…mass spectrometry can
also be performed using VUV lamps, for example, deuterium
lamps, as the photon source. Their power density, however, is
weak in the spectral range in question. This excludes MS with
conventional VUV-lamp ionization from applications considering
fast on…

…substantial part of the time-of-flight broadening, however, is
due the temporal profile of the VUV radiation pulses. After
switching off the lamp because of inactivation of the electron beam,
the VUV emission intensity decays with a half-life time in the range
of several microseconds, depending…

…generation of the VUV light. In general, the vacuum ultraviolet
(VUV) light sources for SPI-MS are based either on lasers
(e.g., 118-nm radiation generated by frequency-tripling
of the third harmonic of a Nd:YAG laser) or on conventional VUV lamps, such as deuterium lamps. Although the

…) Coupling of the Excimer VUV Lamp and the TOF Mass
Spectrometer. In this work, a previously built TOFMS system,
which was designed for laser ionization methods, was coupled to
a laboratory prototype of an electron-beam-pumped rare gas
excimer VUV lamp. A special flange was designed…

…allowed to vary all trigger pulses to vary for conveniently optimizing the triggering scheme. Figure 5 shows the timedependence of VUV light output (trace A) as detected with a VUV/
XUV detector (IRD Inc., type AXUV-20), the trigger pulse for the
TOFMS extraction HV pulse (trace B), and the TOFMS…

…, for
example, in exhaust gases (Figures 7 and 8).
Thus, already in its present form SPI-TOFMS with an electronpumped rare gas excimer VUV lamp as light source might be an
interesting alternative or supplement to other on-line mass
spectrometric approaches, such as the laser based…
