Note
Mixed reverse phase and normal phase solvents may require
manual flushing of the pumping system between separations.
• If the CSVM was ordered with the instrument, it will
arrive installed in the ACCQPrep.
• If you decide to add this capability at a later time, this
can be easily accomplished in a manner of minutes
following the instructions included with the valve
upgrade (PN 68-5237-102).
Columns are mounted onto the CSVM in the same manner as a
system without the CSVM (Section 2.4.1). The CSVM comes with
additional column mounts and an assortment of precut tubing
and fittings to support the additional columns. When the
columns are connected, the inlet and outlet of the columns are
connected to the column select valve instead of directly to the
injection valve. The columns are identified on the CSVM as 1
through 4 and can be assigned a meaningful name in the
PeakTrak software (such as 20x150 Hi pH).
If you would like to flush the internal tubing of the ACCQPrep
between solvents (such as when changing from a low pH to a
high pH), one of the column positions (such as position 4) can be
connected with a length of tubing. For ease of use, the column
defined for the position could be called "Flush". When changing
from a low pH to a high pH solvent, a line can be placed into the
AutoSampler queue to use a method with neutral pH solvent to
flush the fluid lines. This assumes that the system has the
CSVM option installed.
ACCQPrep won't turn on using the front panel power
switch –
• Ensure power cord is connected.
• Verify that rear panel circuit breaker is in the "1"
position. (The breaker looks like a white rocker switch
on the rear panel near the cord inlet.) Switch breaker to
off and then back on to ensure the circuit breaker is
reset.
• Ensure the lab power connection has power.
Error: "Unable to communicate with pump controller
module" –
• Check the pump communication connector at the top,
left corner and the pump power connector at the top
right corner of the pump subassembly. Ensure the
connectors are oriented so that the locking tab is at the
top.
