HAPSITE Smart Plus Operating Manual
SituProbe . . . . . . . . . . . . . . . . . . . . The SituProbe Purge and Trap System is a
sampling accessory for the HAPSITE. It is
used for in-situ testing of volatile organic
compounds (VOCs) in water. Used in
combination with the HAPSITE, the
SituProbe accessory performs water
analyses for qualitative and quantitative
results in the field. The SituProbe can be
configured for both unattended and
continuous sampling as well as
user-initiated, manual sampling.
SM . . . . . . . . . . . . . . . . . . . . . . . . . . Service Module
Spectrum Grab . . . . . . . . . . . . . . . . This action is performed in the Run Method
program to store information about a
compound, including name, retention time,
and relative mass intensities for the 10
largest mass peaks. This information, when
grabbed, is stored in a grabfile.
Target Ion . . . . . . . . . . . . . . . . . . . . The specific ion mass which will be used for
quantification or primary identification of a
compound in the Library (also referred to as
Compound Library).
Temperature Programmable . . . . . Software controlled temperature
programming that allows the user to reach
temperatures from ambient to 225 °C in a
controlled ramp.
Threshold . . . . . . . . . . . . . . . . . . . . A measure of the amplitude of the
background noise of the mass spectrometer.
This is determined using the Noise Check
feature in the Tune program.
TIC . . . . . . . . . . . . . . . . . . . . . . . . . . Total Ion Chromatogram. A presentation of
the flow from the GC as measured by the
mass spectrometer, adding up the signals
from all the masses programmed and
presented as a function of time.
TMP . . . . . . . . . . . . . . . . . . . . . . . . . Turbo Molecular Pump
Torr . . . . . . . . . . . . . . . . . . . . . . . . . Unit of sub-atmospheric pressure.
