Connections
The following connections must be made to use your LWCC:
 Plumbing (Liquid Port) Connections
 Fiber Connections
Plumbing Connections
On the front panel, there are two plumbing feed-through (liquid) ports labeled SAMPLE IN and
SAMPLE OUT. It does not matter which one is used for the plumbing input or the plumbing output.
However, if an inline filter is to be installed, connect it on the input side of the liquid flow path. For
experimental consistency, once you have assigned which fitting will be the plumbing input and which one
will be the plumbing output, try not to switch the plumbing configuration. Install the luer-fitted
connectors to the ports. These fittings can be removed if the LWCC is to be connected to a fluid injection
analysis system or a liquid chromatography column.
Luer fittings may be replaced with other 1/16 inch (1.64 mm) OD tubing. Loosen the small nut at the base
of the luer fitting, remove the fitting, insert new tubing and tighten the nut. If a Sample Injector Kit is to
be used, it will take the place of the SAMPLE IN connector.
The tubing goes over the plumbing fittings, which are standard ¼-28 threads. The tubing should fit snugly
over the fittings and be free of leaks.
► Procedure
1. Attach one end of the tubing to your pump. The pump used must not pump the solution so fast
that the fluid pressure exceeds 45 PSI.
Note
Remember to always turn off the pump in-between taking a reference and taking sample
measurements.
2. Make sure you have a proper waste receptacle for the other end of the tubing.
