providing a rapid diagnostic tool is critical to ensure the safety of the operators on the frontline. Working with the AP4C detector, the S4PF sampler allows the collection and vaporization of certain narcotics in order to perform quick detection on the field. The SP4F sampler is available in selected AP4C kits or can be offered as an add-on to Proengin users who wish to extend the capacity of their existing AP4C kits.
