Precise measurements of surface area and porosity can be made with the Belsorp-Mini II gas and vapour adsorption analyser from BEL, which is now available in the UK from Merrow Scientific.
This instrument is used for the characterisation of porous or finely divided materials such as powders, pigments, catalysts, activated carbons and zeolites.
Pore sizes from 0.35 to 200nm in diameter can be measured, while very low specific surface areas down to 0.01m2/g can be measured with high accuracy and without the use of krypton gas.
The automated volumetric sorption analyser is equipped with five accurate pressure sensors, and up to three independent samples can be measured simultaneously.
This enables quicker results for quality control purposes, but provides the high resolution needed to meet most research requirements.
The Belsorp-Mini II's powerful software enables parameters to be set by novices and experts alike.
It also includes a one-click system check function that shows instrument status and diagnostics.
The instrument's Advanced Free Space Measurement (AFSM) feature increases accuracy and repeatability by compensating for dead volume in the sample tube.
It is suitable for applications in sectors such as chemical and petrochemical engineering, pharmaceuticals, paints and pigments, coatings, ceramics, building materials, food and textiles.
The Belsorp-Mini II is a smaller, lower priced version of the Belsorp-Max, also available from Merrow Scientific.
