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.
