Installing the input of the separation column

There are 3 possibilities:

￭ Attaching the bottom end of the separation column directly to

the guard column.

￭ If the guard column is connected to the separation column using

a provided connection capillary, connect the bottom end of the

separation column to the guard column's output capillary using

the provided PEEK pressure screw (6.2744.070).

￭ If no guard column is used (not recommended), connect the col-

umn input capillary to the input of the separation column using a

short pressure screw (6.2744.070).

Rinsing the separation column

￭ Place a beaker under the separation column's outlet.

￭ Start manual control in MagIC Net and select the high-pressure

pump: Manual ▶ Manual control ▶ Pump

lary.

ration column using a PEEK pressure screw (6.2744.070).
