Various nitrates are often used in the making of explosives (e.g., trinitrotoluene, a.k.a. TNT) and they're checking to see if you've been handling any recently. I find it interesting that they were checking hands—perhaps that's more accurate than some of the other sampling sites they've used in the past.

Can you see a tampon during an airport body scan? This is a frequently asked question on Google, and if it's something you're worried about, you can breathe a sigh of relief. Airport body scanners can't see inside the body and therefore can't detect a tampon on a TSA female body scan image.

The TSA largely looks for physical evidence that a passenger could be a threat, so they'll generally have no reason to search through the data on your phone. After all, they're the Transportation Security Agency, not a detective agency. Even if they did have reason to want to access your phone, they'd need a warrant.
