HAPSITE Smart Operating Manual
 if the instrument is to operate without the external computer, the appropriate
files must be downloaded to the HAPSITE,
 the instrument must be tuned. (see Chapter 7, Tune ),

the instrument must be calibrated to the target compounds. (See Chapter
12, Target Compound Methods .)
11.2.2 SIM Method
The SIM GC/MS method is the full speciation and quantitation of only specific (or
target) compounds expected to be in the sample.
This type of analysis should be used where the highest sensitivity (lowest minimum
detectable concentration) is required, and where the compounds to be measured
are known. The SIM GC/MS method might include one or many specific
compounds for which the instrument will be calibrated.
This work may be carried out with the HAPSITE installed on the Service Module or
separate from the Service Module; with the use of the laptop or without the laptop;
and with or without a HSS, SituProbe, or sample conditioning probe. Regardless of
the configuration, certain method elements must be defined and set-up procedures
must be carried out. The method elements are:
 If the HAPSITE is to operate separate from the Service Module, the HAPSITE
must have a NEG pump installed and activated. Refer to
section 2.7, Service
Module, on page 2-18 for additional information on the Service Module.
 The quantitation sequence method must be defined. This includes the
definition of:

the Data file (where the data will be stored),
 the Selected Ion Method parameters (which defines the masses to be
monitored and the elution times expected, as well as other parameters of
the mass spectrometer operation),
 the Library Search parameters (which designates which library file to
access, global GCMS peak designation/integration parameters, and
various reporting options),
 the Inlet method file (which defines the temperatures, timing, and other gas
chromatograph and head space parameters),
 the Tune/calibration file (which provides the expected response to the
target compounds and the internal standards),
 the Peak Plot file (which defines the handling and presentation of the data
from the analysis),
 the Setup file (which defines the parameters for the standby state of the
HAPSITE),
