No internal standard on the instrument (it failed). The linked article says that they found nitrogen-containing heterocycles that are “similar to precursors of DNA” but that’s a pretty big stretch. There’s a lot of stuff in there that they just don’t identify.
I think a lot of this stuff is consistent with what you’d get if a carbon- and nitrogen-containing meteor hit the surface. Definitely not a slam-dunk for life, and not really even close, unfortunately.
