Running three grams of that compound through a DCVC cycle using a set up like mine (small personal size) would reveal likely the different compounds evolving. It is unlikely you can find anyone that does this but I have found DCVC to be quite revealing in cases like this on a micro scale. I can envision the Q&A staff of larger companies adopting DCVC as a very fast tool for quality assurance.
If you ran this style shown in the link but instead just a few grams it is possible that the resolution and separation is even better than TLC.
