HAPSITE ER Operating Manual
Full Method . . . . . . . . . . . . . . . . . . . Full method allows the user to specify a
range of masses to scan during analysis.
This is used when analyzing for several
compounds (typical analysis) or for analysis
of unknowns for tentative identification.
GC . . . . . . . . . . . . . . . . . . . . . . . . . . Gas Chromatograph.
Global Search Parameters . . . . . . This specifies the various parameters which
will be used to identify compounds which
have been included in the Library. These
parameters are used unless a separate set of
parameters is specified in the compound
entry of the Library and set at a higher
precedence level.
GUI. . . . . . . . . . . . . . . . . . . . . . . . . . Graphical User Interface.
Hand Control Unit . . . . . . . . . . . . . The inlet probe of the HAPSITE which
comprises a heated line and a hand piece
with a display and (4) control keys.
HAPSITE . . . . . . . . . . . . . . . . . . . . . Analytical Module acronym that stands for
Hazardous Air Pollutants on Site.
Headspace . . . . . . . . . . . . . . . . . . . The gaseous volume above a solid or liquid
sample in a closed vial, from which a
gaseous sample is taken for analysis.
Heated Line. . . . . . . . . . . . . . . . . . . The inlet line to the HAPSITE, comprising a
PEEK tube with a heating jacket,
temperature sensors and protective sheath.
HSS . . . . . . . . . . . . . . . . . . . . . . . . . Headspace Sampling System. This includes
components which, when used in
conjunction with the HAPSITE, allows the
user to quantify and qualify volatile
compounds in liquid and solid matrices.
Initialization . . . . . . . . . . . . . . . . . . The act of sending target temperature and
pressure settings to the HAPSITE or
HAPSITE and HSS, then allowing the
instruments to achieve these settings.
Injection . . . . . . . . . . . . . . . . . . . . . The application of a discrete amount of gas
and/or vapor at the entrance of the gas
chromatograph column.
