THE NEW LEVEL OF PERFORMANCE FOR POLYMER CHARACTERIZATION. A NEW LEVEL OF CONFIDENCE FOR YOU.

It's time to take a fresh look at polymer characterization. Chances are, you've never seen

anything like this before. That's because the Waters® Alliance GPC System can determine

MW values with previously unattainable precision. So you'll have greater confidence in your

results. And when you see molecular weight distribution differences between samples, you

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,
