he AutoProbe integrates a CTC liquid autosampler with
an automated Direct Exposure Probe (DEP) for the auto-
mated and unattended injection of dissolved or suspend-
ed samples directly into the Thermo DSQ, DSQ II, Polaris Q &
GCQ MS source for direct MS analysis. Using this technique, sam-
ples can be analyzed in about three minutes without any chro-
matographic 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 used for the analysis of samples
that are not volatile enough to be introduced into the mass spec-
trometer via a GC and therefore must be directly introduced into the
mass spectrometer source. The DEP technique is normally used
for single component samples since minimal separation of samples
is possible with this technique and samples with two or more com-
ponents are difficult to interpret. Alternatively DEP sample analysis
is performed utilizing CI (Chemical Ionization) mass spectrometer
techniques, which produce less fragmentation in the mass spec-
trometer. 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.
