Since 1839 - professor of chemistry at the Kazan university. Since 1852 - professor of pharmacy at the Derpt university. Klaus's works on research of platinum metals, begun in 1840, are widely known. He established structure of the rests of the Ural platinum ore received after its dissolution in Tsar vodka; found ways of transformation of platinum metals in solution, developed new methods of division of platinum metals and ways of reception of them in the pure state, received many of chemical compounds for the first time . In 1844 Klaus discovered in the rests of the Ural platinum ore the new element and named it ruthenium (from Lat. Ruthenia - Russia). Klaus received ruthenium in the pure state, studied its chemical properties and defined its nuclear weight. Works of Klaus had a very important value for creation of the platinum industry, especially for development of methods of reception in the pure state of iridium, rodium, osmium and ruthenium.
