GPC/SEC Systems

Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC) is the technique of choice for rapid and reliable characterization of molecular weight and molecular structure for all types of macromolecules – proteins, natural polymers and synthetic polymers.

Proteins
•Absolute molecular weight
•Oligomeric composition and aggregation
•Protein size and density
•Conjugate composition
•Second virial coefficient

Polymers
•Absolute molecular weight
•Molecular weight distribution
•Branching and structure
•Molecular size
•Copolymer composition

Whether you are looking for a complete system or an additional detector to enhance your existing system, Malvern offers the most comprehensive range of products for all your macromolecular GPC/SEC characterisation needs. At the heart of this range are the Viscotek advanced GPC/SEC systems, including the powerful TDAmax system with OmniSEC software.

GPC/SEC Systems:

Viscotek TDAmax - Integrated, temperature controlled GPC/SEC system
The Viscotek TDAmax is a complete, temperature controlled, advanced, multidetector GPC/SEC system suitable for all macromolecular applications, particularly research. It consists of three unique and complementary components – The Triple or Tetra Detector Array (TDA), the GPCmax integrated solvent and sample delivery module and the OmniSEC software.

Viscotek 270max - Modular, ambient temperature GPC/SEC system
The Viscotek 270max is a modular advanced multi detector detector system that operates at ambient temperature. It is perfect for the routine full characterization of natural and synthetic polymers, copolymers and proteins.

Viscotek RImax - Modular, conventional GPC/SEC system
The Viscotek RImax is a modular, conventional calibration system. It offers simple operation and full upgradeability to advanced detection. Designed for routine GPC/SEC and teaching purposes. Operates with the same powerful OmniSEC software as used in the advanced systems.

Protein SEC-LS detector:

Zetasizer µV - SEC-LS detector for protein analysis by SEC
The Zetasizer µV is a modular DLS/SLS detector with dual integrated light scattering capability offering superb performance in both SEC-LS and cuvette mode.

High temperature system for polyolefin analysis:

Viscotek HT-GPC - For polyolefin analysis
The Viscotek HT-GPC is a modular high temperature GPC system designed specifically and exclusively for the characterization of polyolefins at up to 160°C.
