3.1.4 Installing the Cell Filter
A disposable filter must be installed in the bottom end of the extraction
cell before sample is loaded. The filter prevents blockage of the stainless
steel frit in the bottom cap.
There are two types of cell filters:
_
Cellulose filters (P/N 056780, pkg. 100) are appropriate for most
extraction methods that use organic solvents. The ASE 100 Ship Kit
(P/N 059397) includes a package of cellulose filters.
_
Glass-fiber filters (P/N 056781, pkg. 100) are recommended for
aqueous extractions, where cellulose may provide inadequate
filtration or may interfere with the analytical technique.
1. Screw a cell cap onto the bottom of the cell body. (There is a groove
around the top of the cell body, but no groove around the bottom.)
Hand-tighten the cap.
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
caps.
Always tighten the bottom cell cap onto the cell before
installing the cell filter. If you install the filter first, the cap will
not seal properly and will allow leaks.
