1.1 Instrument description
1 Introduction
1.1 Instrument description
The 793 IC Sample Prep Module consists of a reactor block (SP
Module A) with its corresponding control unit; this contains an addi-
tional 2-channel peristaltic pump.
Inline sample pretreatment like neutralization or cation exchange for ion
chromatographic analyses can be carried out with the cation exchanger
built into the SP Module A. The SP Module A contains three cation ex-
change units which are in turn used for cation exchange, regenerated
with acid and rinsed with water. In order to perform each analysis under
comparable conditions a freshly regenerated cation exchange unit is
normally used. Switching is either carried out automatically by the IC
system or manually. Due to possible interference of sulfate with the IC
determination, perchloric acid is normally used for cation exchanger regeneration of the SP Module A instead of sulphuric acid.
At the control unit the SP Module A can either be switched to the next
position manually or by remote control via the remote interface. The
built-in peristaltic pump, which delivers the solutions required for operating the SP Module A, can also be switched on by remote control or
manually.
The 793 IC Sample Prep Module is particularly suitable for retrofitting a
modular anion IC system for inline sample pretreatment in a simple
manner. Two typical applications are described in detail in these instructions for use: Neutralization (e.g. exchange of Na
Cation Separation (e.g. exchange of heavy metals by H
the 793 IC Sample Prep Module can also be combined with all other
HPLC components currently on the market.
Although in principle the techniques of cation exchange by the 793 IC
Sample Prep Module and suppression by the 753 Suppressor Module
are comparable, the 793 IC Sample Prep Module is not suitable for
chemical suppression after ion chromatographic separation of anions.

1 Introduction
1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 793 IC Sample Prep Module is assured in the context of the specifications IEC 1010-1 (protection
class I, degree of protection IP20), the following points should be noted:
x Mains connection
Setting the mains voltage, checking the mains fuse and the mains
connection must be effected in accordance with the instructions in
section 2.2.
x Opening the 793 IC Sample Prep Module
When the 793 IC Sample Prep Module is connected to the power
supply the instrument must neither be opened nor should parts be
removed from it, otherwise there is a danger of coming into contact
with components which are live. Always disconnect the instrument
from all voltage sources before you open it and ensure that the mains
cable is disconnected from mains connection 19
19 !
1919
x Protection against static charges
Electronic components are sensitive to static charging and can be
destroyed by discharges. Before you touch any of the components
inside the 793 IC Sample Prep Module, you should earth yourself and
any tools you are using by touching an earthed object (e.g. housing of
the instrument or a radiator) to eliminate any static charges which
exist.
1.4.2 General precautionary rules
x Handling of solvents
Check all pump tubings and all input and output lines periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.
x Regular exchange of pump tubings
Pump tubings are consumable material and must be replaced from
time to time (see Section 4.2.4). Suitable measures must be taken so
that any leak which might occur in the pump tubing or connections
during unattended operation will cause no damage (placing the
instrument at the bottom, collection device for any liquid which may
leak out).

2.1 Setting up the instrument
2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The 793 IC Sample Prep Module is supplied together with the separately packed accessories in special packagings containing shockabsorbing foam linings designed to provide excellent protection. The
actual instrument is packed in an evacuated polyethylene bag to prevent the ingress of dust. Please store all these special packagings as
only they can assure damage-free transport of the instrument.
2.1.2 Check
After receipt, immediately check whether the shipment is complete and
has arrived without damage (compare with delivery note and list of
accessories in section 5.2). In the case of transport damage, see
instructions in section 5.4.1 "Warranty".
2.1.3 Location
Position the instruments in the laboratory at a location convenient for
operation, free from vibrations and protected against a corrosive
atmosphere and contamination by chemicals.
2.1.4 Arrangement of the instruments
The best position for the 793 IC Sample Prep Module is beside the Modular IC System (e.g. 733 IC Separation Center).
The 793 IC Sample Prep Module should always be placed at the
bottom of the instrument stack so that any leaks which may occur in
the pump tubing or connections cannot cause damage to the other
instruments by leakage of corrosive liquids (e.g.acid).

wrong mains fuse there is a danger of fire!
2.2.1 Setting the mains voltage
Before switching on the 793 IC Sample Preparation Module for the first
time, check that the mains voltage set on the instrument (see Fig. 2)
matches the local mains voltage. If this is not

Ensure that the instrument is never put into operation with fuses of
another type, otherwise there is danger of fire!
For checking or changing fuses, proceed as described in section 2.2.1.
2.2.3 Mains cable and mains connection
Mains cable
The instrument is supplied with one of three mains cables:
x 6.2122.020 with plug SEV 12 (Switzerland, })
x 6.2122.040 with plug CEE(7), VII (Germany, })
x 6.2133.070 with plug NEMA 5-15 (USA, })
which are three-cored and fitted with a plug with an earthing pin. If a different plug has to be fitted, the yellow/green lead (IEC standard) must
be connected to protective earth (protection class I).
Any break in the earthing inside or outside the instrument can make it
a hazard!

2 Installation
2.3 Connection to a Modular IC System for Neutralization
An important application for the 793 IC Sample Prep Module is neutralization of an alkaline sample for anion determination by IC with chemical
suppression. Strong bases (e.g. 30 % NaOH) should not be led unlimited to the SP Module A. To provide a sufficient capacity for exchanging
+
by H+ Ions, only a small fraction (e.g. 20 µL) is directed to the SP
Na
Module A using a sample loop. The analyte anions are preconcentrated
subsequently on a preconcentration column and finally eluted to the
separation column in counter flow by the eluent.
Therefore, such an IC system corresponds to the Modular IC System
6 (MIC 6: Anion system with chemical suppression, preconcentration
and matrix elimination) enhanced by the 793 IC Sample Prep Module.
If the sample doesn’t require matrix elimination and preconcentration, it
can be treated directly by the SP Module A. This could be an option for
samples containing only low amounts of the cations which have to be
eliminated. For this purpose, a system as described in section 2.4
should by used.
The following pages describe the electronic connections of this system
in combination with the 766 IC Sample Processor on the base of full
control by «IC Net 2.1».
2.3.1 Electrical connection
The 793 IC Sample Prep Module is connected to an IC system consisting of 732 IC Detector, 733 IC Separation Center (two injectors), 709 IC
Pump, 752 IC Pump Unit, 753 IC Suppressor Module and 762 IC Interface as shown in Fig. 5.

2.3 Connection to a Modular IC System for Neutralization
A
Please note, that the suppressor of the 753 IC Suppressor Module is
not switched by the 766 Sample Processor program. The remote connection 16
16 (suppressor/actuator) of the 753 IC Suppressor Module is
16 16
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 Separation Center (two injectors).
The 1.793.0110 SP Module A must first be inserted in the 733 IC Separation Center and connected to the 793 IC Sample Prep Module. Additionally, 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 following scheme:

is filled.
B) Sample is neutralized
