REPORT FOR ANALYTICAL CHEMISTS
Advances in instrumentation have been accompanied by equally substantial progress in providing adequate facilities for analytical research, development, and testing. Shown at top is General Electric Company's standardizing laboratory at Schenectady in 1897. Below is the way GE's research laboratory near Schenectady appears today. The main building is in the foreground and the metals and ceramics building near the water tower
seemed to be tha t the well of new discoveries in inorganic chemistry had run dry. Before the trend had fairly gotten started, however, the development of new products and processes started bringing about a need for better methods of analysis and control.
Friedrich Emich's microchemical work from 1900 onward established him as the founder and pioneer of the science of microchemistry (1). In 1911 his "Lehrbuch der Mikro-chemie" was published and the outline of microchemistry was established, mostly on the basis of ex
perimental work of Emich and his assistant, Julius Donau.
In 1910, Fritz Pregl—like Emich, an Austrian from Graz—-investigating the bile acids, found occasion to extend the use of microchemical methods to the organic field (2). He continued his interest in organic micromethods, and his efforts in developing them were recognized through a Nobel Prize in Chemistry presented to him in 1923. His text on the subject helped to stimulate interest throughout the world, and by the time the third edition of "Quanti tat iv Organische Mikro-
