2-22 Installing the System
• For flow rates greater than ~10 mL/min and for large-scale operation,
connect the column outlet to the sample side of the detector cell with
0.040-inch ID tubing.
The table below shows tubing sizes for the various flow cells used in Waters
UV detectors.
Recycle and solvent inlet lines
The Startup Kit contains precut and prefitted lengths of PTFE tubing. These
are solvent recycling and solvent inlet lines, and their respective sizes are
0.040-inch ID and 0.019-inch ID.
Fluid pathways
Refer to the following illustrations when plumbing your Prep system.
The figure below shows tubing sizes for the standard PrepLC system’s fluid
pathways. This system is used for both small-scale and large-scale injections.
