Safety Features in the Pinnacle PCX
The Pinnacle PCX system has features
designed into the instrument and operation
that will prevent reagent back-flow onto the
column and bursting of reactor tubing due to
a blockage.
Post-column reagent can immediately damage
the analytical column if the reagent flow is
diverted in the wrong direction by a lack of
HPLC flow.
This is prevented by:
1) In-line Check Valve
A one-way check valve placed
before the column prevents the
flow of liquid in the direction of
the column.
2) Over-pressure Relief Valve
In the rare event there is a blockage in the post-column system, an integrated 500 psi over-pressure relief valve
will open and divert the liquid into the drip tray. This will prevent a bursting of tubing or fittings. By relieving
the pressure, this will give you the opportunity to correct the blockage rather than having to replace the heated
reactor.
