3.5 Rinsing/Priming the System
During a rinse cycle, approximately 5 mL of solvent is pumped through the
system. Run a rinse cycle at the following times:
•
After initial setup
•
After refilling the solvent reservoir
•
After changing solvents (rinse twice to remove all of the previous solvent)
•
When the solvent lines contain air
•
When acids, bases, salts, or buffers are used as extraction solvents, rinse the
system with deionized water at the end of operation.
•
After the ASE 150 has been shut down for more than one day (see
Section 3.9 )
To run a rinse cycle:
1. Rinse cells are similar to sample cells, but they are blue in color. Check that
the rinse cell size is matched to the sample cell size.
2. Install the rinse cell in the cell holder. Rinse cells are installed in the same way
as sample cells; for instructions, see Section 3.2.5 .
3. Close the cell door.
4. Open the collection vessel compartment door, toggle the needle switch (see
Figure 3-10 ) to the
UP
position, and install a new collection vessel (see
Section 3.1.6 ).
5. Toggle the needle switch to the
DOWN
position.
6. Close the door.
7. Press
RINSE
to begin the rinse cycle. The LED on the
RINSE
button turns on,
and will remain lighted while the rinse cycle is in progress.
