So like I know in atleast American airports you can get randomly selected or if your bag is searched they run a little swab on your hands or stuff. They say it’s for explosives residue which makes sense to check for but how do these tests work?
It seems like explosives could be made out of a huge variety of things that are accessible. Two easy ones that come to mind are gunpowder and gasoline. What test shows all the main potential explosive ingredients? Or do they just only check for a couple?

I tested positive on one of those swab test at the airport. My hand lotion had glycerin in it. It’s a very common additive in lotions.
