Mass Spectrometry

Abstract

and published researches covering the field of mass spectrometry continue to increase in scope and quantity. The nearly complete coverage of the field attempted in the previous review (SI) is discontinued because of space limitations. Cited references appearing in the interim through November 1955 are selected as representative examples of the diverse applications. Additional references, usually for particular applications, will be found in the several reviews and surveys cited below.

Analyses of Chromatographic Fraction of Organic Extracts of Soils

“…However, the temperature at which the hydrogenolysis of esters was performed in these studies and the high yields of saturated hydrocarbons obtained with only a nickel catalyst does not agree with earlier results (¿s'). The data presented for the benzene eluate fractions of sample 5 show that an essentially complete hydrogenolysis of esters will occur at 200°C. with a freshly prepared Raney nickel catalyst.…”

Chromatography. Analysis by Differential Migration

“…Several books (10,51,149,163) and reviews (50,63,79,135,178,179) are available. Numerous modifications and volatilization and ionization procedures may be found in Nuclear Science Abstracts.…”
