SAFELY WITH AIR SENSITIVE

John S. Hislop received his B.Sc. degree in Pure Science (Honours Chemistry) at Glasgow University in 1962 and his Ph.D. degree in the field of Physical Chemistry at the same University in 1965. He is at present carrying out a period of postdoctoral research as an assistant Research Chemist in the Activation Analysis Research Laboratory, Texas A&M University, College Station, where he has been concerned with the development of methods for the application of neutron activation for extraterrestrial surface analysis.

Richard E. Wainerdi is Head of the Activation Analysis Research Laboratory, Professor of Chemical Engineering and Associate Dean of Engineering at Texas A&M Uni­ versity, College Station, Texas. He received his B.S. in Petroleum Engineering from Oklahoma University in 1952, and the M.S. and Ph.D. degrees from Pennsylvania State University in 1955 and 1958. He attended the Oak Ridge School of Reactor Technology 1 9 5 5 - 5 6 , and came to Texas A&M in 1957 to develop a nuclear program for the Uni­ versity. He established the Activation Analysis Research Laboratory in 1957, and has been working in the areas of automated, computer coupled activation analysis including miniaturized systems since that time. He is a member of the Society of Analytical Chemistry and the American Nu­ clear Society. He has written a number of articles on various aspects of nuclear activation analysis.

GLOVE BAG is just the thing for safe handling of air sensitive materials. Flexible and easily purged, an inflated GLOVE BAG is 17" wide X 17" deep X 11" high, large enough for most ex­ periments (larger sizes are available). The gloves are integral—no accessor­ ies to buy—simply attach a cylinder of nitrogen and in a few seconds you have that dry, inert atmosphere you need! After use, deflate, fold up and save GLOVE BAG for another experiment, or discard it if contaminated. The price? An economical box of six for $13.95 (pluspostage)-specify GLOVE BAG model XX-17-17

Correction T h e Article " I n s t r u m e n t s and Analyses in the Vacuum Ultravio­ let," by J o h n Gilmore, ANALYTICAL CHEMISTRY,

38,

27A

(September

1966), contains the following state­ ment (column 3) paragraph 1, page 28A) : "A 40-cm. m o u n t is manu­ factured b y Tropel in Rochester a t this time. However, the m o u n t seems to be impractical in the vac­ u u m ultraviolet because of t h e re­ quirements of refocussing over a large wavelength range and main­

taining a vacuum during the pro­ cedure. These mounts are not me­ chanically viable with the vacuum ultraviolet." The author advises the editors t h a t this statement is in error and out of context. T h e T r o ­ pel spectrometer referred to is a Rowland circle radius m o u n t and is in focus for all wavelengths, and has been employed in much of the de­ finitive work on t h e alkali halides and the rare gases in the far ultravi­ olet.
