Inspecting the Fluid Path (Tubing and Syringes)
WARNING
DO NOT attempt to adjust any connections while the autosampler is in
operation. Ensure that you wear appropriate protective gloves when
handling fluid lines that may contain harmful materials.
Air in the lines after priming can indicate a leak.
Check that all the tubing is clean and free of crimps. Look out for dents or scratches, liquid
on the outside of the tubing, air gaps, and any blockages or stationary pockets of liquid.
Tighten the connections between the flow cell and the injection station, and between the
injection station and the FCM. If you need to replace the tubing, refer to Installing the Flow
Cell / Injection Station Fluid Lines
on page 114. To replace all other tubing or components,
contact your PerkinElmer Service Representative.
Check for leaks around the syringe valves (Figure 69) and ensure that they are tight. If
required, tighten them by turning counter-clockwise. Ensure that the upper port (without
tubing) is sealed correctly.
