Using the Manual Injection Valve
An Alternative Way to Fill The Loop
An Alternative Way to Fill The Loop
When the sample loop is completely filled you can either inject the sample into the
loop or use the syringe to draw the sample through the loop.
1 Move valve to LOAD position.
2 Place vent tube from port 6 into sample vial.
3 Insert needle of syringe into needle port until needle touches stator face. Do not press
too hard.
4 Slowly draw sample into syringe.
5 Leave syringe in position and move valve to INJECT position.
6 Remove syringe.
If you use this method, always flush the loading passages (vent tube on port 6) after
each injection to prevent cross-contamination between injections. Remember — to
flush port 6 and the vent tube, the valve must be in the LOAD position.
