Variable temperature (heated) Sample Holder
The Variable Temperature Cell is suitable for transmission measurements on liquid or solid samples. Temperatures can be set between ambient and 250 0C. The accessory comprises of an electrically heated cell jacket, electronic controller, THz transparent cell inserts and a modified sample compartment cover for the TPS spectra 3000 to maintain sample compartment purge.
Variable Temperature (cooled) Sample Holder
The cell consists of a vacuum jacket with a refrigerant dewar/cell holder assembly and Z-cut quartz windows. Sample cells are inserted into the heating block part of the dewar/cell holder and the whole system is operated within a vacuum environment maintained by the outer jacket. Using a combination of refrigerant and cell block heaters any temperature from -1900 C to 2500 Ccan be achieved. Typically liquid nitrogen is used as the coolant
