3.1.5 Filling the Cell
Precautions:
•
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 run.
To fill a cell:
1. Use the funnel provided in the ASE 150 Startup Kit to carefully load
the sample into the top of the sample cell. To accommodate different
sample cell sizes, three funnels (with different inner diameters) are
available (see
Figure 3-6 ).
2. ( Optional ) To reduce the amount of solvent used during the run, 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 of the top
cell end cap.
4. Screw the top cap onto the cell body. Hand-tighten the cap.
Figure 3-6. Sample Funnels
Always tighten the cell end caps by hand. Use of a wrench or other
tool can damage the cell, as well as the seals inside the cell end caps.
