d. Check the readback for flow sensor A. Then, depending on the flow rate, do one of
the following:
• If the flow rate is <100 nL/min, do the following:
i. Stop the Analytical Column Equilibration script.
ii. Disconnect the damaged solvent line from the mixing Tee's inlet for the
solvent A channel.
iii. Install a new solvent line between the mixing Tee's inlet for the solvent A
channel and the flow sensor's outlet.
For ordering information, see
iv. Reconnect the solvent lines, and rerun the system leak test (see
