INSTALLATION FOR SIMULTANEOUSLY DETERMINING THE PARAMETERS OF PHOTODEGRADATION AND ADSORPTION PROCESSES IN THIN LAYERS

摘要

The invention relates to an installation for simultaneously determining the parameters of photodegradation and adsorption in thin layers. According to the invention, the installation comprises a cylindrical metal enclosure () having the walls covered with a reflecting foil () on which there are radially arranged six fluorescent tubes () supplied through separate electric circuits () for controlling the luminous intensity, a central quartz tube () provided at the ends with some threaded parts () which are tightly closed with some plugs () having some connections () for hoses (), the lower tightening plug being provided with a specimen fastening system consisting of some tracks () fixed in a system () allowing the immobilization of the thin layers during the test.
