6 Operation

Measurements with the DHS 1100 are performed in 
the same way as when using the standard sample 
stage for the diffractometer.

6.1 Preparing the Instrument

Before starting to work with the DHS 1100 make 
sure that the following safety requirements are ful-
filled:

In the temperature range between room tempera-
ture and 200 °C it is possible to work without the 
cooling gas and without the dome. At temperatures 
above 200 °C the dome has to be mounted and the 
air cooling must be on to guarantee sufficient heat 
removal from the dome and the housing of the 
DHS 1100.

For operation with a PEEK dome at elevated tem-
peratures a modification of the cooling system with 
a cooling nozzle for DHS 1100 is necessary.

For information about the temperatures of the 
dome, the housing and the goniometer after opera-
tion at 1100 °C for 1 hour, refer to 

Appendix A:

6.2 Mounting the Sample

6.2.1 Flat Samples

The DHS 1100 heating attachment is preferably 
used for flat and/or flake-shaped samples with a 
maximum diameter of 25 mm and a maximum thick-
ness of 2 mm. The recommended sample diameter 
is 15



20 mm and the recommended sample thick-

ness is 



1 mm. This ensures good clamping of the 

sample to the heating plate and maximum tempera-
ture homogeneity across the sample.

The sample is fixed on the sample plate with 
springs. The springs are supplied in the accessory 
box and can be easily exchanged by pulling them 
out of the small bore holes. Depending on the sam-
ple size, use either the large or the small springs for 
fixation.

CAUTION

Radiation

The DHS 1100 represents an open system and 
therefore is only allowed to be operated on goni-
ometers equipped with a radiation enclosure

CAUTION

Hot surface

During operation and even after turning off the 
heating, the sample stage and the dome can be 
hot. Make sure that all parts of the DHS 1100 are 
below 50°C before touching the instrument.

WARNING

Make sure that no inflammable material is lying 
below or near the DHS 1100 during operation.

CAUTION

Never touch the dome during operation espe-
cially when it is evacuated or at elevated tem-
peratures, because this may easily damage the 
dome.

CAUTION

• Make sure that the sample components do 

not react with the sample stage at elevated 
temperatures.

• Check the melting point of the sample 

before

the experiment and choose the temperature 
of the investigation correspondingly.
