2. Clean the lower container:
a. Rinse the lower container with a small amount of electrolyte, then replace the
upper container.
b. Pour electrolyte into the upper container until it is approximately one-half full;
allow the electrolyte to filter through to the lower container.
c. Remove the upper container.
d. Swish the electrolyte around in the lower container, then discard the electrolyte.
e. Replace the upper container.
f. Repeat steps b through e two more times.
3. Fill the upper container with electrolyte; allow it to filter through into the lower
container.
4. Remove the upper container, then pour the electrolyte into the supply bottle.
5. Repeat steps 3 and 4 until the supply bottle is filled.
Be sure to read about the ElectroPrep in the next section. The ElectroPrep automates the
filtering process, providing a continuous supply of electrolyte.
ElectroPrep
The ElectroPrep is designed to recirculate electrolyte through a filter cartridge that retains
particles greater than 0.1- to 0.2-micrometers in diameter. The electrolyte is contained in a
reservoir, providing a supply of clean electrolyte at all times.
For electrolytes in which sample particles readily disperse (e.g., alumina in saline water)
without having to add a dispersing agent, the waste liquid can simply be poured back into
the reservoir and used again and again. In typical usage under this circumstance, one prep-
aration of electrolyte will last several months before the filter cartridge has to be replaced.
This is also true with saturated electrolytes.
Waste liquid cannot be recycled when the sample material requires a special dispersing
agent because placing it back into the electrolyte would change the electrolyte
composition. The ElectroPrep is still useful in these situations by affording a ready source
of clean electrolyte to fill instrument sample beakers and supply containers. The
ElectroPrep can be employed with either aqueous or organic electrolytes by selecting the
appropriate cartridge. Refer to Ordering Information, page
ordering the ElectroPrep, or contact your local sales representative.
