Ronald Belcher
Wins Gold Medal Pof the third
ROFESSOR RONALD B E L C H E R , winner
Gold Medal of the Society for Analytical Chemistry, was born in Nottingham in 1909. H e began his scientific career a t the University of Sheffield in the D e p a r t m e n t of Fuel Technology. After study in Austria under Hans Lieb in the Pregl Institute a t Graz, he became a Leverhulme Research Fellow in 1940-41 and subsequently became a lecturer on microchemistry. I n 1947 he joined P r o fessor H a r r y Melville's staff a t the University of Aberdeen as the lecturer in analytical chemistry and laid the foundation for his research school of analytical chemistry.
I n 1949 he moved with Prof. Melville to the University of Birmingham where he has been active in analytical chemical research ever since. I n 1959 he was made an honorary member of the Austrian Microchemical Society and began his work with the I U P A C . At Birmingham he built u p a large research team pursuing work in microchemistry, organic reagents, titrimetry, complexometry, submicrochemistry, spectrophotometry, atomic absorption, gas chromatography, kinetics, etc. I n 1959 he was appointed Professor of the first exclusive Chair of Analytical Chemistry in the U.K. T h e impact of Professor Belcher's group at Birmingham has had
a profound effect of the development of analytical chemistry in the U.K., Europe, Asia, and the U.S. Professor Belcher has published over 300 research papers, m a n y reviews, and several editions of six or seven textbooks. H e is a Past President of the International Union of P u r e and A p plied Chemistry's Analytical Division and is currently Vice-President of the Society for Analytical Chemistry. . T h e third Gold Medal honors P r o fessor Belcher for his m a n y contributions to analytical chemistry, not only in research, b u t also in influence in teaching and inspiring students to specialize in analytical chemistry.

...how these micro-flow valves enable you to precisely control very low liquid or gas flows m Our recently patented Models 150 and 151 Micro-Flow Valves are recommended for control of very low flows of gases or liquids. Suggested applications are in mass spectrometry, gas chromatography and high vacuum systems. A flow as minute as 0.25 cc./min. of air can be controlled. A fine screw permits twenty turns in 1/2" of total stem travel.The overall range in flow for this valve is at least 1000 to 1. The unique design permits a relatively low price.
