News Now you can get pre-tested capillary columns (WCOT, SCOT, Micro-Packed) for high resolution gas chromatography in stainless steel or glass... with df of 0.2 and 0.4 micron, and, if desired you can specify your own film thickness. The SS wall-coated col umns with 2000 to 4000 plates per meter are available in any length with any liquid phase. The wall-coated glass columns with 3000 to 6000 plates per meter are avail able standard in 25 and 50 meter lengths and 0.25 or 0.50 mm ID, with.eight liquid phases. Other stationary phases also available. All pretested and supplied with test chromatogram, report, sample, and extensive instruction bulletin (written so that even inexperienced users can start using high resolution chromatography). Chrompack Laboratories are dedicated to manufacturing col umns, with 10 years experience in Europe making capillary columns. Write for a free catalog to Chrompack, RO.

ANALYTICAL CHEMISTRY, VOL. 5 1 , NO. 6, MAY
Douglas Stewart Russell, head of the analytical chemistry section of the Division of Chemistry of the National Research Council in Ottawa, Canada, has been named winner of the Fisher Scientific Lecture Award for 1979. He will present his award lecture on trace analysis at the 62nd Chemical Confer ence and Exhibition in Vancouver, June 3-6,1979. Mr. Russe! ι was born in Georgetown, Ontario, in 1916, and graduated in chemistry from the Uni versity of Toronto. He started his ca reer with Welland Chemical Works and then served as research officer in radiochemistry for an atomic energy project. He joined NRC in 1946 and became head of the analytical section in 1952. He served on the editorial board of Chemistry in Canada, on the executive committee of the CIC Ana lytical Chemistry Division, and was national president in 1969 of the Ca nadian Spectroscopic Society. The Fisher Award, sponsored by Fisher Scientific Co., Ltd., is accompa nied by a scroll and an honorarium of $1000. It is awarded to a scientist liv ing in Canada who has made a distin guished contribution in analytical chemistry while working in Canada.
