766 IC Sample Processor
1 Introduction
1.1 Instrument description
The 766 IC Sample Processor can be used for automating ion chromatographic determinations, especially in combination with the
Metrohm IC system instruments. The 127 sample tubes with a volume
of up to 11 mL are arranged on the sample rack in three rows, which
guarantees easy access and unrestricted programming. Two additional
rinsing positions allow sample introduction free from crosscontamination even with widely varying sample matrices. If the 766 IC
Sample Processor is used together with the 732 IC Detector and the
733 IC Separation Center, various injections are possible from a single
sample tube, depending on the sample size. Sample tubes made of
polypropylene are standard. To protect the samples from external contamination, the tubes can be hermetically sealed.
1.1 Instrument description
Sample introduction from the 766 IC Sample Processor is achieved by
means of its integrated peristaltic pump. The sample is conveyed by
the pump through the capillary into the sample loop of the injector located within the 733 IC Separation Center. A steel needle for sealed or
a PEEK needle for open sample tubes can be used alternatively. Owing
to the relatively large volume of the sample tubes the 766 IC Sample
Processor can also be used for applications with enrichment columns,
dialysis (with the 754 Dialysis Unit) or simultaneous anion/cation determinations.
The sequences for the processing of each sample are freely definable
within broad boundaries. The same is true for the start and final sequences that are executed once either before or at the end of a sample
series. With the help of the LEARN mode, which is provided for creating
process methods, methods can be created easily and stored as user
methods.
Preprogrammed standard methods for the most common modes of
operation allow to use the 766 IC Sample Processor directly, with only
little programming effort. The time frame can be given by the IC Sample
Processor; alternatively, the whole sequence can be managed by the
«IC Metrodata» remote control software via the «Queue» (sample table). The RS232 interface built in as standard allows remote control of
the IC Sample Processor from a PC.

1 Introduction
• 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 766 IC Sample Processor, 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.
1.5.2 General safety rules
• Install splash protection
To avoid any danger of injury by the needle, the splash protection
must always be installed when operating the 766 IC Sample Processor!
• Install plug cover
To prevent any contamination of the mains and remote connection by
spilled solvents or chemicals, the plug cover must always be installed
when operating the 766 IC Sample Processor !
• Do not use caps together with the PEEK tube
If you are using the 6.1835.000 PEEK needle, the sample tubes may
not be sealed with caps because they cannot be pierced by the PEEK
needle and the needle may be damaged thereby.
• Handling of solvents
Check the pump tubing and all input and output leads periodically for
possible leaks. Follow the relevant instructions regarding the handling
of flammable and/or toxic solvents and their disposal.
• Regular exchange of pump tubings
Pump tubings constitute consumable material and must be replaced
from time to time (see section 6.3.3). 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
(collection device for any liquid which may leak out).

2.3.8 Tubing connections 766 – 733
For transferring the sample from the 766 IC Sample Processor to the
injection valve of the 733 IC Separation Center the following tubing
connections must be made:
Pump tubings are consumable material with a lifetime which depends
on the contact pressure (see section 6.3.3). This is why the tubing
cartridges should be raised completely by loosening snap-action lever
1717 on the right-hand side if the pump is to remain switched off for a
considerable length of time (the set contact pressure remains unchanged).
The 6.1826.0X0 pump tubing is made of PVC and must not be used
for rinsing with solutions which contain acetone. In such cases, rinse
with different pump tubing or a different pump.
Install pump tubing
1
• Release tubing cartridge 1313 from holding clamp 1616 by
pressing down snap-action lever 1717 and remove from
mounting pin 1212 on the 766 IC Sample Processor (see Fig.
1).
• Press contact pressure lever 1515 on the tubing cartridge down
as far as it will go.
• Insert pump tubing 1010 in the tubing cartridge 1313 as shown in
Fig. 9. The black-black stopper 3636 must click into the corre-
sponding holder on the left-hand side of the tubing cartridge.
• Place the tubing cartridge 1313 on mounting pin 1212 and press
down on the right-hand side until snap-action lever 1717 clicks
into position on holding clamp 1616. Take care that no kinks are
formed in the pump tubing.

2.3.9 Tubing connections 766 – 754
If the 766 IC Sample Processor is used for an IC system with sample
dialysis (see section 2.4.6), the peristaltic pump at the 754 Dialysis Unit
is used for sample conveying instead of the pump at the 766 IC Sample
Processor. The tubing connections between the 754 Dialysis Unit 754
and the 733 IC Separation Center 733 have to be made as shown in
Fig. 8 of the 754 Instruction for Use. The only change concerns the inlet
of the sample, which is installed as follows:
Install a PEEK compression fitting 6.2744.010 on the inlet end of the
PTFE tubing 2626 (6.1803.030, see Fig. 8 of the 754 Instruction for Use)
