A mass spectroscope capable of recording the trend of many chemical species in rapid gas-phase reactions is described. The instrument represents a departure from analytical mass spectrometric practice by using a molecular streaming source, rapid electric scanning, an electron multiplier ion detector amplifier, and a cathode ray tube display. A 40 peak spectrum can be scanned in five milliseconds and recorded by a motion picture camera. A few results obtained with this instrument in the study of diethyl ether cool flames are given.
