Research

In the Department, routine analyses utilizing standard analytical procedures and instrumentation are performed to characterize the products investigated by the Institute staff.

New analytical procedures for specific materials are proposed and verified to obtain reliable results supporting research activities of the Institute and quality control of products for industry and business, e.g. benzene and off-odor substances in wrapping foils.

In research activities, attention is focused on the application of advanced analytical methods for the identification and determination of both major and trace components. Utilization of solid phase microextraction (SPME) together with GC-MS allows to analyse volatiles and semivolatiles in a broad spectrum of polymer materials and products.

Identification of polymers in collections and objects of cultural heritage to propose proper methods of their maintenance and preservation is performed for public and private institutions.

In 2000, a new method, dynamic characteristic of bipolar membranes was elaborated and presented. The method allows a chronopotentiometric aspect to be involved in the volt-ampere characteristics. The theory of the oriented concentration potential of asymmetric membranes has been extended to all known types of membrane asymmetry. The methodology for evaluation of proton conduction in membranes has been developed.
