3-16 Installing Options and Accessories
Requirements:
• You connect the eluent supply tubing from the eluent reservoirs to the
degasser’s pump A and pump B (In) inlet fittings, instead of directly to
the inlet connectors on the pump manifolds (see page 2-11 ).
• You connect the pump inlet tubing between the degasser’s pump A and
pump B (Out) outlet and the pump inlet connectors on the corresponding
pump manifolds (see page 2-12 ).
• If you are installing the degasser on a 1515 isocratic pump, you use only
one degasser vacuum chamber (A). In this case, fill the degasser’s
unused vacuum chamber (B) with eluent, and use pin plugs to cap the
unused chamber’s inlet and outlet fittings to prevent leaks.
Tip:
To minimize degasser equilibration time when using only one pump, fill
the degas tubing in the unused vacuum chamber with a fluid such as water or
eluent. Install caps on the chamber’s inlet and outlet fittings to prevent leaks.
Installing the degasser vent line
Besides removing dissolved gases from the eluents, the degasser can vaporize
some eluent components. The vapors can then condense, forming droplets in
the exhaust system. The degasser exhausts these gases and droplets through
a vent line that exits the instrument at the rear panel, as shown in the figure,
below.
Warning:
To avoid exposure to eluent vapors, connect the outlet vent on
the pump’s rear panel to a suitable fume hood. Consult your local
building and health codes for specific requirements regarding the
venting of eluent vapors.
