2.3 PLUMBING CONNECTIONS TO THE DUOFLOW SYSTEM

The QuadTec has a PEEK flow cell that must be installed by the user. The detector fittings which have been
provided are standard HPLC 10-32 fingertight fittings. The BioLogic system uses 1/4-28 fittings.

To plumb the QuadTec to the BioLogic DuoFlow system:

Plumb the detector after the column and before the conductivity monitor with the orange or green
PEEK tubing provided with the DuoFlow. The tubing length between the column and the detector
should be as short as possible.

The flow is from the left to the right side of the instrument as shown in the picture below.
