Surface area and pore analyzer enables speed and precision
This company’s new Nova series (photo) for measuring surface area and pore characteristics has been designed to deliver speed and precision without tradeoffs. Consisting of four models, the Nova series delivers high analysis throughput 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 Brunauer-Emmett-Teller (BET) analyses of up to four samples can be performed in as little as 20 min. High throughput is combined with high precision and sensitivity. Exclusive features, like TruZone active coolant-level control, enhance 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 even with an absolute surface area as low as 2 m2 in the sample cell. Stand 2830 — Anton Paar USA Inc., Ashland, Va.
