cool scifi idea: detecting and preventing time-travelers by measuring their isotope ratios and for presence of man-made isotopes.
combine this with the controversial practise of "banding": seeding the entire earth with trace amounts of isotope(s) with half-live(s) such that they will disappear in a few centuries, every few centuries. this ensures that time-travelers cannot jump out of their band and interfere.

the subject: accursed bottle of this terrible american lime vodka found half-buried in the scrubby woods of a friend's place when he bought it. weird, out of the way, rural.
gifted to somebody else recently, and despite all urgings it was tried. it tasted somewhat of dirt and cheap bad lime vodka.
what to do next? wtf is in this stuff. grab a pipette, sample phial, and another friend who has access to a GC-MS. https://en.wikipedia.org/wiki/Gas_chromatography%E2%80%93mass_spectrometry
A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.
