The fundamental principles of mass spectrometry were established at the turn of the century
in a series of classical experiments by, inter alios, Wien, l and Thomson. 2 These workers …

The technique of high resolution mass spectrometry has presented rather formidable data
acquisition, reduction, and presentation problems. In our efforts to make the task more …

The principles, techniques, instrumentation, and applications of high-resolution mass
spectrometry are reviewed and illustrated by examples of studies on organic compounds. A …

The paper gives details of four years' experience in operating a high resolution (up to
10,000) mass spectrometer on problems of organic chemical analysis. Desirable features in …

The chemical formula of an organic ion can be determined by a sufficiently accurate
measurement of the mass. Consideration of the various doublets which can be produced by …

Historical.-Positive rays were discovered by Goldstein in 1886. In experiments on the
discharge of electricity through gases at low pressure, he used a perforated cathode and …

The capabilities of high resolution mass spectrography using Ilford Q2 and Technical
Operations evaporated AgBr photographic plates as ion detectors are dis-cussed. The …

This retrospect traces the development of commercial mass spectrometers for use in the
petroleum industry, starting with the formation of Consolidated Engineering Corporation in …

Molecular ion distributions are calculated and presentedfor three sets of homologues with
different elemental compositions and hence different mass defects and isotopic distribu-tions …
