Insert the sample line into the sample injection chamber fitting. Push the

tubing from the top until it is slightly above the bottom of the chamber

viewing window. Finger-tighten the nut on top of the chamber so the

sample line is secure.

8 Check the fitting connections at both ends to make sure they are not

leaking.

Turn on the stream, load a tube of DI water, and make sure none of the

fittings are leaking. If needed, unload the tube, turn off the stream, and

tighten the fittings. After tightening, if leaking still occurs, replace the

ferrule.

9 Verify the length of the sample line.

The sample line should not bow or bend when a tube is loaded. If you need

to adjust the length, unscrew the nut on top of the sample injection

chamber, adjust the length, and tighten the nut again.

Changing the Secondary Sample Line

This section describes changing the secondary sample line (see Figure 6-9 on

page 204). There is a different fitting at each end of the tubing, so the procedure

is divided into two sections.

Pinch Valve End

The procedure to replace the secondary sample line at the pinch valve end is the

same as for the primary sample line, except the replacement line is a 7-inch

length. Refer to Assembling the Collet Fitting at the Pinch Valve on page 205.

Do not overtighten the nut and do not use tools. Over-tightening the nut

can kink or damage the tubing.

Make sure all fittings are securely tightened. If any fitting is loose, the

tubing could detach during high-pressure operation, exposing the

operator to potentially biohazardous sample spray.
