Outlet Tubing Connection
1. Put the fitting(s) supplied with the flow cell on one end of the other piece of the cut tubing.
Use only nuts and ferrules made of PEEK or KEL-F.
●
For 1/16" flow cells, put a PEEK one-piece nut on one end of the tubing.
●
For 1/8" flow cells, put a KEL-F ferrule 1/8” and a PEEK nut 1/8" on one end of the tubing.
The ferrule tip should point to the nut.
2. connect the tubing to the upper flow cell outlet. Finger tighten the fitting.
3. The other end of the tubing can be connected to:
●
a back pressure regulator
● the inlet of the fraction collector in order to collect the column effluent.
Use an appropriate coupler to make the connection. These fittings are not supplied.
● a waste container if the column effluent does not need to be saved.
NOTICE
After making all tubing connections, turn on the mobile phase pump and check all connections
for leaks. Control potential leaking not only after detector installation, but also during
operation.
NOTE
Side and top slots on the detector front panel are designed to accommodate inlet and outlet tubing.
The 1/8" OD FEP tubing is fitted by pressing the tubing into the slot. The 1/16" OD tubing can be
fitted using a short piece of FEP tubing with outer diameter 1/8" and inner diameter 1/6", threaded
on the 1/16" tubing. Tubing threaded this way cannot be pressed in and it is fitted by inserting from
the side into the slot.
