A new developed photodiode array (PDA) detector for the TDAmax gel permeation chromatography system from Viscotek provides polymer scientists with a powerful and flexible tool for the rapid analysis of multi-component matrices. Gel permeation chromatography (GPC), also known as size exclusion chromatography (SEC), is widely used to characterize natural and synthetic polymers, copolymers, proteins, nanoparticles and other macromolecules. The TDAmax is a comprehensive GPC/SEC system with an integrated triple or tetra detector array. By capturing absorption spectra across the UV-vis wavelength range, the PDA detector provides a fingerprint of each ‘time slice’ of the sample as it elutes from the column. This is especially valuable for the detailed study of copolymers, blends and mixtures containing unreacted monomers or oligomers. Measurement times are just 30 to 40 min., making the system highly productive. The PDA detector captures data across the range 190 to 500 nm, allowing users to select wavelengths of interest after the analysis has been carried out.
