2.3 Connection to a Modular IC System for Neutralization
793 IC Sample Prep Module/ 8.793.1003 Instructions for Use
11
Please note, that the suppressor of the 753 IC Suppressor Module is
not switched by the 766 Sample Processor program. The remote con-
nection 16 16 16 16 (suppressor/actuator) of the 753 IC Suppressor Module is
connected to the event line “fill” of the 733 valve B instead, using the
6.2128.180 cable. Thus the suppressor is switched when the fill position
is accessed by valve B.
2.3.2 Connection of the SP Module A
The following description implies the usage of the 2.733.0120 IC Sepa-
ration Center (two injectors).
The 1.793.0110 SP Module A must first be inserted in the 733 IC Sepa-
ration Center and connected to the 793 IC Sample Prep Module. Addi-
tionally, the suppressor block of the 753 Suppressor Module is inserted
and connected, which is described in detail in the corresponding
8.753.1001 Instructions for Use.
The connection of all parts should be done as described by the follow-
ing scheme:

A) Sample loop at valve B
is filled.
B) Sample is neutralized
by SP Module A;
Anions are preconcen-
trated via valve A..
C) Preconcentrated
anions are eluted to
the separation column.
