I travelled through the US from Mexico to Europe last year. Bought a nice bottle of Mezcal at the airport in Mexico, had it in a sealed bag to enable travel. TSA agent didn't trust the travel seal, so he took it out of the bag, scanned bottle with some cotton swabs put into a device (my guess is HPLC), it was OK so he re-sealed my bag with TSA tape so I could carry it on multiple flights in Europe.
