HAPSITE ER Operating Manual
Inlet State . . . . . . . . . . . . . . . . . . . . This refers to a specification of the state of
the valves in either the HAPSITE or 
HAPSITE with HSS. The states of the valves 
control sampling, analysis, clean-out of the 
HAPSITE and HSS. It can also be user 
specified.
Internal Standard . . . . . . . . . . . . . . A mix of known concentrations of known
compounds which are installed in the 
HAPSITE. They are 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.
