Analysis of porous materials by gas adsorption: Nova Series
The NOVA Series instruments are the preferred choice of hundreds of laboratories worldwide. These fast, vacuum-volumetric gas sorption instruments provide research and quality control laboratories with the capacity they need to accurately determine specific surface areas and pore size distributions, at an affordable price. Combining two or four analysis stations with four sample preparation stations in one instrument reduces space requirements and maximizes performance. The integrated touchscreen makes operation even more intuitive and convenient.
Easy determination of specific surface areas and pore size distributions - the NOVA
The Nova series has been designed to make the entire analysis process simple and fast without sacrificing precision. The instrument has 4 degassing stations and up to 4 analysis stations and provides four 5-point BETs in 20 minutes with a reproducibility of 2%. Follow the analysis workflow on the tabs and you will learn which advantages Nova offers you and which features Nova is setting new standards in the characterization of surfaces and pores.
All devices in the NOVA series work independently and, in addition to the classic helium method for determining the free gas volume, also have the patented, time-saving helium-free NOVA method. The saturation vapor pressure can be determined continuously using a dedicated P0 pressure sensor, which increases the measurement accuracy and measurement speed. A level sensor (CLS) enables a constant, small cold zone in the measuring cell and thus high sensitivity of the pressure sensors over the entire measuring period (max. approx. 40 h). Three integrated gas connections allow great flexibility when choosing the adsorbent. With the ability to measure CO2 isotherms at 273 K, devices from the NOVA series can be used to determine the specific surface area and pore size distribution of microporous carbon.
The integrated touchscreen enables convenient work in stand-alone mode. Measurement and sample preparation programs can be called up directly from the touchscreen and up to four BET and pore analyzes can be started, while up to four samples are degassed in parallel and technically separately. Optionally, a computer can be connected to control the device directly with the software Kaomi for NOVA.
