Abstract: The invention relates to a gas inlet for producing a directional and cooled gas jet in an ion source or an ultraviolet fluorescence detection cell. The aim of the invention is to provide a simple means for modifying the gas inlet in such a manner that it facilitates an effective cooling of a continuous gas jet at a relatively low inlet volume flow. To this end, a capillary is used that leads in a gas-tight manner from outside into the evacuated interior of the ion source or the ultraviolet fluorescence detection cell. The end of the capillary that is located in the vacuum is provided with a nozzle for adiabatically cooling the gas. The diameter inside the nozzle opening is not more than 40 % of the diameter inside the capillary.

Abstract: The aim of the invention is to configure the gas inlet for an ion source in such a way that the point of expansion of the gas stream can be fed directly into the ion source of a mass spectrometer. To this end the invention provides for a capillary (1) for supplying a sample gas, a guiding tube which surrounds the capillary and contains a carrier gas, where the capillary opens into the guiding tube and the open end of said guiding tube ends in the ion source, a pulsed valve for supplying carrier gas to the guiding tube and a housing for holding the capillary, guiding tube and valve in a gas-tight manner, whereby the guiding tube protrudes from the housing.

Abstract: In a method for producing a directed gas jet wherein a guided sample gas beam is generated and an auxiliary gas beam is generated and directed and guided in the same direction as, but separated from, the sample gas beam, a pulsed carrier gas stream is generated and combined with the sample gas beam such that the sample gas beam is separated into spaced pulses which are embedded between the axially spaced pulses of the carrier gas beam and the carrier gas beam with the sample gas beam embedded therein is combined with the auxiliary gas beam such that the carrier and sample gas beam is radially enveloped by the auxiliary gas beam to from the directed gas jet of a carrier and sample gas pulses enveloped in the auxiliary gas beam.

Abstract: The invention relates to a method and a device for detecting compounds in a gas stream, enabling a plurality of compounds in the analysis gas to be characterised almost simultaneously. The gas stream containing the compounds is guided into the ionisation chamber of a mass spectrometer and exposed to radiation with a UV laser pulse. The resulting ions are detected in the mass spectrometer. The gas stream is exposed to said radiation with said UV laser pulses at regular or irregular intervals by alternate exposure to a vacuum ultraviolet (VUV) laser pulse in the ionisation chamber, the resulting ions being detected in the mass spectrometer.
