Checking for Leaks
Several of the autosampler components have a limited life and will wear out
under normal use. Standard maintenance procedures require that you
periodically check these components for leaks.
Shut down and unplug the autosampler power cord.
1
Visually inspect the peristaltic pump tubing, rinse tubing, and sample probe for
leaks or signs of deterioration.
2
Carefully inspect the tip of the probe looking for cracks, chipping, or other
signs of deterioration. Inspect all tubing for signs of wear and obvious damage.
Inspect all fluid fittings for signs of wear or damage.
If you detect a leak or other damage to an autosampler component, you must
replace it. For more information, see the appropriate section in this chapter.
Replacing the Rotary Tray
Cleaning the ASX-112FR Autosampler rotary tray extends its life and makes
frequent replacement unnecessary. However, if the rotary tray needs to be
replaced, complete the following steps:
Shut down and unplug the autosampler power cord.
1
Remove the cover.
2
Remove all sample and standard vials and the sample rack.
3
Move the autosampler arm over the rinse position by gently pushing it.
4
Moving the autosampler arm ensures that the sample probe assembly will not
be damaged while you replace the rotary tray.
