Option Function
1 Syringe Size Use this option to set the syringe size.
Select option 1, Syringe Size. Select the syringe size that corresponds with the
Kloehn syringes loaded into the syringe pump. The Set Syringe Pump Parameters
screen displays.
2 Plunger Speed Use this option to configure the syringe pump plunger to operate at a specific speed.
Select option 2, Plunger Speed. Enter a plunger speed between 100 and 1500 motor
steps per second (sps) and press ENTER. The recommended value is 500. The Set
Syringe Pump Parameters screen displays.
3 Prime Loss Volume Use this option to configure the prime loss volume. Prime loss volume compensates
for the volume of medium used to fill the tubing between the sampling cannulas and
sampling valves during the priming cycle. When sampling, an amount of sample
equal to the prime loss volume flows past the valves in the 8000 before the valves
open to collect sample. The program also restricts this volume to be less than or
equal to the syringe size volume.
Select option 3, Prime Loss Volume. Enter a prime loss volume based on the sample
tubing length, inner diameter, and system dead volumes and press ENTER. The Set
Syringe Pump Parameters screen displays.
If the tubing length between the sampling cannulas and sampling valves is changed,
adjust the prime loss volume accordingly.
