1 Introduction
1.1 Instrument description
The 941 Eluent Production Module allows you to produce eluent for
your IC system from a concentrate and ultrapure water as needed and in a
software-controlled manner.
Thanks to the built-in Level Control, the instrument is capable of monitoring the liquid levels in up to four liquid containers, if they are equipped
with level sensors.
A level sensor for the eluent bottle is indispensable for the automated production of eluent and is contained in the scope of delivery of the 941 Eluent Production Module. However, we recommend using level sensors to
also monitor the bottle with the concentrate and the ultrapure water container. Additional level sensors are available as optional accessories in various versions.
1 Introduction
The 941 Eluent Production Module is operated with the MagIC Net software. If the 941 Eluent Production Module is connected to a 940 Professional IC Vario instrument, MagIC Net automatically detects the 941 Eluent Production Module and checks its functional capability. It controls and
monitors the entire IC system including all connected instruments; it evaluates the measured data and manages it in a database.
1.1.1 Intended use
The 941 Eluent Production Module is an instrument for the automated
production of eluent for ion chromatography systems. It can monitor the
levels of various liquid containers and, where necessary, perform appropriate actions controlled by the software.
The present instrument is suitable for processing chemicals. Usage of the
941 Eluent Production Module therefore requires the user to have basic
knowledge and experience in handling toxic and caustic substances.
Knowledge with respect to the application of the fire prevention measures
prescribed for laboratories is also mandatory.

940 Professional IC Vario. To accomplish this, the base tray of the ion
chromatograph has to be removed and installed again under the 941 Eluent Production Module (see Chapter 4.2.2.1, page 11).
As an alternative, the 941 Eluent Production Module can be set up
together with other instruments with the same footprint in a separate
stack next to the ion chromatograph. We recommend that a bottle holder
(6.2061.100) and a base tray (6.2061.110) be installed for each stack of
instruments.
4.2 Base tray and bottle holder
4.2.1 Basic information on base tray and bottle holder
The base tray (6.2061.110) and bottle holder (6.2061.100) protect IC
instruments from dust, dirt and leaking fluids. The supply bottles for eluent
and auxiliary solutions can be positioned neatly on the bottle holder.
In a complex IC system, several different instruments may be used, such as
an analyzer, an extension module and a detector. These instruments can
be set up in one or more stacks. We recommend that a base tray and bottle holder be mounted for each stack of IC instruments.

9 Warranty (guarantee)
Metrohm guarantees that the deliveries and services it provides are free of
defects in materials, design or manufacturing.
The general warranty period is 36 months (exclusions below) from the
date of delivery, or 18 months in the event of continuous operation. The
warranty remains valid on the condition that the servicing is provided by a
service organization authorized by Metrohm at defined intervals and with
a defined scope.
The warranty period for anion suppressors of the type "MSM" is 120
months from the date of delivery or 60 months in the case of continuous
operation.
The warranty period for IC separation columns is 90 days after start-up.
For third-party components that are recognizable as such, the manufacturer's warranty regulations apply.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
For instruments sold under the Metrohm NIRSystems brand, a full 16month warranty is applicable. In the event of continuous operation, the
warranty period is reduced by half.
Consumables and materials with limited storage life and glass breakage in
the case of electrodes or other glass parts are excluded from the warranty.
Warranty claims cannot be asserted if the ordering party has failed to
meet its payment obligations according to schedule.
During the warranty period, Metrohm undertakes either to replace free of
charge or to credit the purchaser for any modules or components that can
be shown to be faulty. Any transport or customs fees that may apply are
the responsibility of the ordering party.
The precondition for this is that the ordering party has to specify the article number, the article designation, an adequate error description, the
delivery date and (if applicable) the serial number or chip data in the Support Tracker. Metrohm then decides whether a replacement or a credit
note is to be issued or whether the faulty part has to be returned using
the Return Material Authorization (RMA). If a replacement or credit note is
issued, the ordering party undertakes to store the faulty part for at least
24 months in accordance with the current storage directives (in compliance with ESD guidelines) and to hold it in readiness for onsite inspection
or for return shipment to Metrohm. Metrohm reserves the right to invoice
the ordering party for these articles, including retroactively, in the event of
noncompliance with these preconditions.

9 Warranty (guarantee)
The same warranty periods that are specified for a corresponding new
part apply to parts that are replaced or repaired within the above-mentioned warranty periods. However, replacement or repair of a part does
not extend the warranty period of the entire system.
Deficiencies arising from circumstances that are not the responsibility of
Metrohm, such as improper storage or improper use, etc., are expressly
excluded from the warranty.
Metrohm also offers a 120-month spare parts availability guarantee and a
60-month PC software support warranty, calculated from the date on
which the product is withdrawn from the market. The content of this warranty is the ability of the customer to obtain functioning spare parts or
appropriate software support at market prices during the time of the warranty period. This does not apply for software products sold under the
Metrohm NIRSystems brand.
If Metrohm AG is unable to meet this obligation due to circumstances
beyond the control of Metrohm AG, then the ordering party shall be
offered alternative solutions at preferential conditions.
