An automatic system makes possible the rapid and ac-curate preparation of element maps
from high-resolution mass spectra recorded on photoplates. By meas-uring transmittance …

A significant reduction in the number of possible formulas corresponding to peaks in a high-
resolution mass spec-trum is achieved by converting the isotopic formulas to a single …

A system is described in which a medium‐sized double‐focusing mass spectrometer is
coupled on‐line to a small (4K memory words) computer. The system can produce complete …

A computer program which analyzes low resolution mass spectra of organic compounds of
molecular weight less than 200 is described. The program operates ab initio, that is, it does …

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 …

Computer aided mathematical techniques for the improvement of mass spectrometer data
resolution are pre-sented and discussed. Assuming that an output spectrum consists of a …

CONCLUSION If a catalog of complete mass spectra can be stored, the problem of retrieval
and identification of a given spectrum is almost a trivial one. Even when using the ASTM …

A technique has been developed whereby high resolution mass spectra may be readily
obtained from fast magnetic scans of gas chromatographic effluents. With resolving powers …

In recent years, the popularity ofthe combination gas chromatograph-mass spectrometer
(GC-MS) has increased markedly. This is due, inpart, to the more stringent regulations set …

A system is described in which computer techniques are used to carry out major steps in the
procedure for interpretation of high‐resolution mass spectral data. These steps include …
