Molecular weight

Absolute molecular weight determination and measurement of molecular weight distribution.

The molecular weight of proteins, synthetic and natural polymers is a direct indicator of product performance and activity.

Applications of molecular weight

Understanding molecular weight determination, absolute molecular weight measurement and other molecular parameters is key to controlling product performance in a wide variety of application areas including:

  • Strength, durability and toughness of plastics and other synthetic polymers
  • Degradation and release rate of drug delivery polymers
  • Performance and mouth-feel of polysaccharides in foods e.g. maltodextrin and other starch derivatives
  • Strength and quality of fillers and lubricants in pharmaceuticals and cosmaceuticals e.g. hyaluronic acid and cellulose derivatives
  • Efficacy and aggregation state of proteins and biopharmaceuticals e.g. monoclonal antibodies (mAbs)
