11.1 The Method Editor
The HAPSITE Method File provides for the total identification and qualitative
analysis of volatile compounds in the sample. The main components covered in
this section, which are used to build the HAPSITE Method File, are the Inlet
component, which is built on the Inlet page, the Acquisition component, which is
built on the Full Scan page, and the Calibration/Quantitation component, which is
built on the Search page.
When completed, this HAPSITE Method File can be downloaded to the HAPSITE
so that the HAPSITE can run in Portable Mode, without the need for an external
computer. This chapter will instruct how to build a method to quantify a VOC
(Volatile Organic Compound).
The Method file is employed at an incident site where the hazard has not been
identified. A HAPSITE Method File will allow a search from a default range of 45 to
300 AMU and generate a data file for analysis. The file will include many expected
(or target) compounds, for which the instrument can be calibrated, but may also
include unexpected compounds. The unexpected compounds are tentatively
identified by a NIST library search, for which quantitation can only be approximate.
Before being able to quantify a compound, one must develop a HAPSITE Method
File to specifically target suspected compounds. The information needed for each
component of the HAPSITE Method File is programmed on the following pages:
 The Description page, which specifies the type of Method being built.
 The Startup page, where all initial temperatures are set, and where the input
device is determined (i.e. Probe, Headspace or SituProbe).
 The Inlet page, which provides the Inlet component, defining the
temperatures, timing, and other gas chromatograph parameters as well as the
control parameters of the Headspace Sampler, if installed.
 The Tune page provides the Tune/Calibration component, which is essentially
the selection of a file that provides the expected response to the target
compounds and the internal standards. The Tune Report is also available on
the Tune page.
 The Full Scan component, which defines the mass range and other
parameters of the Mass Spectrometer operation, is defined on the Full Scan
page. For SIM collection, this component is configured on the SIM page.
