The temperature is kept constant by means of a temperature sensor and a temperature
controller.

Temperature information is stored together with the spectra if the temperature has been
controlled by the OPUS software. Measurements during temperature ramps are only
possible with the OPUS measurement function Protein Dynamics (optional software
package OPUS/PRO) or the temperature control software LinkSys by Linkam.
5.3.2.3 Safety notes
The utilizable temperature range of the stage is minus 196°C to plus 600°C. So depend-
ing on the set temperature, the stage and the sample can become very hot or cold dur-
ing the operation.
➣ Attention: Depending on the property of the sample, it can dramatically change its
physical appearance (e.g. melt) or even ignite. For this reason, determine in
advance how the sample in question will behave at the intended temperature.
5.3.3 Heatable sample holder
5.3.3.1 General information
The heatable sample holder can be used in conjunction with both the manually-operated
and the motorized microscope stage. (See fig. 5.4a.) Note: Note: In case of the motor-
ized microscope stage, the heatable sample holder fits in the cut-out of the microscope
stage.
For measurements with the heatable sample stage, Bruker recommends using only the
15x objective.
The sample is placed in the round opening of the sample holder. This opening has a
diameter of 13 mm which is the standard pellet size. Smaller samples can be fixed on or
sandwiched between two IR-transparent pellets. The pellet material (e.g. KBr or NaCl)
should have a low refraction index in order to reduce reflection losses and minimize
focus shifts as far as possible. To ensure a good contact between sample and pellet use
the supplied tightening ring to compress the sample sandwiched between two pellets. In
doing so, the sample thickness and the occurrence of possible interferences are
reduced.

CAUTION
Risk of burn injuries or frostbites caused by touching the heating /
freezing stage
➣ Do not touch the hot or cold stage.
➣ Wait until the stage and the sample have cooled down or warmed up sufficiently
before touching the stage and removing the sample.
