Outlet Tubing - Gilson 155 User Manual

Installation
Capillary
For the capillary flow cell the inlet and outlet
capillaries are interchangeable. Designate one of
the capillaries as the inlet and connect it to the
column outlet using the fitting from the accessory
package.

Outlet Tubing

The detector's Teflon outlet tubing can be directed
three different ways:
• to another type of detector where you can
monitor a second characteristic of your sample.
Use the appropriate coupler to make the
connection.
• to the inlet of your fraction collector if you want
to collect the column effluent. Use the appropriate
coupler to make the connection.
• to drain if you don't need to save the column
effluent.
Back pressure regulator
When using an HPLC flow cell, you may need
additional back pressure on the outlet tubing to
reduce bubble formation. If effluent is going to a
fraction collector or drain, connect the outlet tubing
to a back pressure regulator before directing the
effluent to the fraction collector or drain.
Analytical, microbore, and preparative
The detector accessory packages for analytical,
microbore, and preparative flow cells include the
back pressure regulator shown on the right. The
arrow on the back pressure regulator identifies the
direction of flow.
