1.1 Instrument description
1 Introduction
The NIRS DS2500 Analyzer is a compact measuring instrument for reflection measurement in the near-infrared wavelength range. The polychromatic light is dispersed by the monochromator built into the NIRS DS2500
Analyzer into monochromatic wavelengths before striking the sample. This
reduces sample heating. The instrument operates in the range from 400
to 2,500 nm.
The NIRS DS2500 Analyzer is designed for quality monitoring in production processes and can be applied for the following purposes:
￭ Quick and non-destructive incoming goods inspection of raw materials
￭ Production process monitoring
￭ Final inspection of finished products
The NIRS DS2500 Analyzer can be used to measure the following sample
types:
￭ Solid samples: powders or granulated substances
￭ Liquid samples: liquids or suspensions
The NIRS DS2500 Analyzer is a robust instrument that is resistant to moisture, dust, vibrations and temperature fluctuations. As a result, it can be
operated in a variety of production facilities.
The NIRS DS2500 Analyzer is operated with the Vision software via an
external computer.

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.
