So I'm staring at the results from a MLF test and I'm wondering if
there's a faint indicator of malic acid or it's just the lights.
Paper chromatography seems very qualitative - I'm 90% sure that malos
are complete as I don't see any dots for malic acid, but it's all very
blue/yellow/green and fuzzy. Even the testing documentation stated
that when there is no longer any dot there still may be some malic
acid left. When does one declare victory?
