Ensuring System Wellness (IC Devices)
Calibrating the ICS-1000/1500/2000 or ICS-1100/1600/2100 Flow Rate

When to Calibrate:

Every 6 months

If the OQ/PQ flow rate accuracy and precision test fails

 

 

Items Needed:

Backpressure tubing to create 14  ± 1.4 MPa (2000  ± 200 psi); use 0.076-mm (0.003-in) ID yellow PEEK tubing (P/N 049715)

Deionized water

Tared beaker

 

 Note:

Do not open a System Wellness Control Panel if the name includes "Service.pan." These Wellness panels are reserved for use by Dionex Service Representatives.

  1. Open the System Wellness Control Panel for the ICS-1000/1500/2000 or ICS-1100/1600/2100 (see  Opening a Wellness Control Panel).

  2. Locate the Pump Flow Rate Calibration controls. If desired, click Instructions for an overview of the calibration procedure.

  3. Click Reset Cal to reset the flow rate calibration value.

  4. Click 1.00 ml/min to set the pump flow rate.

  5. Allow the Current Pump Pressure reading to stabilize at 14 ± 1.4 MPa (2000  ± 200 psi) for 20 minutes.

  6. Click 5.00 min to start the timer and immediately start pumping deionized water at 1.00 ml/min.

  7. Collect water into a tared beaker for exactly 5 minutes.

  8. Enter the weight of the deionized water (in grams) in the Enter new Flow Rate Cal field.

  9. Click Calibrate to begin the calibration. When the calibration is complete, Chromeleon will download the new calibration value to the ICS-1000/1500/2000 or ICS-1100/1600/2100 and will store it as the current calibration value.

  10. Click Log to record the new calibration value in the Audit Trail. Chromeleon will automatically update the Current Calibration Date and Last Calibration Date fields.

  11. Wait at least 15 minutes, and then recheck the flow rate to verify that the calibration was successful.
