1100 Series Nano Pump Service Manual 87
Troubleshooting and Test Functions 2
Running the Test
1 Prepare the restriction capillary (G2226-67300)
2 Slide the PEEK sleeve over the fused silica capillary.
3 Slide the SST fitting over the PEEK sleeve.
4 Slide the front and back ferrule over the PEEK sleeve.
5 Carefully press the capillary into an adjustment union and tight the fitting
moderately with the 4 mm wrench (8710-1534) and the torque adapter
(G1315-45003) to fix the ferrule.
6 Select the ChemStation’s Diagnosis screen; from the nano pump tests
selection box, select “Flow Sensor Accuracy Calibration Test”.
7 Start the test and follow the online instructions
NOTE
Make absolutely sure that all parts of the flow path that are included in the test are very
thoroughly flushed with WATER before starting to pressurize the system! Any trace of other
solvents or the smallest air bubble inside the flow path will definitely cause the test to fail.
NOTE
It is absolutely necessary that the pump is tight. We recommend to run the Micro Mode
Pressure Test to verify the tightness of the pump
quartz capillary
PEEK sleeve
SST fitting
front and back
ferrule
To reach right values for the flow sensor accuracy calibration the restriction capillary
G2226-67300 must not be damaged or blocked.
