Quantachrome has launched a temperature controlling device for thermostatting gas sorption experiments.
The Cryocooler accessory has been specially designed sample holders for its manometric sorption analysers the Autosorb-iQ, the iSorb-HP and the older Autosorb-1.
According to the company, it will ensure the necessary temperature control for demanding and cutting-edge applications such as those intended to benefit the environment.
Quantachrome’s Cryocooler does not use liquefied gases, which have continuous evaporation from their holding dewar thus limiting analysis times.
Instead, it uses compressed helium gas as a refrigerant to achieve and control temperatures as low as 20kelvin for low pressure sorption measurements and as low as 75K for high pressure measurements.
Extending analysis time almost indefinitely, the Cryocooler actively controls the sample temperature at any value between the low limits above and its maximum of 320K (47 deg°C).
