1.1 Instrument description
1 Introduction
1.1 Instrument description
The 818 IC Pump is a serial dual piston pump especially developed for
ion chromatography and optimized for use with Metrohm ion
chromatographic instruments (e.g. 819 IC Detector and 820 IC
Separation Center). The 818 IC Pump operates with minimal residual
pulsation and has an excellent flow constancy. All wet parts of the
pump are metal free.
The 818 IC Pump is completely remote controlled by the Metohm
software «IC Net» (version 2.3 or higher). All functions are fast and
easily accessible via software and can be clearly arranged at the
monitor. To assure optimum operational reliability, both lower and
upper pressure limit values can be set. If such a limit is reached, the
pump switches itself off automatically. An additional purge valve allows
rapid removal of air from the pump system.

1 Introduction
1.4 Safety notes
1.4.1 Electrical safety
While electrical safety in the handling of the 818 IC Pump is assured in
the context of the specifications IEC 1010-1 (protection class 1, degree
of protection IP40), the following points should be noted:
• Mains connection
Set the mains voltage and check the mains fuse and mains
connection in accordance with the instructions in section 2.6.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
If the 818 IC Pump is connected to the power supply, the instrument
must not be opened nor must parts be removed from it, otherwise
there is a danger of coming into contact with components which are
live. Hence, always disconnect the instrument from all voltage sources
before you open it and ensure that the mains cable is
disconnected from mains connection 10 !
• 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 818 IC Pump, 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 safety rules
• 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.

2.1 Setting up the instrument
2 Installation
2.1 Setting up the instrument
2.1.1 Packaging
The 818 IC Pump is supplied together with the separately packed
accessories in special packagings containing shock-absorbing 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 assure
transport of the instruments free from damage.
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 6.2). In the case of transport damage, see
instructions in section 6.5.1 "Warranty".
2.1.3 Location
Position the 818 IC Pump in the laboratory at a location convenient for
operation, free from vibrations and protected against a corrosive
atmosphere and contamination by chemicals.
To avoid disturbing temperature influences on the insulated column
compartment, the pump and eluent reservoir must be protected
against direct sunlight.
2.1.4 Arrangement of the instruments
The 818 IC Pump should always be at the very bottom of a IC system.
The 818 IC Pump 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 liquids.

2 Installation
2.2 Mounting the pump head
1 Remove the transportation lock
To ensure that the pump drive is not damaged during transport
a black plastic block is mounted in place of the pump head on
the right side of the 818 IC Pump front panel. This transport
safeguard block has to be removed after undoing the four
screws 9.
To avoid any damage to the pump head, the protective block must be
remounted if the pump has to be moved any great distance.
2 Mounting the pump head
The Pump Head 8 (6.2824.100) with integrated piston units is
unpacked and fixed in place of the transport safeguard block
with the four hexagon screws 9as shown in Fig. 2 .
To ensure that the pump head is not positioned wrongly, the holes at
the rear for the clamping bolts have different depths, i.e. 1 clamping
bolt is longer than the rest. The deepest hole must naturally
accommodate the longest bolt. If this is not the case, the pump will
not function properly.
3 Connecting capillary to pump head
The connection capillary 6 fastened to purge valve 2 is
screwed onto the pump head 8 as shown in Fig. 2.

2.3 Attaching the accessories
2.3 Attaching the accessories
2.3.1 Capillaries
Some of the connections under high pressure between the 818 IC
Pump and the IC system must be set up by the user, see section 2.4.
For that the 6.1831.010 PEEK capillary (i.d. = 0.25 mm, o.d. =
length = 3 m) supplied in the accessories of the 818 IC Pump can be
used.
Capillaries fitted with new connectors must have a perfectly flat cut
surface. For PEEK capillaries it is best to use the 6.2621.080
Capillary tubing cutter

For the connection of 6.1831.010 PEEK capillaries or of the 6.1834.000
PTFE aspirating tubing, the supplied 6.2744.010 PEEK Compression
fittings are used. It is best to proceed as follows:
1 Mount compression fitting
Slide a compression fitting 20 (6.2744.010) over the end of the
capillary 19 to be fastened as shown in Fig. 3.
2 Insert capillary in connection
Push capillary end in the corresponding connection as far as it
will go (to avoid dead volume).
3 Tighten compression fitting
Tighten compression fitting 20 by hand (never use tools).
2.3.2 Pulsation dampener
To protect the column material against pressure drops caused by the
injector, the use of a pulsation dampener connected between the pump
and the injection valve of the 820 IC Separation Center is
recommended. The optional 6.2620.150 Pulsation dampener MF is
very well suited to this purpose (see section 6.3).
The metal-free 6.2620.150 Pulsation dampener is supplied fully
assembled and has two connections for capillaries, for which two
818 IC Pump / 8.818.1023 Instructions for Use

2 Installation
6.2744.010 PEEK compression fittings can be used. The flow direction
is arbitrary. The pulsation dampener is positioned in the interior of the
820 IC Separation Center on the base below the injection valve (see
819/820 Instructions for Use).
The pulsation dampener is filled with isopropanol when new. Rinse
your IC system carefully after the first installation of a new pulsation
dampener.
2.3.3 Filter unit PEEK
The 6.2821.120 Filter unit PEEK 24 supplied (see Fig. 4) serves to
avoid contamination of the piston seals by abrasive particles and can
be used in the pressure range 0…30 MPa (0…300 bar). The filter unit
consists of the housing 21, the filter 22 and the connector 23 to be
screwed into the housing 21. For the connection of capillaries 19, PEEK
compression fittings 20 (6.2744.010) must be used.
New filter 22 are available as an option with the ordering number
6.2821.110 (10 pieces).
For the connection of the filter unit, please note the flow direction
arrow printed on the housing.
The filter unit is filled with isopropanol when new. Rinse your IC system
carefully after the first installation of a new filter unit.
