Law enforcement personnel can now quickly and safely detect street drug W-18 and other lethal drugs with the newest library update for the Thermo Scientific TruNarc handheld narcotics analyzer. W-18 is a new designer drug considered to be significantly more potent than morphine and fentanyl. As part of its most recent v1.6 software update, the TruNarc analyzer adds dibutylone, furanyl fentanyl, and U-47700 to its onboard library, which now includes nearly 300 suspected narcotics and narcotics precursors and an additional 80 common cutting agents. The TruNarc analyzer lets you scan a single sample for multiple narcotics in one test and receive results within seconds.
