Together with his colleague from the University of Graz, Fritz Pregl he perfected the work in small scales analysis.

He received his PhD in 1884 and after teaching in a school for a short period he handed in his habilitation in 1888.

In the following years Emich was able to introduce several new methods into chemistry which were essential for working in small scales.

Emich improved the quartz fiber balance and he introduced capillary pipettes to handle small amounts of liquid for analysis.

After the publication of his second book Mikrochemisches Praktikum in 1924 he spent considerable time teaching visitors to Graz University of Technology his new methods.
