11. Align the sampling needle in the inject port (see Section 5.8
) and then
calibrate the inject port volume (see Section 5.9

the inject port and calibrating the inject port volume.
Do not cut the needle seal line to shorten it, and do not replace it with
a different line. The needle seal line is specially constructed and the
autosampler will not function correctly if this line is shortened.
