• Connect nitrogen gas by means of the provided
hose. The corresponding joint contains a quick-
lock mechanism. The nitrogen gas connection
is located on the right hand side panel. The
required pressure range is 6 – 10 bar. This
pressure has to be set at the external pressure
reduction valve.
• Connect the other end of the nitrogen line
to a nitrogen tank by means of the provided
1/8” Swagelok brass nut and ferrule
(P/N 11055342).
• Connect the solvent reservoirs on the right hand
side panel. Make sure that the ferrule is pointed
towards the fitting to avoid leaking, and flush
with the end of the tubing.
NOTE
Close vacant ports with a blind fitting (P/N 035665) to avoid any unwanted contamination.
Never use technical grade solvent. It is strongly recommended to use p.a. quality or HPLC grade
solvents. To avoid contamination by the nitrogen use 5.0 quality for trace analysis and 4.5 for other
applications.
NOTICE
Risk of instrument damage by excess pressure within the instrument.
• Make sure that the maximum pressure of the nitrogen does not exceed 10 bar
NOTICE
