Paper chromatography, yes. But it is a once a year sort of deal. I test
my reds to ensure that mlf is complete before I consider bottling. In
my cellar, mlf usually gets going well soon after primary, but then
stalls during the winter (temps in the cellar drop to anywhere between
56 and 59). Kicks in again in the spring. But I always test later in
the year to be sure - before bottling.

Do you use chromotography to monitor your MLF?
