The new HK Series Multi Detector GPC/SEC System from Testa Analytical Solutions eK combines high-performance chromatographic detector technologies and powerful, yet easy to use software to unlock the secrets of even the most complex synthetic polymers and natural macromolecules.
Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC) is widely accepted as the analytical technique of choice to characterise polymers and separate mixtures into fractions including polymer, oligomer, monomer and any non-polymeric additives. GPC/SEC is also the 'go-to' technique for characterising the molecular weight distribution of polymers.
However, increasingly widespread use of more complex synthetic polymers and macromolecules of natural origin such as proteins and peptides, requires advanced characterisation technologies to allow researcher gain a thorough understanding of their shape, structure and related physical properties. GPC/SEC systems combining measurements from multiple detectors not only provides increased amounts of data, but also information, which is available due to the combination of different detectors that would not be obtainable using the individual detectors separately.
