The Flex family of high-performance adsorption analyzers for measuring surface area, pore size, and pore volume of powders and particulate materials. Standard methods or user customized protocols can be used to characterize adsorbents, catalysts, zeolites, MOFs, APIs, excipients, and a wide variety of porous and non-porous materials. The 3Flex is ideally suited for gas or vapor adsorption analysis of microporous (< 2nm) and mesoporous (2 to 50nm) materials and delivers superior accuracy, resolution and data reduction.
A chemisorption option extends the application range of Flex to both physical and chemical adsorption for characterizing the texture and active surface of catalysts, catalyst supports, sensors and a variety of other materials.
The TCD option adds dynamic chemisorption and temperature programmed methods, and further increases the analytical methods available in a single adsorption analyzer. The TCD option adds temperature programmed reduction (TPR), oxidation (TPO), desorption (TPD), and surface reactions (TPSR) for measuring textural properties and chemisorption. The TCD analysis range can be extended with an option for pulse chemisorption with the addition of an automated injection loop. The TCD also includes a pulse chemisorption TCD.
