Radical approach is to rekristallize it and then dry at 100oC (boiling water bath) 
under high vacuum (both forvacuum and oil-boiler pumps) overnight. Certaily this days 
you might just use
thermal chamber set to 100oC instead of water bath. I presume that Aldrich TBAP is 
clean enough
so you might skip the rekristallization and just dry it.  Your signal is most probably
water.
