2 TTK 600 - An Overview
The TTK 600 Low-Temperature Chamber is an attachment for 2-circle X-ray diffractometers with vertical
goniometer to cool and heat samples for in-situ X-ray diffraction.

Intended Use of the Instrument
The TTK 600 Low-Temperature Chamber has been
designed for use on powder X-ray diffractometers
with a vertical goniometer. The sample chamber is
mounted on the goniometer instead of the standard
(ambient) sample holder in order to heat or cool the
sample to a defined temperature while scanning the
sample with X-rays.
Different types of sample holders are available that
allow to perform X-ray scans either in reflection ge-
ometry, transmission geometry using capillaries or
transmission geometry for foils, pastes and also
powders. Two cooling options are available for the
instrument. With the liquid nitrogen cooling equip-
ment, the temperature range is -190 °C to 600 °C.
With the compressed-air cooling equipment the
temperature range is -20 °C to 600 °C. The sample
can be cooled/heated in vacuum or various gas at-
mospheres.
The sample temperature is controlled by a control
unit (CCU 100). This control unit is installed in spe-
cial compartments in the diffractometer or in an ex-
ternal rack beside the diffractometer.
TTK 600 should be used for powder samples (all
three types of sample holders) or foils and pastes
(transmission sample holder). The following sample
materials must not be investigated with TTK 600:
• radioactive samples
• samples that are self-igniting in air or when
exposed to humid gas.
If TTK 600 is operated under dynamic gas condi-
tions, gas flows through the chamber and sample
material can be released to the environment. This
must be taken into account when measuring sam-
ples that present a health hazard.

CAUTION
Risk of injury
Observe that in case of an unlikely malfunction
the highest possible temperature in the instru-
ment can be up to 900 °C. Do not use samples
that are self-igniting or form poisonous gases at
that temperature.
