Dear Editor: In her article, K. Betts {Environ. Scii Technoll.1998 32(21), 487A-488A) reported ongoing research on the emissions of sulfur hexafluoride (SF6), which is notorious for its extraordinary… (More)
Measurements of carbonyl sulfide (COS) and carbondisulfide (CS2) were carried out on samples drawn from a smoke stack of an aluminium smelter. Volume mixing ratios of 6 ppm COS and 0.1 ppm CS2 were… (More)
BACKGROUND
There is a continuous process of development of new tonometer types following different measurement principles on the tonometer market. A new tonometer working on the dynamic contour… (More)
This paper describes a new strategy for the creation of chemically modified carbonaceous stationary phases. The strategy exploits the electroreduction of arenediazonium salts as a means for… (More)
Carbonyl sulfide is found as a major sulfur compound in anodic gases of commercial aluminium electrolysis. Recent spectroscopic measurements on industrial aluminium smelters found typical CO/COS… (More)
From July 1972 to December 1975, an unusual outbreak of diphtheria in Seattle, Wash., resulted in a total of 558 cases and carriers, mostly among heavy alcohol users. Skin infections were… (More)
