Why does Waters Laboratory Equipment reproducibility fail to meet specifications?
- D
  dawn28Aug 4, 2025
  Several factors can cause reproducibility issues with Waters Laboratory Equipment. These include air in the flow path (perform an initial wash using the 2707 Console or control panel), a leaking syringe (check syringe mounting and gasket; replace if leaking at the bottom), a leaking syringe valve (inspect and replace if needed), a worn rotor seal (replace the seal and inspect the stator), dead volumes in tubing connections (redo connections with new ferrules and nuts), or a broken degasser (repair and confirm operation).

What to do if a blank gives a peak too high for the criteria in Waters Laboratory Equipment?
- C
  Casey ParkAug 22, 2025
  If a blank gives a peak that is too high, it might be due to a solubility problem. In this case, modify the sample or wash solution. Alternatively, the blank could be contaminated, so try using a new blank.

What to do if no injection occurs with Waters Laboratory Equipment?
- J
  Jeff ReevesNov 9, 2025
  If no injection occurs, it could be due to a blockage in the flow path. To resolve this: 1. Disconnect the needle from the valve. 2. Start a manual wash. 3. If solvent flows from the injection port, inspect the needle; if no solvent flows from the injection port, disconnect the buffer tubing from the injector valve. 4. Start a manual wash. 5. If solvent flows from the open end, inspect the rotor seal; if not, disconnect the buffer tubing from the syringe valve. 6. Start a manual wash. 7. If solvent flows from syringe valve, inspect the buffer tubing; if not, check for overtightened connections throughout the flow path and check the syringe valve. Another cause may be leakage in the injection valve. To resolve this: 1. Disconnect the needle tubing and buffer tubing. 2. Connect port 1 to an ...
