Heated Sample Inlet System for Mass Spectrometry

Early gas chromatography/mass spectrometry

“…Here a vigorous research program had already developed important instrumental analytical techniques, such as xray diffraction, atomic emission, and infrared absorption spectroscopy, applicable to a wide variety of the company's problems. Its Director, Norman Wright [12], and the Group Leader, [ason Saunderson, had also encouraged similar mass spectrometry research with two Westinghouse mass spectrometers partially constructed by Victor Caldecourt [13]; these instruments and a CEC 21-1036 were applied to a variety of chemical problems [14][15][16][17].…”

Mass Spectrometric Analysis. Aliphatic Nitriles

“…The spectra were obtained on 90°s ector-type instruments whose inlet systems (4) were maintained at 200°e…”

Billionfold data increase from mass spectrometry instrumentation

“…Improvements in research and commercial instruments were critical in this progress. Visible chart records replaced photographic methods so that the operator could monitor the spectrum during the long 30-min scan time (although the point-by-point recording of Figure 3 required a far longer time), and systems such as the "teflon slug" method were developed to measure and introduce a few milligrams of liquid and solid samples [6]. Unit resolution spectra were recorded over a 150-200-mass unit range, providing > 10 2 resolution increments of data in a spectrum.…”
