Breakthrough Technology Ushers in the Next Era in Polymer Discovery
Apr 19 2013
Waters Corporation have announced a system that defines a new category of chromatographic polymer analysis, yielding improved molecular weight information about polymeric species, faster than ever before. The system delivers dramatically improved polymer peak resolution, particularly for low molecular weight polymers and oligomers up to 20 times faster than traditional gel permeation chromatography (GPC).
The ACQUITY® Advanced Polymer Chromatography™ (APC™) system was unveiled at Pittcon and was developed in collaboration with The Dow Chemical Company.
APC is comprised of an innovative, refractive index detector that has been optimised for low dispersion but with the low noise and drift performance required for accurate integration, even at low polymer concentrations.
The precise flow delivery of the isocratic solvent manager ensures that the calibrated system delivers accurate molecular weight data, day after day. Additionally, the system features new column technology based on rigid, sub 3µm, high pore volume bridged-ethyl hybrid particles that provide significant gains in stability and faster separations.
Ian King, Waters Vice President of Separations Technologies, noted that APC represents a major change from soft gel columns that are susceptible to swelling in the solvents used for polymer analysis.
“With APC, scientists can run diverse polymer applications on a single system, on one bank of columns with a variety of solvents,” he said. “Now our customers can significantly improve laboratory efficiency and asset utilisation. This collaboration with Dow is an example of what can happen when you merge leading edge technology with excellent innovation and effective collaboration.”
