1.1 Instrument description
1 Introduction
1.1 Instrument description
The 812 Valve Unit is an instrument with one or two electrically driven
ein 6-port injector valves. Two different versions of the 812 Valve Unit
are available:
2.812.0010 Valve Unit with 1 valve
2.812.0020 Valve Unit with 2 valves
Valve parts in contact with the eluent are manufactured out of PEEK
material. The instrument is equipped with an external power supply so it
can be operated as a stand alone unit and is independent of other
Metrohm devices.
The 812 Valve Unit can be used for a variety of different applications:
• In combination with the 817 Bioscan or the 791 VA Detec-
tor, the 812 Valve Unit is used as the injector for the systems.
• With the 812 Valve Unit, a 761 Compact IC can be up-
graded to be a combined anion an cation system.
• In combination with the 816 Eluent Selector, the 2-port
version can be used for automatic column switching with
an intermediate rinsing step.
• The 812 Valve Unit can also be used in a large variety of
sample preparation techniques, like for cutting techniques, or switching between different sample streams.

1 Introduction
1.4 Safety notes
While electrical safety in the handling of the 812 Valve Unit is assured in
the context of the specifications IEC 61010-1 (protection class 1), the
following points should be noted:
• Mains connection
The mains connection must be effected in accordance with the
instructions in section 2.2.
• Opening the instrument
Inside the instrument there are no parts which must be set or adjusted
by the user.
If the 812 Valve Unit is connected to the power supply, the instrument
must not be opened nor must parts be removed from it. Hence,
before opening the instrument, always ensure that the power supply
unit is disconnected from connection 7!
• 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 812 Valve Unit, 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.
