Some sources of error in mass spectrometry have been investigated. It is concluded that with
the proper development, calibration, and photometry procedures and by applying the ap …

THE application of mass spectroscopy to the analysis of solids has become of great interest
within the last few years, and several different approaches to the problem have been made …

Although the mass spectrometer has been strikingly successful in recent years in the
analysis of mixtures of gases and vapors, there has been no parallel success in the routine …

The application of mass spectrometric technique to trace element determination in solids is
reviewed. Three techniques which show promise are:(1) the Dempster vacuum spark …

A vacuum lock for rapid introduction of solid samples into a mass spectrometer is described.
Analyses of the highest resolution requiring high vacuum can be made in five to ten minutes …

The mass spectrometer is an ana-lytical laboratory for charged par-ticles. Mass analyzers
commonly in use (magnetic, time of flight, quadru-ple, cycloidal, etc.) all derive their utility …

Three sequential computer programs have been developed for processing data obtained on
a high resolution mass spectrometer. Although designed for spec-tral data recorded on a …

CONCLUSIONS The upper limits inTable II provide useful information on the feasibility of
instrumental neutron activation analysis in six different matrix materials. Consider, for …

An integer resolution mass spectrometer-computer system has been developed in which the
computer controls the “scan” of a mass spectrometer. In this system, the computer queries …

A double-focusing mass spectrograph for the analysis of low concentrations of impurities in
solids has been developed. The instrument is of the Mattauch type and is designed for either …
