  • Dear Students!

    Welcome to the courses of the Chair of General and Analytical Chemistry. In order to make your studies easier, we have created e-learning courses for most courses, which we are constantly adding to and improving. With this in mind, we will do our best to accompany you on your way, if you follow suit, chemistry, despite all possible reservations, might even become one of your favorite subjects! 

    Good chemical luck, Thomas Prohaska and your team of supervisors!
