The TTK 600 Low-Temperature Chamber is a non-ambient attachment for powder X-ray diffraction studies from -190°C to 600°C. Different sample holders allow investigating samples in reflection and transmission geometry. Samples can be measured in vacuum, air or inert gases. An antechamber option allows safe transfer of air-sensitive samples into the TTK 600.The TTK 600 fits to all common powder diffractometers and is the instrument of choice for X-ray structure analysis of various sample types at low and medium temperatures.
