The Anton Paar CHC plus+ chamber is designed for in situ powder X-ray diffraction measurements in reflection geometry and allows performing both high- and low-temperature experiments and experiments with controlled temperature and humidity conditions. The entire temperature range accessible with this chamber is from – 180 ºC to 400 ºC. If cooling below -10 ºC is not required, compressed air cooling can be used instead of liquid nitrogen cooling. The relative humidity can be changed from 5 to 95 %rH at temperatures from 10 to 80 ºC. Optionally a beam knife can be placed above the sample for improved low-angle background.
The most versatile humidity chamber
The CHC plus+ is a unique chamber for in situ X-ray diffraction on powder samples not only at low to medium- high temperatures in dry atmosphere, but also for experiments with controlled temperature and humidity conditions. It is ideal for the in situ study of dynamic crystal structure changes, phase transformation, chemical reactions, etc. in both organic and inorganic powders. Furthermore basic thin film analysis (phase composition, basic reflectivity) and residual stress measurements on relatively thin samples can also be done with this chamber.
