Chemist at Polymer Char

Esther López joined Polymer Char in 2011, and since then she has been working in the analytical laboratory department focusing on polyolefin characterization by high-temperature GPC, her main area of expertise. She has also worked with other separation techniques such as TREF, CEF, TGIC, CFC, and SGIC 2D.
She is a technical specialist with solid experience in engineering, development, and validation of chromatographic methods applied to polymers, quality management and continuous improvement of existing techniques and equipment. She has extensive international experience in technical support, training, and product development through her more than ten years of experience.
Esther received a Bachelor’s Degree in Chemical Engineering from the Polytechnic University of Valencia, Spain, and a Master’s Degree in Analytical Chemistry from the University of Valencia.
