Measurements in the raw gas of a full scale municial waste incinerator using a wavelength resolved REMPI mass spectrometer

Autor: Reinhold Thanner, Matthias Nomayo, Roland Stützle, Horst-Henning Grotheer, Heinz Pokorny

A resonance enhanced multiphoton ionization (REMPI) mass spectrometer consisting of a tunable laser unit (Nd:YAG pump laser and OPO) and a reflectron mass spectrometer have been upgraded to cope with the difficult conditions such as vibrations, tempe

Continuous Monitoring of Ultratrace Products of Incomplete Combustion during Incineration with a Novel Mobile Jet-REMPI Device

Autor: Reinhold Thanner, H.H. Grotheer, H. Oser

Jet-REMPI is our modification of the well-known REMPI mass spectrometry. This modification allows for a significant sensitivity improvement over more conventional designs without loosing the high selectivity which is normally found with REMPI. The im

DLR-Jet REMPI - Ultrasensitive Monitor for Process Control in Thermal Processes

Autor: Horst-Henning Grotheer, Harald Oser, Reinhold Thanner

Process control requires sensitive and selective on-line monitors for species concentrations. This applies in particular if feeds of varying compositions are involved. Current REMPI (= Resonance Enhanced Multiphoton Ionization) mass spectrometers wou

Jet-REMPI for process control in incineration

Autor: Reinhold Thanner, Roland Walter, Ulf Richers, Albert Merz, Harald Oser, Horst-Henning Grotheer

Publikováno v: SPIE Proceedings.

The mobile Jet-REMPI apparatus is an optimized variant of the conventional REMPI mass spectrometry which is known for its selectivity and on-line capability. By shifting the ionization volume from the molecular regime of the sample beam as in convent

Low-noise ion source for the implementation of Jet-REMPI: novel on-line monitor for process control

Autor: Harald Oser, Reinhold Thanner, Horst-Henning Grotheer

Publikováno v: SPIE Proceedings.

Modern techniques for on-line process control require versatile monitoring mthods which combine high sensitivity with high selectivity. In this paper a novel REMPI-mass spectrometer is presented. In comparison to standard instruments, sensitivity is
