Anton Paar’s Nova series of surface area and pore analysers has been designed from the ground up to deliver velocity. Consisting of four models, it heralds a new era in surface area and pore characterisation in which speed and precision will no longer be an either-or choice.
High analysis throughput is achieved by combining four sample preparation stations with up to four analysis stations in a single compact footprint. Patented features like NOVA analysis mode combined with a suite of intelligent dosing algorithms significantly reduce measurement times. Five-point BET analyses of up to four samples can be performed in as little as 20 minutes.
These features are combined with high levels of precision and sensitivity. The devices’ TruZone active coolant level control enhances analysis sensitivity by actively maintaining the cryogen level to ensure a small cold zone around the sample cell. A dedicated P0 cell and transducer constantly monitor the saturation pressure over the course of a measurement to provide highly accurate relative pressure readings, yielding precise and reproducible isotherms. Reproducibility above 2% can now be obtained with an absolute surface area as low as 2 sqm in the sample cell.
