Analysis Settings
Developing your own method allows you to optimize the system for your particular
application. If, for example you want to run benzene, toluene and m-xylene (BTX)
as quickly as possible you can increase the pressure, increase the temperature and
decrease the analysis time.
When you make any changes to the analysis settings, the reference library will be
invalid. The retention times for library compounds become invalid when you change
any of the analysis parameters. The reference library is still available on the disk
supplied with the instrument. It will not be accessible from SiteChart unless you
load it from the disk again.
You may have to perform a few runs in order to optimize your method. Once you
have obtained well-separated peaks at the desired analysis time then you can store
the compounds in the library.
Analysis Time
Analysis time is the duration of the analysis. You must set the analysis time so that
all compounds of interest clear the column and pass into the detector. Refer to the
assay notes to determine the correct analysis time for your application.
To set the analysis time:
1. Select the Assay tab.
2. In the Method box, click Config .
The Configure dialog is displayed.
