• Check each configured column's dimensions against the
actual column dimensions. (See "Configurable Items to
Always Keep Current".)
• Check the autosampler injection volume.

is marked at half- height on the barrel, not at the top of
the barrel, enter twice the labeled volume when
configuring the syringe size.
