There he concentrated his work firstly on the determination of vapour density in solutions of inorganic compounds and later he was engaged in researches into the chemistry of colloids.

[2][3] He gained further scientific and practical experiences in the university research institute of Clemens Winkler in analytical and inorganic chemistry and later in Metallurgy in Göttingen with Gustav Tamman.

During these years he also investigated the influence of temperature on the properties of non-metallic systems as for example Polysulfides of Rubidium and Caesium by the use of thermal analysis.

Despite attempts by Biltz to recover the tank, damage to the engine forced demolition crews to blow it up on the night of 23–24 April.

Furthermore, he was an academic author of the ‘journal for inorganic and general chemistry’ for many years until his early retirement due to impaired health.
