Maintenance and Robustness
-
Plug in replaceable DEP probe filaments (expected life
> 500 samples
-
Easily replaceable probe shaft seals (expected life
> 500 injections)
-
Sequence stops automatically if leaks, broken filaments or
other problems occur.
-
Vacuum gauge in isolation valve prevents insertion of
probe into source if seals are leaking.
-
Automatic repositioning of probe without vacuum leaks if
a power outage occurs when the probe is in the MS
vacuum
T
he SIS AutoProbe integrates a CTC liquid autosampler
with an automated Direct Exposure Probe (DEP) for the
automated and unattended injection of dissolved or sus-
pended samples directly into the Thermo TRACE DSQ
TM
or Polaris
Q
TM
MS source for direct MS analysis. Using this technique, samples
can be analyzed in about three minutes without any chromato-
graphic separation. The AutoProbe is fully integrated with the
Thermo XcaliburTM software, including system setup, methods
setup, system operation and data storage.
The DEP (or DCI) technique is a quick technique for the analy-
sis of samples that are not volatile enough to be introduced into the
mass spectrometer via a GC and therefore must be directly intro-
duced into the mass spectrometer source. The DEP technique is
normally used for single component samples since minimal sepa-
ration of samples is possible with this technique and samples with
two or more components are difficult to interpret. Alternatively DEP
sample analysis is performed utilizing CI (Chemical Ionization)
mass spectrometer techniques, which produce less fragmentation
and increase abundance of a molecular ion. Due to the increased
abundance of a molecular ion and reduced fragmentation in the CI
technique, it is possible to analyze and interpret mixtures of two or
more compounds in a sample.
