HAPSITE Smart Operating Manual
Internal Standard . . . . . . . . . . . . . . a mix of known concentrations of known
compounds which are installed in the
HAPSITE, mixed with calibration compounds
during calibration and with samples during
analysis to validate the response of the
HAPSITE to the target analytes.
Ion Energy. . . . . . . . . . . . . . . . . . . . These settings in the Tune program directly
affect the intensity of mass peaks. Ion
energies are commonly used to set the
relative mass intensities of the tuning ions.
Ion Volume . . . . . . . . . . . . . . . . . . . The specific space in the ionizer within which
ionization of the sample takes place.
Ion . . . . . . . . . . . . . . . . . . . . . . . . . . An atom or molecule which carries an electric
charge due to depletion or addition of one or
more electrons.
Ionizer . . . . . . . . . . . . . . . . . . . . . . . The assembly of parts in the mass
spectrometer into which the sample flows
and which projects a beam of mixed ions into
the mass filter.
I.S. Reference . . . . . . . . . . . . . . . . . This section of the Compound Library
identifies the target ion of the internal
standard which will be used for quantification
of the chosen compound.
kPa . . . . . . . . . . . . . . . . . . . . . . . . . . Kilo Pascal. Unit of pressure measurement
which is equivalent to approximately 0.145
PSI.
LCD . . . . . . . . . . . . . . . . . . . . . . . . . Liquid Crystal Display. This refers to the
display screen on the front panel of the
HAPSITE.
Lead In. . . . . . . . . . . . . . . . . . . . . . . The time which is allowed for the mass
spectrometer to stabilize before detecting a
mass during SIM analysis.
Library . . . . . . . . . . . . . . . . . . . . . . . A user compiled list of compounds, which
includes both analytes and internal
standards (if chosen). The Library keeps
information such as the name, target ion,
concentration, retention time, relative mass
intensities, and compound specific search
parameters (if selected).
LL . . . . . . . . . . . . . . . . . . . . . . . . . . . Left Limit.
