SEC-MALS Testing for Molar Mass

SEC-MALS

SEC-MALS (Size Exclusion Chromatography – Multi Angle Light Scattering)

GMP/GLP Large Molecule Testing Services

With the growing number of large molecule products in development, it is more important than ever to be able to characterize your large molecule product with confidence.

That is why Dalton has added GMP/GLP Size Exclusion Chromatography – Multi Angle (Laser) Light Scattering (SEC-MALS) to its analytical services offering.

SEC-MALS is an established analytical method for the absolute determination of molar mass of large molecules. This approach is ideal for molecules with molar masses ranging from 103 to 109 g/mol, and is suitable for many molecule types such as:

  • Proteins
  • Peptides
  • Conjugates
  • Polymers
  • Biopolymers

SEC-MALS Advantages

SEC-MALS can replace a number of traditional techniques, such as viscosity, electrophoresis and retention times by HPLC, with a single absolute test.

  • Fast –Results in as little as one hour making it viable as an in-process test
  • Absolute – Molar mass is an absolute measure, not relative to a standard
  • Automated – Efficient and can process multiple samples quickly
  • Reliable – Precise and accurate molar mass results
  • Established – Accepted GMP/GLP test, no additional regulatory hurdles for validated methods
