Chemir recently acquired new Gel Permeation Chromatography (GPC) techniques to apply for detailed analysis and problem solving of plastic and polymers. The newest techniques continue to expand Chemir's capabilities to characterize polymers for failure analysis, product comparisons, contamination issues and other investigations.
The new Agilent 1260 Infinity GPC/SEC System allows for polymer molecular weight (MW) characterization at high and low temperatures on most polymer / solvent combinations. The instrument includes a powerful trio of detection systems - refractive index, viscometry and dual-angle light scattering. These detectors allow determination of a polymer's absolute molecular weights as well as details associated with polymer branching.
"We are excited to have another new tool for polymer characterization," says Christopher Andren, Technical Specialist of Chemir. "This continues to expand our ability to help companies answer challenging questions regarding their polymeric materials." The purchase of the new GPC is in-line with the laboratory's 2013 growth plan, which includes a newly renovated synthesis laboratory, extensive building improvements, the addition of four scientists and the acquisition of additional analytical instrumentation.
