MANUAL LONG-TERM SHUTDOWN
Make sure your HPLC pump is running storage eluant through the analytical column (see Application section
for proper eluant) and then remove the column for storage. Replace the column with a union and the eluants
with Water and Methanol. Set the HPLC pump to 80% Water and 20% Methanol at 1.0 ml/min. This will prevent
backflow into the column during Flush procedure.
Create a Flush method as described in section 4.9 under the Advanced Settings tab of this manual. Set up a
Sequence with one run of a Flush method and load it into Pinnacle PCX software.
Select Enable function in the Control menu.
Select Instrument – Maintenance- Flush Instrument. Follow directions on the screen to complete this
procedure.
After Flush Instrument is completed select Disable function in the Control menu of the Pinnacle PCX software to
turn OFF heaters and pumps.
Allow the HPLC to pump at least 30 minutes to allow for the reactor to cool.
AUTOMATIC LONG-TERM SHUTDOWN
Create a Flush method as described in section 4.9 under the Advanced Settings tab of this manual. Set it up as
the last method of your Pinnacle PCX sequence.
Create a corresponding method for your HPLC to flush analytical column with the storage eluant (see
Application section for proper eluant) and set it up as a last method of your HPLC sequence.
After sequence is completed select Disable function in the Control menu of the Pinnacle PCX software to turn
OFF heaters and pumps.
Allow the HPLC to pump at least 30 minutes to allow for the reactor to cool.
STORAGE
If the Instrument will not be used for a period longer than 2 weeks, it must be put into Storage state. This
becomes necessary because as reagents age, the chances of precipitation in the heated reactor increases.
Perform Manual or Automatic Long-Term Shutdown as described above.
Remove the reagents and replace them with a solution of 80/20 Water/Methanol.
