c. Agitate the solvent for a moment to allow the sample to
adsorb to the silica.
d. Remove the solvent with a suitable method, such as
rotary evaporation. Alternatively, you can dry the
prepared cartridge after step 5 by drawing the solvent
out using a vacuum or using the Torrent’s air purge.
3. Load the media and sample mixture into the cartridge. Tap
the cartridge on the benchtop to settle the mixture.
4. Place a frit on the top of the cartridge. Force the frit down
against the mixture using the plastic plunger.
5. Wipe away any residual powder inside the neck and top
rim of the cartridge.
Note
You can remove solvent from a prepared cartridge by attaching the
cartridge cap and manually purging (TOOLS>MANUAL CONTROL)
the cartridge with air.
Note
Empty solid sample cartridges also allow a variety of adsorbents,
such as diatomaceous earth, boiling chips, cotton balls, or paper
wipes. Even with alternative adsorbents, always use top and
bottom frits to prevent fluid path problems.
After you have prepared the pre-filled or empty cartridge,
place the solid sample cartridge on the system:
