             Analytical Services




The Chemistry Department at Durham University is one of the leading
Chemistry departments in the UK and has a variety of exceptionally
well-equipped research services. As part of the Interdisciplinary Research
Centre in Polymer Science and Technology (Polymer IRC), Khosravi’s
laboratory offers services aimed at materials characterisation including
water content analysis, viscosity measurement and scaling-up facility.
