Sampling System For Mass Spectrometer
Sampling System For Mass Spectrometer
US Patent:
4201913, May 6, 1980
Filed:
Oct 6, 1978
Appl. No.:
5/949295
Inventors:
William W. Bursack - Minneapolis MN
Erik T. Tromborg - Minneapolis MN
Erik T. Tromborg - Minneapolis MN
Assignee:
Honeywell Inc. - Minneapolis MN
International Classification:
B01D 5944, H01J 3934
US Classification:
250288
Abstract:
An apparatus for introducing a gaseous sample into a mass spectrometer is disclosed which includes a hollow antechamber or cavity disposed between the sample stream and the high vacuum enclosure. Orifice openings are provided in the antechamber which allow the antechamber to communicate both with the high vacuum enclosure and the sample stream. An electrically operated pulsed valve is used to admit a series of small volumes of sample by pulses of controlled duration and frequency such that the sample flow from the antechamber into the high vacuum enclosure can be made to resemble one of essentially constant flow.

US Patent:
3992626, Nov 16, 1976
Filed:
Apr 26, 1973
Appl. No.:
5/354707
Inventors:
William W. Bursack - Minneapolis MN
Assignee:
Honeywell Inc. - Minneapolis MN
International Classification:
B01D 5944
US Classification:
250288
Abstract:
A mass spectrometer, including a getter-ion pump, in which the sample to be studied is admitted to the spectrometer in pulses at spaced intervals, the rate of gas admission being so chosen, with respect to the pulse duration and interpulse interval, that the amount of gas admitted during each pulse does not exceed the capacity of the ion-getter pump to remove in the interval before the next pulse. The average gas density accordingly does not vary unduly, while the ion concentration during the pulses is appreciably greater than the average ion concentration, and the interior of the spectrometer is in substantially free communication with the gas to be analyzed during the pulses.
