Scion Instruments

INSTALLATION OF COLUMNS, FLOW AND PRESSURE SETTINGS

Tuning of the analyzer is only necessary in case new columns are
installed or after flow or pressure settings have been changed
Make sure, the instrument is connected to the minimum gas supply
pressures as indicated in the pre-installation requirements (section 2 of this
manual).
For more detailed information concerning the configuration of the
instrument, refer to the drawing section (section 6 of this manual). The
factory drawing indicates which flow and pressure controllers are used. The
drawing also outlines the way the analyzer channel has been incorporated
into the gas chromatograph.
Regularly replace gas purification filters as well as eventual filters
mounted in the pneumatic compartment of the instrument.
Connect the columns according the flow schematics given in Section
6 and adjust the flows (if necessary) at an oven temperature of 50°C.
Check all connections for leakages.
It is advised to use an electronic leak detector, since 'Snoop' or
equivalent soap solutions contaminate the analytical flowpath
of your instrument. Take very good care not to create any dead
volume
