5 Operation and maintenance
5.1 General notes
5.1.1 Care
The 772 Pump Unit requires appropriate care. Excess contamination of the
instrument may result in functional disruptions and a reduction in the lifetime of the sturdy mechanics and electronics.
Spilled chemicals and solvents should be removed immediately. Above all,
the plug connections on the rear of the instrument (in particular the mains
connection socket) should be protected from contamination.
Caution
Although this is extensively prevented by design measures, the mains
plug should be unplugged immediately if aggressive media have penetrated the inside of the instrument, so as to avoid serious damage to
the instrument electronics. In such cases, Metrohm Service must be
informed.
5 Operation and maintenance
5.1.2 Maintenance by Metrohm Service
Maintenance of the 772 Pump Unit is best carried out as part of an annual
service, which is performed by specialist personnel of the Metrohm company. If working frequently with caustic and corrosive chemicals, a shorter

Aggressive liquids
Leaking liquids can pose a risk of injury and damage instruments.
￭ Use suitable tubing only.
￭ Regularly check tubing for proper fastening and for damage and
wear.
In every case, the user has sole responsibility with regard to suitability
and safety of pump tubing. Therefore, it is extremely important that
before each use, the safety and effectiveness of tubing is tested based
on application-specific laboratory, field or clinical tests.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Warning
Note
5.2.1 Selecting the pump tubing
The most important decision when using peristaltic pumps is the selection
of suitable tubing material. Always use tubings particularly intended for
peristaltic pumps.
The 772 Pump Unit is shipped with PharMed® pump tubing (6.1826.100,
ø 6.4/9.6 mm, see Chapter 5.2.5) made of thermoplastic polypropylene,
which is highly suitable for aqueous media.
If you need other tubings for your application, take care to ensure the following points when evaluating the pump tubings:
￭ Chemical resistance
￭ Pressure build-up in the pump tubing
￭ Sterilizability
￭ Temperature of the pump medium and the environment
￭ Viscosity of the liquid
￭ Permeability of the pump tubing
￭ Demanded flow rate
￭ Tubing dimensions
We recommend using PVC, silicone, Viton® and PharMed® as the tubing
materials. Contact your laboratory dealer for information on suitable products and their data sheets.
￭￭￭￭￭￭￭￭
16
772 Pump Unit
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
5.2.2 Suitability test for tubing materials
Place a piece of the tubing in question for 48 hours in a closed container
filled with the liquid in question. Then examine the piece of tubing for
signs of swelling, embrittlement or other damage.
5.2.3 Tubing dimensions
Note
Use tubing with a wall thickness of 1.6 mm only.
The largest usable inner diameter is 6.4 mm.
5.2.4 Tubing lifetime
The pump tubing has a limited lifetime and therefore has to be replaced
regularly. The following are examples of factors that can influence the lifetime of tubing in peristaltic pumps:
5 Operation and maintenance
￭ Chemical resistance of the pump tubing
￭ Pump rate (rotational speed)
￭ Properties of the pumped liquid
￭ Outlet pressure
￭ Ambient temperature
￭ Shearing force of the rollers
￭ Twisted or kinked tubing
￭ Tubing too long
￭ Wall thickness of 1.6 mm not complied with
772 Pump Unit
￭￭￭￭￭￭￭￭
17
5.2 Pump tubings
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Note
￭ If the tubing is not tightened sufficiently around the rotor, this has a
negative impact on the lifetime of the tubing, as in this case the tubing tends to fold up. If the tubing is tightened too much, the flow is
restricted.
￭ The tubing will last longer if the pressure clamp is detached when
the pump is not in use.
￭ In order to achieve good repeatability of flow rate following a
change in tubing, it is imperative that you always select the same
tubing length.
Before changing tubing:
￭ Pump all of the liquid out of the tubing so that none remains.
￭ Pull out the connection cable of the peristaltic pump to prevent acci-
dental starting of the pump.
￭ Detach the pressure clamp, open the tubing clamps and remove the
tubing.

8 Conformity and warranty
8.1 Quality Management Principles
Metrohm Ltd. holds the ISO 9001:2000 Certificate, registration number
10872-02, issued by SQS (Swiss Association for Quality and Management
Systems). Internal and external audits are carried out periodically to assure
that the standards defined by Metrohm’s QM Manual are maintained.
The steps involved in the design, manufacture and servicing of instruments
are fully documented and the resulting reports are archived for ten years.
The development of software for PCs and instruments is also duly documented and the documents and source codes are archived. Both remain
the possession of Metrohm. A non-disclosure agreement may be asked to
be provided by those requiring access to them.
The implementation of the ISO 9001:2000 quality management system is
described in Metrohm’s QM Manual, which comprises detailed instructions on the following fields of activity:
8 Conformity and warranty
Instrument development
The organization of the instrument design, its planning and the intermediate controls are fully documented and traceable. Laboratory testing
accompanies all phases of instrument development.
Software development
Software development occurs in terms of the software life cycle. Tests are
performed to detect programming errors and to assess the program’s
functionality in a laboratory environment.
Components
All components used in the Metrohm instruments have to satisfy the quality standards that are defined and implemented for our products. Suppliers of components are audited by Metrohm as the need arises.
Manufacture
The measures put into practice in the production of our instruments guarantee a constant quality standard. Production planning and manufacturing
procedures, maintenance of production means and testing of components, intermediate and finished products are prescribed.
Customer support and service
Customer support involves all phases of instrument acquisition and use by
the customer, i.e. consulting to define the adequate equipment for the
analytical problem at hand, delivery of the equipment, user manuals, train-

8.2 Warranty (Guarantee)
ing, after-sales service and processing of customer complaints. The
Metrohm service organization is equipped to support customers in implementing standards such as GLP, GMP, ISO 900X, in performing Operational Qualification and Performance Verification of the system components or in carrying out the System Validation for the quantitative determination of a substance in a given matrix.
8.2 Warranty (Guarantee)
Metrohm guarantees that the deliveries and services it provides are free of
errors 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 is 120 months from the date of
delivery or 60 months in the event 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.
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 customer has failed to meet his
payment obligations according to schedule.
During the warranty period, Metrohm undertakes either to replace free of
charge or to credit the purchaser for any assemblies or components that
can be shown to be faulty. Any transport or customs fees that may apply
are the ordering party’s responsibility.
The precondition for this is that the ordering party must use the Return
Material Authorization (RMA) to report the faulty part, along with specification of the article number, the article designation, an adequate error
description, the delivery date and (if applicable) the serial number or the
chip data, respectively. In addition, the ordering party undertakes to store
the faulty part for at least 24 months in accordance with 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 pre-conditions.
￭￭￭￭￭￭￭￭
26
The original warranty periods for the original part apply to parts that are
replaced or repaired under the above-referenced warranties (no extension
of the warranty period).

8 Conformity and warranty
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.
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.
