Paper Chromotagrophy for ML

I'm just now buying a paper chromatrography kit to determine malic, tartaric and lactic acid levels.

One of the main reasons I've not purchased one earlier is that I'm not sure whether or not there is any information that is actionable.

Is the kit just for the purpose of determing the rate of change or whether or not ML is occuring. Is the test to determine a baseline before ML and then find out if there has been any malic acid coverted, or if it is totally converted. In other words if you do test for ML progress and what action do you take once you've tested.

Your help on this is appreciated.

It's basically to determine that malic acid no longer exists in the wine. Usually you'll know anyway via secondary evidence: the pH has stopped rising, and no more bubbling is occurring in the wine.

To be really sure, you could send a sample to a lab - but that costs ~$20. If you have a thousand gallons that's probably advisable, and might even be worthwhile for a barrel's worth. Probably not for 5 gallons though.
