  • Publication number: 20210267477
    Abstract: A system for identifying and/or measuring a substance concentration in the exhaled breath of a patient (4), comprises a measurement apparatus (20) for performing an ion mobility spectrometry measurement of a sampling gas stream (A) obtained from the exhaled breath of the patient (4), the measurement apparatus (20) comprising a drift detector (22) and at least one gas circuit (23, 24) connected to the drift detector (22) for guiding an analytic gas stream (B), into which a sample of the sampling gas stream (A) is injectable, towards an inlet end (220) of the drift detector (22) and/or a drift gas stream (C) towards an outlet end (221) of the drift detector (22), wherein the at least one gas circuit (23, 24) comprises a molecular sieve filter (233, 241) comprising a filter material (26) for filtering the analytic gas stream (B) and/or the drift gas stream (C). Herein, the filter material (26) comprises the zeolite NaY.

  • Publication number: 20070069145
    Abstract: The invention relates to a procedure and a facility which can be used to quickly and reliably discover and identify dangerous goods, such as explosives, chemical warfare agents or narcotics in pieces of baggage. For this purpose, the pieces of baggage to be examined are radiated with fast neutrons. For assessment, a time-resolved gathering of the occurring thermal neutrons as well as deconvolution of their decay curves and registration of the induced gamma radiation due to inelastic scattering and capturing radiation are carried out.

  • Patent number: 6803567
    Abstract: An ion mobility spectrometer with a GC column and an internal circulation system is provided which can be used in trace gas analysis. Due to the special design of the gas circulation, the parameters: carrier gas velocity in the GC column, the flow rate of the gas to be analyzed and the flow rate of the drift gas can be varied extensively independently and without reaction. Additional pumps and gas splitters are arranged in the circulation system for this purpose.
