Additional Information
A leak error may be caused by the Aligent 1200 sampler. In each sampler
injection sequence, step# 2 ejects the mobile phase stored in the metering
head during the previous injection. This mobile phase is ejected through the
short plastic tube connected to port# 4 of the sampler switching valve. The
output of port# 4 is integrated into the sampler's contingency leak drain
system, which eventually terminates in the leak pan of the bottom module of
the stack - the detector. With normal injection volumes and run times, the
output of port# 4 is small, and evaporates right in the sampler leak pan.
However, the output of port# 4 is significant, and a substantial volume of
ejected mobile phase reaches the detector leak pan.
There are two possible fixes. Select the one which is most convenient.
1 The waste drain plumbing orientation as shown in the figure below,
eliminates the possibility of any leak drainage from above reaching the
detector leak pan. The leak drain for the detector can be connected to the
detector's leak drain fitting, and taken to waste separately.
