CAUTION: Bypassing the solid load cartridge too soon during
the purification run may leave desired compounds on the solid
load cartridge. After removing the cartridge from the fluid
path, these compounds cannot be purified.
If you need to use this feature, perform the following to ensure
that you do not leave desired compounds on the cartridge:
1. Run a TLC plate prior to starting the run. Measure the Rf
(retention factor) of the slowest eluting compound of
interest. (The Rf should be between 0.2 and 0.8 — the same
range used by the G
RADIENT OPTIMIZER [4.3.3]). Note the
Percent B solvent used to run the TLC plate. If a compound
displays tailing peaks as streaks on TLC, the Rf used
corresponds to the bottom of the streak.
2.Load the Sample in the Solid Load Cartridge and note the
cartridge size. Refer to list below to determine the cartridge
volume. If the cartridge is partially filled with silica, use
the cartridge volume as if the cartridge were completely
filled with silica.
• 5 gram cartridge = 10 mL volume
• 25 gram cartridge = 45 mL volume
• 65 gram cartridge = 110 mL volume
3.Run the sample and observe the flow rate from the Status
Bar in the upper right corner of the main window. As long
as the system is delivering the programmed flow rate,
there is no need to bypass the cartridge.
4.If the flow rate is slower than that programmed, note the
slowest displayed flow rate. Use the equation below to
determine if the cartridge can be bypassed.
T = Cartridge Volume / (Rf * Flow Rate)
Where T is the time in minutes to wait after the system
reaches the %B solvent used to run the TLC plate; Rf is
the retention factor measured in step 1; Cartridge
Volume is the volume in mL from step 2; and Flow Rate
is the current flow rate in mL/min.
5.Observe the current %B concentration in the status bar.
Once the system reaches the %B percentage used for the
