can rest assured that they are true differences—not the result of slight instrument variables. The smooth, pulseless flow of Alliance is key to this dramatic increase in performance. And Alliance consolidates solvent and sample management operations into a single, compact system. For more evidence of how Alliance™ GPC Systems are topping all the charts, call us at 1-800-252-4752,
