The DAC can be heated externally (with respect to the sample chamber between the anvils' culets) when the entire DAC is placed in an oven or in a hot stream of air from an electrical heater (Fourme, 1968 ; Allan & Clark, 1999 ; Podsiadło &

For example, in situ crystallization of halogen derivatives of acetic acid could only be performed in a DAC chamber with tungsten gaskets (Gajda &
Katrusiak, 2009). In these experiments, the gasket was gradually eroded by the acid, but after its ...
