System Description and General Operation
Solvent Module
Figure 4 PL-GPC 220 Solvent Module
The top section of the solvent module is temperature controlled to 32 °C,
preventing solvents such as 1,2,4–trichlorobenzene and dimethyl sulfoxide
freezing should the laboratory temperature fall below 15 °C. The warm air
from the top solvent section is then circulated across the pump head and
degasser and ventilated from the rear of the unit.
A vapor sensor located at the rear of the bottom section of the solvent module
samples the air before it is ventilated from the unit.
The top section of the solvent module will accommodate one of the following
reservoirs:
• 2x 2L bottles (see Figure 4 on page 11)
• 1 x 13 L stainless steel tank (see Figure 5 on page 12).
In the case of this last option, the tank can be vacuum-filled with fresh
eluent and the waste is plumbed directly out through the back of the
module and piped to an external container.
