Resolve, reveal, realize INTRODUCTION TO TECHNIQUE AND TECHNOLOGY Absolute Molecular Weight, Molecular Size The highest quality GPC/SEC measurement requires two things: • a good separation of the sample RESOLVE • sensitive detectors to characterize the separated sample - REVEAL GPC/SEC Separation As the dissolved sample flows through the porous column matrix, the individual molecules diffuse in and out of the pores. Larger molecules are excluded from more pores, and so travel through the column faster, eluting earlier while the smaller molecules elute later. The result is a separation by hydrodynamic...

Resolve, reveal, realize SYNTHETIC AND NATURAL POLYMERS Absolute Molecular Weight, Molecular Size, Structure Product performance Take control of polymer performance For both synthetic polymers and natural polymers, product performance is key to your success. For example: GPC is used in many industries as a development and QC tool. With a full understanding of your polymer’s characteristics: • If a polymer molecular weight changes from the specification, it may be too weak or too difficult to process • The polymer manufacturer can appropriately grade and sell their product • Poor control of PLA/PLGA...
