I'm trying to set up a method to quantify gluconic acid in wine trough CE, I found a nice publication winch use as electrolyte 5mM b-resorcylic acid in 0.5% methanol, pH3 and 1mM TTAOH.
Now that problem I'm having is find the TTAOH, looks like is impossible called all the supplier but nobody have it! I found TTABr, for my understanding this is a flow modifier during the analysis, using the Br instead of OH could have a big impact?

Any suggestion or idea?
