Connecting the eluent bottle

The eluent supply line from the storage bottle to the high-pressure

pump is connected as follows (see Figure 13):

eluents should be used!

The 6.1608.070 Eluent bottle (2 L) supplied is

not suitable for vacu-

um degassing. Use a pressure-resistant container for this.

Care must be taken that the

eluent used is freely miscible with any

solvent remaining in the pump head (the pump head leaves the fac-
