3.1.5 Filling the Cell
NOTE When filling the cell with sample, keep the threads
on the cell body and end cap as clean as possible to
prevent thread fouling and extend the life of the cell.
Also make sure that the ends of the cell body and the
seals in the end caps are clean; if debris remains
here, it will damage the cell body and/or allow leaks
during the extraction.
1. Carefully load the sample into the top of the extraction cell, using the
funnel (P/N 056699) provided in the ASE 100 Ship Kit (P/N 059397).
2. (Optional) To reduce the amount of solvent used during the
extraction, fill any void volume in the cell with an inert material such
as Ottawa sand (Fisher S23-2).
3. Using a soft brush or cloth, wipe all debris off the threads.
4. Screw the top cap onto the cell body. Hand-tighten the cap.
5. Check the ends of each end cap to verify that the O-rings are in place
and are in good condition (see Figure 3-2). If an O-ring is discolored
or has a hole size of less than 0.5 mm, replace it:
a. Use a small flathead screwdriver (P/N 046985) to remove the old
O-ring from the cell cap.
b. Place a new O-ring over the opening in the end of the cell cap and
press it into place, using the O-ring insertion tool (P/N 049660).
Always tighten the cell caps by hand. Use of a wrench or other
tool can damage the cell, as well as the seals inside the cell
caps.
