and Wastgfuf Crystallizations? THEM TRf THIS "IONIC SOLVENT" AMBERLITE IRC-50 probably won't make all your present m e t h o d s obsolete. But there's n o faster, more selective means o f separating and concentrating inorganic and organic bases than this weak-acid cation exchange resin. (And don^t rule o u t ion exchange j u s t because t h e base you're trying to capture is in an organic solvent. AMBERLITE IRG-50 h a s a good record t h e r e , too.) Next time you s a y to yourself "There m u s t be a better w a y " to recover valuable metals or to separate antibiotics, vitarr&in^ alkaloids,
amino acids, and other
obstinate bases, j o t down y o u r problem—and send it to Dept. C E I - 4 You'll receive suggestions a n d technical literature that m a y h e l p you save time, simplify your process, a n d increase y o u r yield with AMBERLITE IRC-50»
