3.7 Temperature control
The DS2500 Liquid Analyzer supports a temperature range between 25 °C
and 80 °C. The minimum temperature that can be set must be 10 °C
above the ambient temperature T
min
= T
ambient
+ 10 °C
To achieve a temperature of 25 °C, the ambient temperature must be
15 °C. As the ambient temperature in most laboratories is approx. 25 °C,
Metrohm recommends to set the temperature to a minimum of 35 °C.

3.8.1 Calibrating the instrument
The DS2500 Liquid Analyzer is calibrated with an external wavelength
standard
(see "Calibration with an external wavelength standard", page
13) and with an internal wavelength standard (see "Calibrating the
instrument with an internal wavelength standard", page 13) .
WARNING
Hot surface
Danger of burning due to hot components. The sample holder can be
heated to a maximum of 80 °C. After operation, the sample compart-
ment, the sample holder and the sample vessel are very hot.
￭
Wear protective gloves when handling sample holders and samples.
