6.8.1 Metrohm SDU features

A Metrohm SDU (Solvent Delivery Unit) system can be used for

high-pressure gradient mixture of one to four eluents. For each

eluent, a 709 IC Pump is used. Each 709 IC Pump must be con-

nected to the 762 IC Interface using a 6.2134.080 or 6.2134.090

cable. Examples for interconnections with the 709 IC Pump can

be found in the 762 Instructions for Use.

The outlet capillaries of the 709 IC Pumps must be connected to

a mixing chamber from where one inlet capillary leads to the in-

jection valve of the 733 IC Separation Center.

For detailed information about the 709 IC Pump see 709 Instruc-

tions for Use.
