1 Introduction
This manual gives you a comprehensive overview of the installation and
maintenance of the DS2500 Solid Analyzer. The DS2500 Solid Analyzer is
operated with the control software. You can find information on operat-
ing the instrument in the tutorial and in the manual for the control soft-
ware.
NOTICE
You can request application descriptions in the form of
Application Notes and Application Bulletins from your
Metrohm representative or download them from
http://www.metrohm.com.
1.1 Instrument description
The DS2500 Solid Analyzer is a compact measuring instrument for reflec-
tion measurement in the near-infrared wavelength range. The polychro-
matic light is dispersed by the monochromator built into the DS2500 Solid
Analyzer into monochromatic wavelengths before striking the sample. This
reduces sample heating. The instrument operates in the range from 400
to 2500 nm.
The DS2500 Solid Analyzer is designed for quality monitoring in produc-
tion 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 DS2500 Solid Analyzer can be used to measure the following sample
types:
￭Solid samples: powders or granulated substances
￭Liquid samples: liquids or suspensions
The DS2500 Solid Analyzer is a durable 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 DS2500 Solid Analyzer is designed for offline operation in the labora-
tory or atline operation in the production process.
The DS2500 Solid Analyzer is operated with the control software via an
external computer.

1.2 Intended use
The DS2500 Solid Analyzer is designed for use in production facilities. The
DS2500 Solid Analyzer can be used for incoming goods inspection or
atline or offline for production process monitoring.
Usage requires the user to have basic knowledge and experience in han-
dling chemicals. Knowledge with respect to the application of the fire pre-
vention measures prescribed for laboratories is also required.
Adherence to this technical documentation and compliance with the
maintenance specifications make up an important part of intended use.
Any utilization in excess of or deviating from the intended use is regarded
as misuse.
Specifications regarding the operating values and limit values of individual
products are covered in the "Technical specifications" section (see chapter
6, page 36).
